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 specialized serums, moisturizers, cleansers, and eye products. The Korean line utilizes hyaluronic acid, glycerin, and niacinamide to suit oily and sensitive skin, while the French line features glycerin and potent retinol to serve acne-prone and mature skin. Both manufacturers strengthen moisture barriers, though they differ as the former relies on snail mucin and propolis for soothing and hydrating, and the latter employs high-strength retinol for smoothing fine wrinkles.

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