Epidermal Growth Factor was first discovered by Stanley Cohen, an American Biochemist at Vanderbilt University. He worked together with Rita Levi-Montalcini and both of them received the Nobel Prize for their work in 1986. EGF’s are small polypeptides of 53 amino acids that behave as cell-signaling protein molecules to the skin matrix (our skin’s first line of defense against aging) to stimulate epithelial cell growth and reproduction, collagen synthesis, and blood-vessel formation. Epidermal Growth Factor increases cell renewal and assists the skin in wound healing and stimulates the skin's ability to repair itself from the damaging rays of the sun. It provides exceptional benefits in skin regeneration, offering the ability to plump and firm skin to reduce existing wrinkles.
