Serums and treatments

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

A serum delivers targeted active ingredients right where your skin needs them most. It is used every evening, and in the weekly routine. These formulas most often rely on niacinamide to reduce signs of aging and dark spots, hyaluronic acid to protect cells and support deep hydration, and vitamin C to brighten the complexion.
