Eggshell Membrane delivers collagen, elastin, desmosine and isodesmosine (amino acids responsible for elastin’s elastic properties), and glycosaminoglycans (including glucosamine and chondroitin) deep within the skin. This 100% natural ingredient is clinically-proven to help reduce fine lines and wrinkles, hydrate and moisture-balance the skin, improve skin tone and resilience, as well as texture and feel, and protect skin from free radicals and oxidative damage and stress associated with aging. We use BiovaDerm hydrolyzed eggshell membrane, which is manufactured in Iowa, USA. BiovaDerm is a registered trademark of Biova LLC.
