Lately, I've tested three different K-beauty moisturizers - Cosrx Balancium Comfort Ceramide Cream, Cosrx Balancium B5 D-Panthenol Cream and Illiyoon Ceramide Ato Cure Balm. What do these three products have in common? They are all products that should strength your skin barrier and soothe your skin. Which one is the best?
