Marine Collagen in a topical formula mainly acts as a film-forming, water-binding protein.
It can make skin feel smoother and more hydrated temporarily, but topical collagen molecules do not simply become new dermal collagen. Any true collagen-stimulation claim has to come from other actives or specific evidence.
Information approach
