What it is & what it does
Topical Collagen mainly works as a film former and humectant at the skin surface.
WHAT IT IS: Topical Collagen mainly works as a film former and humectant at the skin surface.
HOW IT WORKS: It can improve temporary smoothness and reduce the dry, tight feel, but it does not directly replace dermal collagen because intact collagen is too large to rebuild the dermal matrix from the surface.
WHY ITS ROLE MATTERS: Protein-derived cosmetic ingredients can form a conditioning film and help improve the temporary feel of skin, hair or nails. Hydrolysis changes molecular size and thus can change how a protein ingredient behaves at the surface. It is not evidence that the protein rebuilds living tissue underneath.
A REALISTIC EXPECTATION: The most defensible claim is improved surface feel and conditioning, while deeper collagen or keratin repair requires different evidence.
