SK-II vs Allies of Skin

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

SK-II and Allies of Skin are skincare brands that offer luxurious moisturizers, potent serums, soothing masks, refreshing toners, and eye products. Skincare enthusiasts adore SK-II for its signature pitera formulations, while the other is loved for its thoughtful range built around hardworking ingredients like niacinamide. Both brands suit dry and sensitive skin best, though the Japanese brand features deeply nourishing and gentle properties for dry skin, and the latter offers gentle yet deeply restorative formulations for uneven skin. Ultimately, they differ because the former relies on pitera to improve pore area, roughness, and redness, whereas its counterpart uses niacinamide to improve skin aging signs and decrease hyperpigmentation.

SK-II is a Japanese skincare brand founded in 1980 and owned by The Procter & Gamble Company since 1991.
