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

COSRX and SEYOUL are respected skincare brands that offer distinct approaches to daily care. COSRX is a Korean skincare brand founded in 2013 and owned by Amorepacific Group since 2024, beloved for its thoughtful array of serums, moisturizers, cleansers, masks, and more, all formulated with trusted ingredients like hyaluronic acid, glycerin, and niacinamide. Meanwhile, the second brand is loved for its nourishing masks and delicate formulas. The first suits oily skin and acne-prone skin best because its active components balance excess oil and soothe irritation, while both suit dry, oily, and combination skin best.
