What Is Hydrolyzed Egg Shell Membrane?
Hydrolyzed egg shell membrane is primarily known for its hydration-enhancing (humectant) properties in skin care formulations; however, emerging research indicates its benefits may extend beyond moisture retention. Derived from the thin membrane lining the inside of an egg shell, this ingredient undergoes hydrolysis to become water-soluble. Of note, hydrolyzed egg shell membrane is known to be a rich source of glycosaminoglycans and amino acids, which play a role in replenishing and restoring skin to a healthier state.
In the realm of anti-aging, studies have shown hydrolyzed egg shell membrane helps support elastin and collagen and hence, has value as an anti-wrinkle agent. (Its effectiveness in this regard is considered mild but measurable.) Recent studies suggest that oral supplementation of hydrolyzed egg shell membrane may also contribute to skin improvements such as visible reduction of fine lines and wrinkles.
As a part of sustainable production practices, suppliers of this ingredient often tout repurposing upcycled egg shells from the food industry. Note: Hydrolyzed egg shell membrane may also be spelled hydrolyzed eggshell membrane.
