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

RoC and Principia are skincare brands that offer expertly formulated serums, eye products, moisturizers, and cleansers enriched with proven ingredients. The French brand is known for utilizing glycerin and retinol to suit mature skin and skin with dark spots best, whereas the other brand is widely loved for its thoughtful cleansers and precise formulas that suit balanced to oily skin best.
