What it is
Hydrolyzed Elastin is made by hydrolyzing elastin, a structural protein, into shorter, more soluble peptide fragments that disperse readily in the water phase of a formula. In skincare it is used as a conditioning agent that helps bind moisture and leave a soft, supple feel on the skin's surface. It often appears alongside hydrolyzed collagen in products marketed around skin softness and a smooth feel.
Safety & warnings
Hydrolyzed protein ingredients are generally well tolerated in topical use. As with other proteins, sensitive individuals could theoretically react, and source-derived sensitivities are possible. It is not a fragrance allergen and is not associated with comedogenicity at typical use levels.
Origin & sourcing
Typically animal-derived, produced by enzymatic or chemical hydrolysis of elastin protein; the specific source depends on the supplier.
Questions everyone asks
What does hydrolyzed elastin do for skin?
It works as a moisture-binding conditioning agent that helps the skin's surface feel soft and supple; it does not rebuild the skin's own elastin.
Is hydrolyzed elastin vegan?
Usually no, as elastin is typically an animal-derived structural protein; check with the brand if a plant-based or vegan formula is required.
