Most humectant ingredients share a general approach. Collagen (Hydrolysed) is more targeted than most. Large molecules sit on surface and attract moisture; cannot penetrate dermis topically.

The scientific name is Hydrolyzed Collagen. Large molecules sit on surface and attract moisture; cannot penetrate dermis topically. This mechanism is consistent across properly formulated products, which means the real variable is concentration and delivery system.

Typical working concentration is 1–5%. Best suited to all skin types skin. Primary applications: surface hydration, plumping, conditioning.

Works well with: Hyaluronic acid, peptides.

Topical collagen doesn’t replace lost dermal collagen; peptides are better for that.
