Hydrolyzed Egg Shell Membrane

What is Hydrolyzed Egg Shell Membrane?

Hydrolyzed egg shell membrane comes from the thin, fibrous layer inside chicken eggshells, naturally abundant in collagen types I, V, and X, elastin, and glycosaminoglycans like hyaluronic acid and chondroitin sulfate. Through hydrolysis, large proteins break into smaller peptides for better absorption. In cosmetics, it appears in moisturizers, serums, and creams targeting hydration and texture. It works by attracting water to the skin's surface layer, forming a protective film that locks in moisture while providing emollient effects to soften and smooth the skin barrier. This dual humectant and conditioning role helps maintain skin's natural suppleness without greasiness, fitting well in daily routines for balanced hydration.
