COSRX vs RoC

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

COSRX and RoC are established skincare brands offering expertly formulated serums, moisturizers, cleansers, and more. The Korean line thoughtfully incorporates hyaluronic acid, glycerin, and niacinamide to suit acne-prone and oily skin best, while the French label relies on glycerin and retinol to care for mature and dry skin. Through daily application, both utilize their key ingredients to increase skin hydration and barrier function, though they differ as the former focuses on balancing and clarifying components for blemishes and dark spots, whereas the latter addresses aging and dryness with collagen-boosting retinol.

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