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 Korean brand COSRX relies on key ingredients like hyaluronic acid, glycerin, and niacinamide, making its offerings suit oily and acne-prone skin best. Conversely, Trilogy is deeply loved for its gentle cleansers and high-performing moisturizers that suit dry, balanced, and sensitive skin types. While both brands feature standout products for specific concerns, they differ significantly in their ingredient philosophies and target complexions.

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