COSRX vs Trilogy

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

COSRX and Trilogy are two distinct skincare lines offering thoughtful serums, moisturizers, cleansers, and masks. The former brand utilizes hyaluronic acid, glycerin, and niacinamide to suit oily and sensitive skin best, while the latter brand relies on high-performing formulas to suit dry, balanced, and sensitive skin types. Ultimately, both offer tailored options that differ in their foundational ingredients and targeted moisture balances.

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