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 two celebrated skincare lines designed to nurture dry and acne-prone skin. The Japanese heritage brand relies on pitera within its nourishing serums, moisturizers, masks, and toners to gently soothe delicate complexions and refine pores. Meanwhile, Allies of Skin utilizes powerhouse ingredients like niacinamide across its luxurious moisturizers, potent serums, and targeted eye products to address signs of aging and hyperpigmentation. While both excel at restoring a balanced appearance, they differ through their distinct formulations and foundational philosophies.

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