COSRX vs La Roche-Posay

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

COSRX and La Roche-Posay are revered skincare brands that offer expertly formulated serums, moisturizers, cleansers, and masks. The Korean brand is dearly loved for incorporating hyaluronic acid, glycerin, and niacinamide, making its products suit acne-prone and oily skin best. Conversely, the French brand features nourishing glycerin, soothing thermal water, and brightening niacinamide to suit skin with dark spots and mature skin best. While both brands harness powerful ingredients like niacinamide to decrease hyperpigmentation, the former focuses on snail mucin and propolis for clarifying care, whereas the latter relies on thermal water and vitamin C for comforting, targeted solutions.

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