COSRX vs Allies of Skin

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

COSRX and Allies of Skin are skincare brands offering thoughtful arrays of serums, moisturizers, cleansers, masks, and eye products. COSRX features trusted ingredients like hyaluronic acid, glycerin, and niacinamide, suiting oily and acne-prone skin best, while Allies of Skin is built around potent ingredients like niacinamide to suit dry and mature skin best. Both brands differ because the first balances excess oil and soothes irritation with standout solutions like the Advanced Snail Mucin Gel Cleanser, the Full Fit Propolis Synergy Toner, and the Centella Water Alcohol-Free Toner, whereas the second offers rich hydration and targeted nourishment through formulations like the Molecular Saviour Probiotics Treatment Mist, the Peptides & Antioxidants Firming Daily Treatment, and the Peptides & Omegas Firming Eye Cream.

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