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 known for their thoughtful formulations and dedicated followings. The Korean brand is recognized for its serums, moisturizers, cleansers, and masks featuring hyaluronic acid, glycerin, and niacinamide, which suit acne-prone and oily acne-prone skin best. Meanwhile, the other brand is celebrated for its moisturizers and gentle cleansers that suit dry, balanced, and sensitive skin types. While both offer targeted options for specific concerns, they differ in their core ingredients and ideal skin types.
