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 celebrated skincare lines known for their distinct approaches to everyday wellness. The Korean skincare brand features expertly formulated serums, moisturizers, cleansers, and masks that incorporate hyaluronic acid, glycerin, and niacinamide to suit acne-prone and oily skin best, while the alternative offers thoughtful moisturizers and gentle cleansers built on high-performing formulas that suit dry, balanced, and sensitive skin types best. These approaches differ primarily in their core ingredient profiles and targeted skin type compatibility. Through daily application, both help users achieve a balanced, radiant complexion.

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