Rated by Lovi · Unbiased, science-based skincare AI trained on real user outcomes · How the Fit score works

Kiehl's and Allies of Skin are skincare brands offering nourishing moisturizers, targeted serums, and gentle eye products that rely on ingredients like glycerin, squalane, and niacinamide. Kiehl's suits mature skin and sensitive skin best through barrier-supporting formulations, while the other brand offers rich hydration tailored for dry skin and mature skin. Ultimately, the two differ in their core formulations, with the American brand featuring heritage ingredients like glycerin and squalane, and its counterpart utilizing potent actives to improve aging signs and decrease hyperpigmentation.

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