# Kiehl's vs ISDIN

Page: https://lovi.care/skincare/it/compare/kiehl-s-vs-isdin

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

Kiehl's and ISDIN are established skincare houses that offer thoughtful daily support for a balanced complexion. The American brand is loved for its nourishing moisturizers, targeted [serums](https://lovi.care/skincare/it/ingredients/serum), soothing toners, and gentle eye products relying on dependable ingredients like [glycerin](https://lovi.care/skincare/it/ingredients/glycerin) and squalane, while the Spanish brand is known for elegant moisturizers, advanced sunscreens, restorative serums, and targeted eye products united by balanced formulas. Products from the former suit mature skin and sensitive skin best because of their gentle formulations and barrier-supporting properties, whereas offerings from the latter suit dry skin and sensitive skin best by providing gentle daily comfort and dependable protection. Ultimately, both differ primarily in their heritage and specific ingredient profiles, with the first utilizing glycerin and squalane to increase hydration and counteract oxidative stress.

Kiehl's is an American skincare brand founded in 1851 and owned by L'Oréal S.A. since 2000.
