COSRX vs Paula's Choice

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

COSRX and Paula's Choice are two distinguished skincare lines that offer thoughtfully formulated serums, moisturizers, cleansers, toners, and masks. The Korean brand is beloved for harnessing ingredients like hyaluronic acid, glycerin, and niacinamide to suit oily and sensitive skin best, while the American brand builds around hyaluronic acid, glycerin, and vitamin c to fit oily and mature skin. Both feature effective staples for acne-prone skin, dark spots, and aging, yet they differ in their foundational approaches to balancing moisture, soothing irritation, and refining pores.

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