EGF

Epidermal growth factor has come to the beauty market by way of modern medicine. A polypeptide (or molecular chain of amino acids) developed to speed wound recovery, EGF stimulates skin growth at the cellular level. It may also increase collagen production, though the jury’s still out on this count. EGF’s success as a healing agent (success is a bit of an understatement actually; scientists have been awarded the Nobel Prize for this breakthrough) has led many in the beauty industry to parlay its powers in anti-aging products.
