UVA, UVB, and UVC – What Do They Do, and Where Can You Find Them?
Most people have heard of UVA and UVB, but what about UVC - or the difference between UVA1 and UVA2? Let's start with the shortest wavelengths. UVC (100–280 nm) is naturally present in sunlight, but it is almost completely absorbed by the Earth's ozone layer, so it doesn't normally reach the Earth's surface. UVC radiation is highly effective at killing bacteria, viruses, and other microorganisms, which is why it is widely used in germicidal lamps.
You may wonder why these lamps appear to emit visible light if UVC itself is invisible. The blue or purple glow doesn't come from the UVC radiation itself - it comes from materials inside the lamp that emit visible light. This glow simply indicates that the lamp is operating. Despite the visible light, you should never remain in a room while an unshielded UVC lamp is on, as direct exposure to UVC radiation can damage your skin and eyes. This technology is commonly used in laboratories, hospitals, and other environments where disinfection is essential.
Next is UVB (280–315 nm). A simple way to remember its effects is that the "B" stands for "Burn." UVB is primarily responsible for sunburn because it affects the epidermis, the outermost layer of the skin. However, UVB also plays an important role in the production of vitamin D, which is essential for maintaining healthy bones and supporting a properly functioning immune system. A vitamin D deficiency can contribute to conditions such as osteoporosis.
Finally, there's UVA (315–400 nm). The "A" stands for "Aging" because UVA is the primary cause of premature skin aging. Unlike UVB, UVA penetrates much deeper into the skin, reaching both the epidermis and the dermis. Another important difference is that UVA can pass through glass, meaning you can still be exposed to it indoors or while driving.
Both UVA and UVB can damage skin cells. Prolonged exposure increases the risk of skin cancer, accelerates premature skin aging, and contributes to oxidative stress. That's why wearing sunscreen every day—even when you're indoors near windows or driving—is an important part of protecting your skin.
Should You Wear Sunscreen at Home?
We already know that UVA rays can penetrate glass, but does that mean you should wear sunscreen indoors? The answer is yes - especially if you spend a lot of time near windows. If you work by a window or sit in direct sunlight for extended periods, applying sunscreen in the morning is a good idea. You can also reduce UV exposure by installing UV-protective window film or simply keeping your blinds or curtains closed during the sunniest hours of the day.
Ultimately, the decision is up to you and your daily routine. Personally, I keep my blinds closed throughout the morning because my windows face east. By the afternoon, the direct sunlight has mostly disappeared. Since I apply sunscreen every morning and reapply it throughout the day, I already have protection in place by the time the afternoon sun reaches my windows.
What's the Difference Between Mineral and Chemical Sunscreens?
There are two main ways to classify sunscreens: mineral (inorganic) and chemical (organic).
Mineral sunscreens use inorganic UV filters—most commonly zinc oxide and titanium dioxide. These ingredients provide broad-spectrum protection, especially when used together. One drawback is that they can leave a white cast, particularly on deeper skin tones, although many modern formulations have significantly reduced this effect.
Chemical sunscreens use organic, carbon-based UV filters. These filters are typically lightweight, spread easily across the skin, and generally don't leave a white cast. Modern formulations often combine multiple UV filters to provide broad-spectrum protection while maintaining an elegant, comfortable finish.
Neither type is inherently better than the other. The best sunscreen is the one you'll apply generously, reapply as needed, and wear consistently every day. For some people - especially those with post-inflammatory hyperpigmentation (PIH) or melasma - tinted mineral sunscreens containing iron oxides may provide additional protection against visible light, which can contribute to hyperpigmentation. In these cases, a tinted sunscreen with iron oxides may offer an extra layer of protection beyond UV radiation alone.
Sunscreen Reapplication
Most sunscreen brands recommend reapplying sunscreen every two to three hours. The reason is simple: throughout the day, sunscreen gradually wears off. We sweat, touch our faces, wear clothing that rubs against our skin, and wipe our skin with towels or tissues. All of these everyday activities can remove part of the protective layer, reducing its effectiveness. It's also important to remember that everyone responds differently to UV exposure. One person's skin may start to burn after just five minutes in the sun without protection, while someone else may be able to stay outside much longer before experiencing the same effect. Factors such as skin tone, UV index, time of day, altitude, and individual sensitivity all influence how quickly UV damage can occur.
