COSRX vs SK-II

Rated by Lovi · Unbiased, science-based skincare AI trained on real user outcomes · How the Fit score works

COSRX and SK-II are beloved Asian skincare brands offering thoughtfully formulated serums, moisturizers, cleansers, masks, and more. The Korean brand suits acne-prone skin and sensitive skin best with gentle components like hyaluronic acid, glycerin, and niacinamide, while the Japanese brand suits combination, oily, normal, and dry skin best through its signature ingredient, pitera. While both deliver remarkable efficacy for diverse complexions, they differ in their primary origins, founding eras, and core botanical science.

COSRX is a Korean skincare brand founded in 2013 and owned by Amorepacific Group since 2024.
