Kiehl's vs Bio-Oil

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

Kiehl's and Bio-Oil are two distinct skincare lines known for nourishing different complexions with targeted formulations. The American heritage brand relies on glycerin and squalane within its moisturizers, serums, toners, and eye products to suit dry and sensitive skin, while the other brand offers specialized oils that suit dry, mature, and uneven skin types best. Both brands feature standout choices for acne-prone skin, including the Calendula Herbal-Extract Toner and the Skincare Oil. Ultimately, the two options differ through the heritage brand's focus on barrier restoration and hydration versus the latter's lightweight, balanced moisture.

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