# The Ordinary vs Kiehl's

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

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

The Ordinary and Kiehl's are distinct skincare brands offering [serums](https://lovi.care/skincare/ca/ingredients/serum), moisturizers, cleansers, toners, and more. The Canadian brand features [hyaluronic acid](https://lovi.care/skincare/ca/ingredients/hyaluronic-acid), [glycerin](https://lovi.care/skincare/ca/ingredients/glycerin), and squalane to suit dry skin and dry sensitive skin best, while the American brand relies on glycerin and squalane to suit mature skin and sensitive skin best. Both brands differ in their founding eras and targeted concerns, yet each utilizes science-backed ingredients to support skin health.

The Ordinary is a Canadian skincare brand founded in 2016 and owned by The Estée Lauder Companies Inc. since 2021.
