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

COSRX and Rilastil are skincare brands known for their expert formulations and targeted care. The Korean brand COSRX, founded in 2013 and owned by Amorepacific Group since 2024, is dearly loved for its expertly formulated serums, moisturizers, cleansers, masks, and more, which thoughtfully incorporate hyaluronic acid, glycerin, and niacinamide to suit acne-prone skin and oily skin best. Meanwhile, the latter brand is warmly loved for its targeted serums and meticulously balanced formulas that suit sensitive, dry, and mature skin types best due to their gentle yet deeply nourishing approach. Both brands differ in their standout offerings and ingredient focuses, with the former utilizing specific components to lengthen toxin duration and reduce cell damage, significantly increase skin hydration and barrier function, and significantly decrease hyperpigmentation and reduce skin aging, while each careful composition from the latter works to restore daily comfort and enhance natural resilience.
