# Kiehl's vs Simple

Page: https://lovi.care/skincare/sg/compare/kiehl-s-vs-simple

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

Kiehl's and Simple are established skincare brands known for offering nourishing moisturizers, soothing toners, and gentle cleansers that cater to different complexion needs. The American brand utilizes key ingredients like [glycerin](https://lovi.care/skincare/sg/ingredients/glycerin) and squalane in its targeted [serums](https://lovi.care/skincare/sg/ingredients/serum) and rich moisturizers, making it best suited for dry and mature skin to address moisture loss and barrier resilience. Meanwhile, the British brand relies on nourishing [niacinamide](https://lovi.care/skincare/sg/ingredients/niacinamide) and glycerin within its makeup removers and gentle formulas, offering a comforting routine that suits oily, acne-prone, and sensitive skin. Ultimately, the two differ in their core ingredient profiles and ideal skin types, giving users distinct pathways to hydration and balance.

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