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 two distinct skincare lines known for expertly formulated serums, moisturizers, cleansers, masks, and eye products. The Korean brand founded in 2013 and owned by Amorepacific Group since 2024 thoughtfully incorporates hyaluronic acid, glycerin, and niacinamide to suit acne-prone skin and oily skin best, while the other brand is loved for luxurious moisturizers, potent serums, and targeted eye products formulated with powerhouse ingredients like niacinamide to suit dry skin and acne-prone skin best. Through daily application, the first brand uses its key ingredients to lengthen toxin duration and reduce cell damage, significantly increase skin hydration and barrier function, and significantly decrease hyperpigmentation and reduce skin aging, whereas Allies of Skin relies on niacinamide to improve skin aging signs and decrease hyperpigmentation to restore a clear, balanced complexion. They differ primarily in their specific target skin types and overall luxury formulations, offering distinct options for personalized routines.
