# Kiehl's vs Aēsop

Page: https://lovi.care/skincare/ca/compare/kiehl-s-vs-aesop

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

Kiehl's and Aēsop are two distinct skincare lines known for nourishing moisturizers, targeted [serums](https://lovi.care/skincare/ca/ingredients/serum), and gentle formulations. The American brand relies on dependable ingredients like [glycerin](https://lovi.care/skincare/ca/ingredients/glycerin) and squalane, while the other brand is driven by botanical and scientifically validated components. The former suits mature skin and sensitive skin best, whereas the latter suits balanced, combination, and sensitive skin. Ultimately, Kiehl's focuses on barrier-supporting properties with glycerin and squalane, while Aēsop works harmoniously to support overall skin health and resilience.

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