COSRX vs Kiehl's
COSRX and Kiehl's are two esteemed skincare brands offering distinct approaches to daily routines, with the Korean brand founded in 2013 and the American brand established in 1851. Enthusiasts adore the former for its thoughtfully formulated serums, moisturizers, cleansers, and masks featuring hyaluronic acid, glycerin, and niacinamide, which suit acne-prone and oily acne-prone skin best, while the latter is beloved for its trusted moisturizers, serums, toners, and eye products containing glycerin and squalane, which suit dry skin and skin with dark spots best. These brands differ primarily in their heritage and targeted formulations, as the first addresses specific blemishes effectively through snail mucin, propolis, and centella, whereas the second relies on moisture-retaining and brightening properties like calendula and squalane.
COSRX is a Korean skincare brand founded in 2013 and owned by Amorepacific Group since 2024.