As a general rule, reapplying sunscreen every two hours - or every two to three hours, depending on your level of sun exposure - helps maintain consistent protection throughout the day. If you're swimming, sweating heavily, or drying your skin with a towel, you should reapply even sooner, following the instructions on your sunscreen's label.
Japanese vs. Korean Sunscreens: Which Is Better?
I believe both Japan and Korea produce excellent sunscreens, but neither country gets every formula right. There are outstanding products from both, as well as some I wouldn't personally recommend. Skincare is highly individual, and a sunscreen that works perfectly for one person may not suit someone else.
One difference I've noticed is that many Japanese sunscreens contain a higher amount of alcohol. That's not necessarily a bad thing - alcohol can help create lightweight, fast-drying formulas with elegant finishes. However, these sunscreens often feel drier on the skin than many Korean alternatives, which may not be ideal for people with dry or sensitive skin.
Japanese brands are also known for their innovations. For example, Athlizm IR introduced impressive technology designed to maintain sunscreen performance under harsh conditions. While the concept sounded excellent on paper, the formula simply didn't work well for my skin.
Korean sunscreens, on the other hand, often place a stronger emphasis on the skincare experience. In addition to providing UV protection, many formulas include moisturizing, soothing, or barrier-supporting ingredients, making sunscreen feel like an extension of a daily skincare routine rather than just a protective product.
Ultimately, neither Japanese nor Korean sunscreens are inherently better. The best choice depends on your skin type, preferences, and the finish you're looking for. If you prefer lightweight, water-resistant formulas, you may enjoy Japanese sunscreens. If you're looking for a more hydrating, skincare-focused formula, Korean sunscreens may be a better fit.
Meet The Brand: Anessa
Anessa is a Japanese sunscreen brand established in 1992. It belongs to Shiseido Corporation and has become one of the most recognized suncare brands in Asia. Although Anessa has more than 30 years of experience developing sunscreen formulas, the brand also benefits from Shiseido’s more than 100 years of research into ultraviolet protection. Shiseido launched its first UV-protective product, Uviolin, in 1923.
Anessa is particularly known for combining high UV protection with innovative sunscreen technologies. Its formulas have featured technologies such as Aqua Booster, which helps strengthen and even out the UV-protective film when exposed to sweat and water, and Auto Booster, which can respond to moisture in the air. The newer Perfect UV Skincare Milk also introduced Auto Repair Technology, designed to help automatically repair gaps and uneven areas in the sunscreen film caused by facial movements such as talking, smiling, and blinking.
Anessa Perfect UV Sunscreen Skincare Milk - Product Claims
Anessa Perfect UV Sunscreen Skincare Milk is a sunscreen designed to withstand water, heat, and humidity. It provides the highest level of UV protection under the Japanese rating system, with SPF 50+ and PA++++. Around 50% of the formula is dedicated to skincare ingredients, including Super Hyaluronic Acid and Green Tea Extract. The sunscreen is water-resistant for up to 80 minutes and features Shiseido’s Auto Booster Technology.
Anessa Perfect UV Sunscreen Skincare Milk - Packaging
Although I bought the smaller 20 ml version of the Anessa Perfect UV Sunscreen Skincare Milk, which was released for the Korean market, it came in paper packaging. I was surprised by this because Nivea and Biore sunscreens, for example, often come in a combination of paper and plastic packaging.
The bottle of Anessa Perfect UV Sunscreen Skincare Milk has a cult-favorite design: a gold bottle with blue accents. I really enjoy the look, as it gives the sunscreen a more premium feel. The bottle also contains a small mixing ball, or agitator, which makes a distinctive sound when you shake it and helps thoroughly mix the formula before application. It’s a small but practical detail that makes using the product feel a little more special.
Anessa Perfect UV Sunscreen Skincare Milk - Texture & Scent
It has a milky texture, but it feels lightweight on the skin and doesn’t leave a white cast. Instead, it leaves a delicate moisturizing yet velvety layer that makes the skin feel smooth. It can also work well as both a sunscreen and a makeup primer.
