Betaine

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

Betaine

Betaine deeply quenches parched skin, softens rough patches, and gently restores balance without causing irritation. It is especially well-suited for both very dry and very oily skin types, and it is most commonly found in soothing creams. This gentle ingredient fits smoothly into daily routines, working particularly well alongside glycolic acid, blended glycolic and citric acids, and bio-placenta peptides.
