# SK-II vs SEYOUL

Page: https://lovi.care/skincare/es/compare/sk-ii-vs-seyoul

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

SK-II and SEYOUL are distinguished skincare lines that offer thoughtfully crafted preparations to care for the complexion. SK-II features luxurious moisturizers, potent [serums](https://lovi.care/skincare/es/ingredients/serum), rejuvenating masks, and clarifying toners powered by pitera, while SEYOUL is loved for its nourishing masks and delicate formulas. Both brands suit combination, oily, and dry skin best, though the Japanese brand also accommodates normal skin and features standout items like the Genoptics Ultraura Essence, Facial Treatment Essence, and Facial Treatment Clear Lotion, whereas the other brand offers the [Collagen](https://lovi.care/skincare/es/ingredients/collagen) Night Wrapping Mask. Ultimately, the former brand relies on the botanical science of pitera to improve pore area, roughness, and redness, while the latter brand cares with quiet precision.

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