# SK-II vs La Prairie

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

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 La Prairie are luxury skincare houses established in late-twentieth-century Asia and Europe, respectively. SK-II is renowned for its clarifying toners, rejuvenating masks, potent [serums](https://lovi.care/skincare/es/ingredients/serum), and luxurious moisturizers powered by pitera, while the Swiss brand is beloved for its finely crafted eye products, serums, moisturizers, and toners. The Japanese formulations suit normal, combination, oily, and dry skin best, whereas the European collections tend to favor mature and dry sensitive skin. Ultimately, the botanical science of the first choice focuses on refining pores, roughness, and redness, differing from the targeted anti-aging solutions of the second.

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