# ISDIN vs the purest

Page: https://lovi.care/skincare/ca/compare/isdin-vs-the-purest

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

ISDIN and the purest are two distinct skincare lines known for gentle moisturizers, advanced sunscreens, restorative [serums](https://lovi.care/skincare/ca/ingredients/serum), and targeted eye products with thoughtfully balanced formulas. The Spanish brand suits dry and sensitive skin best, offering standout solutions like Fusion [Water](https://lovi.care/skincare/ca/ingredients/water) for acne-prone skin, Eryfotona Actinica for dark spots, and K-Ox Eyes for mature skin, while the other brand is also cherished for combination skin through consistent, understated performance. Both deliver reliable daily support that maintains a healthy complexion, yet they differ as ISDIN is a Puig-owned house founded in 1975 with specialized scientific remedies.

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