COSRX The Ceramide Skin Barrier Moisturizer
Ingredient analysis and how the ad lines read
Read on 2026-09-09
What is this product?
Buy this if you want a fragrance-free, extract-free barrier cream with an unusually complete lipid construction, and read the numbers before you buy it for the ceramides in its name. COSRX's The Ceramide Skin Barrier Moisturizer is an 80ml cream with 49 disclosed ingredients and, unusually, seven printed concentrations. It carries all five stratum corneum ceramide subclasses plus cholesterol, palmitic and stearic acid, and phytosphingosine, which is the full physiological lipid trio. But the brand's own figures put those ceramides at 5,500 ppb down to 1 ppb, while two ceramide-mimetics at positions 12 and 16 sit at 8,000 and 7,000 ppm, so the working lipid content comes from ingredients the name does not mention. Across all 49 entries there is no botanical extract, no fragrance, no acid and no drying alcohol. The notice table states 기능성 없음, no functional-cosmetic filing. No pH, no clinical test, and no container-format text appears in the archived material, and no ranking-snapshot review aggregate was supplied for this SKU.
What makes it different?
Seven printed ingredient concentrations on a category where disclosure is rare, and a lipid construction that names all five ceramide subclasses alongside cholesterol and free fatty acids while the brand's own numbers show two unnamed ceramide analogues doing the quantitative work.
