COSRX vs Rilastil

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

COSRX and Rilastil are two distinct skincare brands offering dedicated solutions for diverse complexions. COSRX is beloved for its thoughtful array of serums, moisturizers, cleansers, masks, and more, all formulated with trusted ingredients like hyaluronic acid, glycerin, and niacinamide, while the other is warmly loved for its targeted serums and meticulously balanced formulas. The first brand suits oily skin and acne-prone skin best because its active components balance excess oil and soothe irritation, whereas Rilastil suits sensitive, dry, and mature skin types best due to its gentle yet deeply nourishing approach. Ultimately, they differ through their core formulations, with the Korean line focusing on active components for blemish care and the latter restoring daily comfort and enhancing natural resilience.

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