P.S. If you have a warmer skin tone, you may notice that this sunscreen makes your complexion look slightly grayish. I’ve noticed this can sometimes happen with sunscreens formulated with Tinosorb filters, so it’s worth testing the product on your skin first. Even Anessa informs about that.
The fragrance isn’t too strong or unpleasant. I can detect some citrus notes, along with a slight hint of alcohol.
Is Anessa Perfect UV Sunscreen Skincare Milk Vegan/vegetarian friendly? & other claims
I couldn’t find any information confirming whether the Anessa Perfect UV Sunscreen Skincare Milk is vegan or vegetarian-friendly. However, the product is advertised as reef-conscious, and its packaging contains bio-based plastics.
Anessa Perfect UV Sunscreen Skincare Milk - UV Protection
Anessa Perfect UV Sunscreen Skincare Milk provides the highest level of UV protection under the Japanese rating system, with SPF 50+ and PA++++.
Anessa Perfect UV Sunscreen Skincare Milk - Water-resistance
Anessa Perfect UV Sunscreen Skincare Milk is water-resistant and has been tested in water for over 80 minutes. It is designed to hold up during swimming, sweating, and in humid climates, thanks in part to Shiseido’s Auto Booster Technology.

Dimethicone is a silicone-based polymer that helps smooth and soften the skin while creating a protective barrier that reduces moisture loss. Water is typically listed in cosmetic products as "Aqua" or "Eau". It acts as a solvent, but it is not the same as ordinary drinking water. In skincare products, water must meet strict purity standards to ensure it is free from impurities, including minerals, microorganisms, and other contaminants. In most formulations, water makes up the largest proportion of the product. Zinc Oxide is best known as a mineral UV filter, but it has several other uses in cosmetics. As a sunscreen ingredient, it helps protect the skin from UVA I, UVA II, and UVB radiation. It can leave a white cast on the skin, although nano Zinc Oxide generally produces less visible whitening because of its smaller particle size. Zinc Oxide is also used as a pigment and has antimicrobial properties, which is why it can be found in some products formulated for blemish-prone skin. It can also function as a skin protectant and viscosity-modifying ingredient. Zinc is sometimes used as an oral supplement, including in some approaches to acne management, but supplementation should be discussed with a healthcare professional first. Excessive zinc intake can cause adverse effects and interfere with the absorption of other minerals.
Ethanol is nothing else than alcohol. It is a widely discussed ingredient in skincare. Alcohol can be both beneficial and problematic for the skin - as with many ingredients, the dose makes the poison. Alcohol is a powerful solvent, which means it can help active ingredients penetrate the skin more effectively. However, this effect comes with a cost: it may cause some irritation. Some substances can only be dissolved in alcohol, making it an important ingredient in certain formulations. Ethanol also has antibacterial properties and can work as a preservative by preventing the growth of microorganisms in a product. However, it has some downsides too - it can dry out the skin, especially when used in high concentrations. Sensitive skin types are usually not the biggest fans of this ingredient. Diisopropyl Sebacate is a common emollient used in sunscreens to help create a lightweight, pleasant texture. It's also frequently found in lip products.
Isododecane is an emollient that helps leave a smooth, lightweight film on the skin. It also improves the spreadability and application of the product. Octocrylene is a chemical UV filter used in sunscreens. It helps protect the skin from UVB (280–315 nm) and UVA II (315–340 nm) radiation, with an absorption peak around 304 nm. It is not the most photostable UV filter, so it is often combined with other sunscreen filters to improve the overall stability and effectiveness of the formula. Ethylhexyl Salicylate, also known as Octisalate, is a UV filter commonly used in sunscreens. It is an organic (chemical) sunscreen ingredient that helps protect the skin from UVB radiation (280–320 nm). Its absorption peak is around 306 nm, meaning it provides effective UVB protection but is considered a weaker UV filter compared to some newer-generation sunscreen agents.
