Marine Collagen sits in the humectant category, but the reason it works is specific. Hydrolysed collagen peptides from fish skin; surface moisturisation; may stimulate fibroblasts.
The scientific name is Hydrolyzed Fish Collagen. Hydrolysed collagen peptides from fish skin; surface moisturisation; may stimulate fibroblasts. This mechanism is consistent across properly formulated products, which means the real variable is concentration and delivery system.
Typical working concentration is 0.1–5%. Best suited to all skin types skin. Primary applications: surface hydration, film-forming, skin conditioning.
Works well with: Hyaluronic acid, peptides.
Smaller molecule than bovine; better bioavailability claims; topical cannot replace dermal collagen.
