EGF stands for Epidermal Growth Factor. Growth factors are cellular activators: they are signal molecules that communicate with cells, sending a message to repair, rejuvenate, or proliferate. Hundreds of different growth factors control the more than 300 cell types in humans. They’re the crucial foremen on the construction site that is your body’s development, and they work at full capacity for years. From birth until adulthood, our bodies manufacture copious amounts of various growth factors that affect the growth of everything from bones to organs to nerves to skin. But when we reach maturity, production diminishes. As a result, cell turnover and repair slows, eventually affecting our health and appearance. In fact, our skin gets thinner by 1% each year after we turn 20, and five years after menopause, our skin becomes 30% thinner.Since 1986, medical research into growth factors has exploded. Huge breakthroughs include life-saving treatments such as the use of G-CSF, a growth factor that induces the production of white blood cells after chemotherapy. EGF, or epidermal growth factor, helps burn victims grow new skin and speed wound recovery. But EGF may also be used to replenish the body’s own supply, which diminishes with age. EGF application stimulates the body’s own skin cells to proliferate, increasing skin turnover and radiance while slowing the aging process. It boosts production of collagen and elastin, the skin’s bouncy scaffolding, increasing tone and elasticity. It boosts the skin’s capacity to store water and reduce water loss. The result is healthier, denser, more hydrated,  younger-looking skin.
