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

COSRX and Allies of Skin are notable skincare lines offering targeted solutions for diverse complexions. The Korean brand, founded in 2013 and owned by Amorepacific Group since 2024, is beloved for its thoughtful array of serums, moisturizers, cleansers, and masks that harness key ingredients like hyaluronic acid, glycerin, and niacinamide to suit oily and sensitive skin best. Conversely, Allies of Skin is deeply loved for its thoughtful range of moisturizers, serums, and eye products built around potent ingredients like niacinamide to suit dry and mature skin best. While both brands feature niacinamide and address dark spots, acne-prone skin, and mature skin through distinct formulations, they differ primarily in their ingredient profiles, targeted skin types, and product specializations.
