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 skincare brands known for expertly formulated serums, moisturizers, cleansers, and more. The Korean brand features hyaluronic acid, glycerin, and niacinamide to suit acne-prone and oily skin, while the French brand enriches its products with glycerin and retinol to care best for mature skin and skin with dark spots. Through daily application, both use their key ingredients to significantly increase skin hydration and barrier function. They differ because the former brand lengthens toxin duration, reduces cell damage, and decreases hyperpigmentation, whereas the latter reduces fine wrinkles and increases collagen.

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