EGF (Epidermal Growth Factor) is a naturally occurring molecule in our bodies that dramatically increases skin cell regeneration and whose important discovery warranted a 1986 Nobel Prize. As we age, our skin becomes sluggish and cell turnover decreases over 50%. Nutrex’s EGF, derived from E. coli, stimulates old skin cells to revert to a youthful, renewal pattern significantly improving overall skin quality. One reason for the overwhelming success and why it has been labeled as the “fountain of youth” is that, unlike other anti-aging ingredients, EGF causes no irritation and is immediately recognized when applied because it already exists in our bodies.