C12-15 Alkyl Benzoate is an emollient that helps soften and smooth the skin. It forms a lightweight, non-greasy feel and can help reduce transepidermal water loss (TEWL). It is also commonly used in sunscreen formulas because it helps improve the spreadability and sensory feel of UV filters. PEG/PPG-9/2 Dimethyl Ether is a synthetic polymer used as a skin-conditioning ingredient in cosmetic formulations. Zea Mays (Corn) Starch is a fine plant-derived powder obtained from corn. It can be used as a thickening and absorbent ingredient in cosmetic formulations, helping to improve the texture and consistency of the product. Talc is a naturally occurring mineral commonly used in makeup and cosmetic products. It can absorb excess sebum and help reduce shine while also improving the texture and spreadability of a formula, making application smoother.
Silica is a mineral-derived ingredient widely used in both makeup and skincare. It can absorb excess sebum, helping to reduce shine and create a more matte finish. It can also be used as a thickening or texture-modifying agent in cosmetic formulations. Isopropyl Myristate is a dry emollient that leaves the skin feeling soft and velvety. It helps reduce moisture loss by creating a delicate film on the skin's surface. It also improves the texture of a product, making it feel less sticky. In hair care products, it can help add shine to the hair. However, it may not be suitable for everyone, as it has a relatively high comedogenic potential. Diethylamino Hydroxybenzoyl Hexyl Benzoate, also known as Uvinul A Plus, is a highly photostable organic UVA filter commonly used in modern sunscreens. It protects the skin against UVA radiation (320–400 nm), with peak absorption at approximately 354 nm.
Titanium Dioxide (CI 77891) is a mineral UV filter and pigment widely used in sunscreens and cosmetics. As a UV filter, it primarily protects the skin from UVB and UVA II radiation, with more limited protection in the UVA I range. Its white color can leave a visible white cast on the skin, although nano-sized Titanium Dioxide particles generally produce much less visible whitening. Titanium Dioxide also functions as a white pigment and opacifying agent, which is why it is widely used in makeup and skincare products. For people prone to melasma and hyperpigmentation, protection from visible light can also be important. However, this benefit is mainly associated with tinted sunscreens containing pigments such as iron oxides rather than the white cast created by Titanium Dioxide itself. PEG-9 Polydimethylsiloxyethyl Dimethicone is a silicone-based emulsifier used to help stabilize and blend ingredients in cosmetic formulations.
Dextrin Palmitate is a gelling and binding ingredient used in cosmetic formulations to help stabilize textures, improve consistency, and enhance the sensory properties of products. Glycerin, also known as Glycerol, is a humectant that helps attract and retain moisture in the skin. Depending on the product, it can be derived from natural sources or produced synthetically. It helps protect the skin from TEWL (transepidermal water loss), a natural process in which water evaporates from the skin's surface. Glycerin is one of the components of the NMF (Natural Moisturizing Factor), which plays an important role in maintaining skin hydration. It is also widely used in hair care products due to its moisturizing properties. Glycerin is generally considered non-comedogenic and is unlikely to clog pores. Rather than irritating the skin, it can help support the skin barrier and reduce the feeling of dryness and irritation.
Homosalate is a UV filter used in sunscreens. It primarily helps protect the skin from UVB radiation (295–315 nm), with an absorption peak around 306 nm. It is a relatively weak and less photostable UVB filter, which is why it is often combined with other sunscreen ingredients, such as Avobenzone, to provide broader and more effective UV protection. Ethylhexyl Triazone, also known as Uvinul T 150, is a highly effective organic UV filter commonly used in modern sunscreens. It provides broad UVB protection (280–320 nm), with a peak absorption at approximately 314 nm. It is one of the most powerful UVB filters available, offering high protection at relatively low concentrations.
Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine is a difficult name to remember, which is why it is more commonly known as Tinosorb S. It is a newer-generation UV filter and is considered one of the most effective and photostable sunscreen ingredients available. Tinosorb S is an organic (chemical) UV filter that provides broad-spectrum protection against both UVA (315–400 nm) and UVB (280–315 nm) rays. It has a high absorption capacity across a wide range of the UV spectrum, making it highly effective at protecting the skin from UV-induced damage. One of its greatest advantages is its excellent photostability. Unlike some older UV filters, Tinosorb S remains stable when exposed to sunlight. It can also help stabilize other UV filters in a sunscreen formula, reducing their photodegradation and improving the overall stability and effectiveness of the product. Disteardimonium Hectorite is a thickening and stabilizing ingredient derived from hectorite clay. It helps improve the texture and consistency of cosmetic formulations, giving the skin a smooth, soft-focus appearance. In sunscreen formulas, it can also help stabilize UV filters and improve the overall performance of the product.
