Hydrolyzed Elastin description

Hydrolyzed elastin is elastin that’s been broken down into amino acids through the process of hydrolysis. In skin care, hydrolyzed elastin’s humectant properties are used to help hydrate skin through the attraction of moisture to skin’s surface. Elastin’s naturally occurring in the body, working hand-in-hand with collagen to promote a firm, tight appearance. Elastin’s true talent comes in the form of physical resiliency, allowing skin to “bounce back” like elastic after stretching. Although hydrolyzed elastin is derived from elastin protein, it cannot function like elastin does within the body, as its molecules are far too large to penetrate beyond skin’s surface when applied topically. Unlike collagen, it’s much harder to stimulate the regeneration of elastin within the extracellular matrix (area of skin between the epidermis and dermis). That’s why it’s important to maintain the health of the elastin already present in skin through the consistent usage of sun safe practices, such as the application of a broad-spectrum SPF 30+ sunscreen every day. Hydrolyzed elastin is usually sourced from the skin of fish, which is why it can also be referred to as “marine elastin.” The Cosmetic Ingredient Review Expert Panel reviewed hydrolyzed elastin and deemed it safe for use in cosmetics. Typical usage levels for hydrolyzed elastin range from 1–5%.
