COSRX vs the purest

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

COSRX and the purest are two well-regarded skincare names cherished for their gentle moisturizers, serums, cleansers, and masks. The former is a 2013 Korean brand owned by Amorepacific Group, known for ingredients like hyaluronic acid, glycerin, and niacinamide, which suit oily and acne-prone skin best by balancing excess oil and soothing irritation. Meanwhile, the latter is deeply cherished for thoughtfully composed formulas that suit sensitive, dry, and combination skin best, while offering reliable daily support for acne-prone skin. Ultimately, the two differ in their primary skin type focus and active ingredients, with the first brand relying on targeted compounds for oil control and the second brand earning praise through consistent, understated performance.

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