PEG-10 Dimethicone is a silicone-based ingredient commonly used in skincare as an emulsifier, although it can also have mild moisturizing and skin-conditioning properties. Many people are wary of silicones, but the silicones used in cosmetic products are subject to strict safety regulations. In skincare, silicones can provide several benefits: they improve spreadability, give formulas a smoother and more elegant texture, and can help form a protective film on the skin and hair. Isostearic Acid is a fatty acid that can function as a surfactant and emulsifier in cosmetic formulations. Triethoxycaprylylsilane is a silicone-based ingredient used to coat and improve the dispersion of mineral UV filters and pigments. It can also improve the spreadability and texture of cosmetic formulations.
Polyglyceryl-6 Polyricinoleate is an emulsifier commonly used to stabilize cosmetic formulations. It can also be used in products containing mineral UV filters and pigments, helping to disperse and evenly distribute these ingredients. Sodium Chloride is simply the common salt we use in everyday life. In skincare, it can function as a viscosity-controlling agent, helping to thicken certain formulations. It can also be used as a physical exfoliant in some products, although its relatively large and irregular crystals may be too abrasive for sensitive skin. Aluminum Hydroxide, also known as CI 77002, is a white pigment and emollient. It's used in antiperspirants because it helps absorb sweat and sebum. It can also be used as a coating ingredient for UV-protecting ingredients. Stearic Acid is a fatty acid that works as an emollient and emulsifier. It helps soften and smooth the skin while also helping to stabilize the formulation.
Trisodium EDTA is a chelating agent that binds metal ions in cosmetic formulations. This helps improve the stability of the product and can support the effectiveness of preservatives, helping to extend the product’s shelf life. PEG-6 is a nonionic surfactant that can function as an emulsifier, solvent, and wetting agent in cosmetic formulations. Fragrance (Parfum) is a blend of aromatic compounds used to give cosmetic products their scent. It can cause allergic reactions or irritation in some individuals, especially those with sensitive or reactive skin. Tocopherol is an antioxidant commonly known as Vitamin E. It is a fat-soluble vitamin that helps protect the skin from free radical damage and supports the skin's natural lipid barrier. It can also work synergistically with Vitamin C to boost antioxidant protection. Vitamin E may provide some photoprotective benefits, but it is not a substitute for sunscreen. Despite common claims, it does not act as a preservative or significantly improve scars. While some Vitamin E-rich formulations may feel too heavy for oily or acne-prone skin, Tocopherol itself is not universally considered pore-clogging.
BHT, or Butylated Hydroxytoluene, is a somewhat controversial cosmetic ingredient. This synthetic antioxidant helps protect cosmetic formulas from oxidation and extends their shelf life. Although some concerns have been raised about its safety, the Cosmetic Ingredient Review (CIR) Expert Panel has concluded that BHT is safe when used in cosmetics at the concentrations and under the conditions assessed. Butylene Glycol is a multifunctional ingredient commonly used in skincare and haircare products. It acts as a solvent and humectant, helping to dissolve ingredients while attracting moisture to the skin and hair. It can also enhance the penetration of active ingredients, improve a product's texture, and prevent formulations from drying out. Bis-Butyldimethicone Polyglyceryl-3 is a surfactant and emulsifier that helps stabilize cosmetic formulas and control their viscosity.
PEG/PPG-14/7 Dimethyl Ether is a synthetic polymer used as a skin-conditioning and moisturizing ingredient. It helps improve the skin’s hydration and leaves it feeling smooth and soft. Sodium Metabisulfite is an antioxidant and preservative used to help protect cosmetic formulations from oxidation. In hair care products, it can help prevent oxidation and maintain the stability of the formula. However, it may cause irritation or allergic reactions in some individuals, particularly those who are sensitive to sulfites. Trimethylsiloxysilicate is a silicone-based polymer with film-forming and occlusive properties. It forms a flexible, water-resistant film on the skin that can help reduce transepidermal water loss (TEWL). It is also used to improve the texture, spreadability, and wear of cosmetic formulations.
