# The INKEY List vs SK-II

Page: https://lovi.care/skincare/es/compare/the-inkey-list-vs-sk-ii

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

The INKEY List and SK-II are distinct skincare lines founded in the United Kingdom and Japan, respectively. The British brand offers targeted moisturizers, [serums](https://lovi.care/skincare/es/ingredients/serum), toners, and eye products built around [glycerin](https://lovi.care/skincare/es/ingredients/glycerin), suiting sensitive and combination skin best. Conversely, the Japanese house is known for luxurious moisturizers, potent serums, rejuvenating masks, and clarifying toners powered by its signature ingredient, pitera, which serve combination, oily, normal, and dry complexions. While both collections feature specialized formulas for acne-prone skin, dark spots, and aging, they differ fundamentally in their botanical and molecular approaches to barrier repair and refinement.

The INKEY List is a British skincare brand founded in 2018 and owned by Brand Evangelists for Beauty Limited.
