What it is
Hydrolyzed collagen is a protein fragment used topically in skincare and haircare as a humectant and film-former. On skin it draws water into the surface and improves the look of smoothness; on hair it deposits a temporary conditioning film along the cuticle. Topical collagen does not replenish dermal collagen — molecular weight is far too high to penetrate. No major conflicts.
Pregnancy and breastfeeding
Safe
