Dermatologists recommend retinol and peptides to boost skin collagen

Dermatologists state that topical collagen alone is not effective for boosting skin collagen due to molecule size. Instead, ingredients like retinol, peptides, and vitamin C are recommended as they stimulate the skin's own collagen production, leading to firmer, plumper skin. While hydrolyzed and marine collagen offer surface hydration, combining them with active ingredients or using in-office treatments provides more significant collagen-boosting benefits.