Dipotassium Glycyrrhizate is a soothing ingredient derived from licorice root (Glycyrrhiza glabra). It is known for its anti-inflammatory and skin-calming properties, making it a great choice for sensitive, irritated, or redness-prone skin. This ingredient also provides moisturizing benefits and can help support the skin barrier. Thanks to its ability to help reduce the appearance of hyperpigmentation and dark spots, Dipotassium Glycyrrhizate is often used in products targeting uneven skin tone. Its gentle nature makes it suitable for most skin types, including sensitive skin.
Camellia Sinensis (Green Tea) Leaf Extract is a powerful antioxidant that helps protect the skin from free radicals and oxidative stress. Green tea contains many beneficial compounds, including catechins such as EGCG, EGC, EC, and CG, as well as flavonoids, amino acids, vitamin C, and minerals. It has antioxidant and soothing properties and may also help support acne-prone skin thanks to its antimicrobial activity. Green tea extract is generally suitable for all skin types and can be a useful addition to a skincare routine alongside sunscreen, helping to provide additional antioxidant protection against environmental stressors. Potentilla Erecta Root Extract is an astringent ingredient rich in tannins. These compounds can help reduce excess oil and create a slightly drying effect on the skin. Potentilla erecta has traditionally been used for its astringent and soothing properties.
Citrus Unshiu (Satsuma Mandarin) Peel Extract is a source of antioxidants, including beta-carotene. It has antioxidant properties and may help brighten the skin. Sodium Acetylated Hyaluronate is a modified form of Sodium Hyaluronate with moisturizing and skin-conditioning properties. It helps increase skin hydration, improve its suppleness and elasticity, and reduce transepidermal water loss (TEWL). Synthetic Fluorphlogopite is a synthetic alternative to naturally occurring mica. It is used in cosmetics for its light-reflecting properties and can help create a smooth, silky texture and enhance the appearance of pigments. It is also often used to create a more delicate, refined shimmer than natural mica. Many brands choose Synthetic Fluorphlogopite as an alternative to natural mica because it offers consistent quality and purity. Lauryl Betaine is a mild surfactant that helps create foam. It also has antistatic properties and can function as an emulsifier in cosmetic formulations.
Soluble Collagen is a protein commonly used in skincare for its moisturizing and film-forming properties. When applied to the skin, it can form a water-binding film that helps improve hydration and reduce transepidermal water loss (TEWL). Although collagen is an important structural protein in the skin, applying collagen topically does not directly increase the skin’s own collagen production. Instead, soluble collagen mainly works at the skin’s surface, helping to keep it hydrated and smooth. Collagen used in cosmetics is generally derived from animal sources, such as fish, bovine, or porcine tissue, so it is typically not considered vegan and may not be cruelty-free depending on the sourcing and manufacturing process. Phenoxyethanol is a preservative that is often unfairly demonized. In reality, it is generally well tolerated by the skin at the concentrations used in cosmetics and also has antimicrobial properties.
Sodium Benzoate is a preservative commonly used to help prevent the growth of bacteria, yeast, and mold in cosmetic formulations. Citronellol is a scent ingredient. It adds a rose/floral scent to the product. It can be sensitizing. Geraniol is a fragrance component that provides a floral scent. It can act as a skin sensitizer and may cause irritation or allergic reactions in some individuals. Hexyl Cinnamal is an aromatic aldehyde that naturally occurs in chamomile. It adds a jasmine-like, floral scent to the product but can be sensitizing for some people. Limonene is a fragrance ingredient that gives products a fresh, citrusy scent reminiscent of lemons or oranges. It may also enhance the penetration of other substances into the skin, but it can be irritating or sensitizing, especially for sensitive skin. Linalool is a fragrance ingredient that gives products a floral scent. It can also be a potential skin sensitizer, especially for people with sensitive skin.
How to use Anessa Perfect UV Sunscreen Skincare Milk?
Before using the Anessa Perfect UV Sunscreen Skincare Milk, make sure to shake the bottle well to thoroughly mix the formula. Apply it as the final step of your morning skincare routine, before makeup.
