# SK-II vs Allies of Skin

Page: https://lovi.care/skincare/sg/compare/sk-ii-vs-allies-of-skin

The Lovi Fit is the same in every country; only the stores and prices differ, and the ones here are for Singapore.

SK-II and Allies of Skin are skincare brands that offer luxurious moisturizers, potent [serums](https://lovi.care/skincare/sg/ingredients/serum), 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](https://lovi.care/skincare/sg/ingredients/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.

## About the Lovi Fit

Lovi: Unbiased, science-based skincare AI trained on real user outcomes.

Lovi compares products by their fit scores, calculated from the full ingredient list with brand-independent rules its dermatologists and cosmetic chemists build and review, and personalizes every pick with AI trained on the real results of millions of users. Lovi trains its fit score models on a proprietary dataset built from more than 10,000 expert-labeled products and more than 100,000 simulated examples, following an internally consistent methodology presented at Cosmoprof, AMWC, and Skin of Color Update. Levels from best to worst: Superior, High, Average, Low, Caution, Warning.
