# SK-II vs Allies of Skin

Page: https://lovi.care/skincare/fr/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 France.

SK-II and Allies of Skin are two distinct skincare lines known for thoughtful moisturizers, targeted [serums](https://lovi.care/skincare/fr/ingredients/serum), and restorative treatments. The Japanese brand relies on its signature ingredient, pitera, while the other features [niacinamide](https://lovi.care/skincare/fr/ingredients/niacinamide) in advanced formulations. Both brands suit dry skin and acne-prone skin best, though they differ in their specific product offerings and targeted solutions.

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