Page: https://lovi.care/skincare/de/compare/isdin-vs-dot-and-key

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

ISDIN and DOT & KEY are distinct international skincare labels offering thoughtfully formulated daily care. The Spanish house is celebrated for sophisticated moisturizers, advanced sunscreens, targeted [serums](https://lovi.care/skincare/de/ingredients/serum), and soothing eye products that suit dry and combination skin, featuring standouts like Fusion [Water](https://lovi.care/skincare/de/ingredients/water), Eryfotona Actinica, and K-Ox Eyes. Meanwhile, the Indian brand is warmly embraced for sensorially pleasing sunscreens with lightweight textures that suit balanced, combination, and normal skin, highlighted by the Watermelon Cooling Sunscreen. While both deliver protective daily solutions, they differ in their heritage and ideal skin types, with the former favoring richer, targeted formulas and the latter focusing on weightless daily essentials.

ISDIN is a Spanish skincare brand founded in 1975 and owned by Puig.
