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

Good Molecules and Medik8 are skincare brands that offer serums, moisturizers, eye products, and more, formulated with key ingredients like hyaluronic acid. Good Molecules is an American brand founded in 2019 and owned by Beautylish, Inc., while Medik8 is a British brand founded in 2009 and owned by L'Oréal Groupe since 2025. Both suit dry skin best, though the American brand also suits acne-prone skin and the British brand also suits dry sensitive skin. They differ in their specific formulations, with glycerin in the American brand improving hydration and restoring barrier function, and both utilizing hyaluronic acid to lengthen the effect of wrinkle-reducing toxins.