I recommend using the two-finger method: squeeze two strips of sunscreen along your index and middle fingers to help ensure adequate coverage for your face and neck. Reapply regularly, especially when you’re outdoors, sweating, or exposed to water, as sunscreen can gradually wear off or migrate on the skin.
Although this sunscreen is water-resistant for up to 80 minutes, regular reapplication is still important to maintain adequate protection.
How does Anessa Perfect UV Sunscreen Skincare Milk work?
I’m genuinely surprised by this formula. I picked it up at Olive Young because I was able to get the smaller version. I have a long history of not enjoying Japanese sunscreens because their high alcohol content can be quite drying on my skin, but somehow, Anessa has become another Japanese sunscreen I really enjoy, along with Nivea and Biore.
I hadn’t tried Shiseido’s sunscreens before, even though the brand is easy to find where I live and I regularly shop for other Shiseido products. For example, Shiseido’s Microliner Ink is probably the only thin eyeliner that works perfectly for my eyes while also offering the cool-toned brown shade I like. But back to Anessa.
I already knew that Anessa was a huge sunscreen brand. When you look at Japanese sunscreens, some of the major names that come to mind are Biore (Kao), Nivea (a joint venture between Beiersdorf and Kao), Allie (Kanebo), Skin Aqua (Rohto), and Anessa (Shiseido). My main problem with Anessa was choosing the right product from such a large range.
The Anessa Perfect UV Sunscreen Skincare Milk is one of the brand’s classic formulas, but that definitely doesn’t mean it’s a bad option. In fact, I think it’s a great place to start if you want to try Anessa.
What I particularly like is that it works as both a sunscreen and a makeup primer. It leaves a moisturizing yet velvety layer on the skin, and my foundation adheres really well to it and seems to last longer throughout the day.
The Auto Booster Technology is another feature I really appreciate. The idea is that the UV-protective film becomes more resistant when exposed to factors such as sweat and water, which is especially useful during summer. I live in a humid climate, so sunscreens designed to withstand sweating and humidity can make a huge difference. Nobody wants their sunscreen disappearing from their face the moment they start sweating.
The formula feels moisturizing, although I’m not sure how it would perform on very dry skin. On my oily skin, however, it’s a great match. Despite my usual concerns about alcohol in Japanese sunscreens, my skin tolerated the formula very well. It doesn’t leave a noticeable white cast, doesn’t feel heavy, and overall feels surprisingly comfortable on the skin.
Skin Compability of Anessa Perfect UV Sunscreen Skincare Milk
While some websites recommend Anessa Perfect UV Sunscreen Skincare Milk for all skin types, I agree with Watsons and would recommend it primarily for oily, combination, and normal skin. For dry skin, Anessa Moisture Perfect UV Sunscreen Skincare Gel may be a better option. If you have sensitive skin, Anessa Perfect UV Sunscreen Mild Milk would likely be a more suitable choice.

Anessa Perfect UV Sunscreen Skincare Milk - Alternatives
If you can’t find the Anessa Perfect UV Sunscreen Skincare Milk or you’re looking for an alternative, you might want to try Kanebo Allie Chrono Beauty Gel UV EX*. It has a gel texture, but it also focuses on hydration and strong UV protection, making it a good alternative to Anessa.
Bioré UV Aqua Rich Watery Essence* is another popular option. It’s loved by many people and is a more budget-friendly choice compared with Anessa, which is considered a premium sunscreen brand.
Where to buy Anessa Perfect UV Sunscreen Skincare Milk & how much does it cost?
I bought the 20 ml mini version of the Anessa Perfect UV Sunscreen Skincare Milk at Olive Young*, but the regular price of this sunscreen is around $15 for a smaller size, so I’d recommend checking it out at YesStyle. The full-size 60 ml version costs around $19 on YesStyle*, and you can use my referral code BETWEENDOTS to save an additional 2–5% on your order. On Stylevana*, it costs around $16, and you can use my code SV15BETWEEND to save on your order.
Overall, Anessa is another Japanese sunscreen that works really well for me. It provides strong UV protection without leaving my skin feeling dry or dehydrated.
