Epidermal Growth Factor (EGF) is a protein that plays a crucial role in cell growth, proliferation, and differentiation. It binds to specific receptors on the surface of cells, triggering a series of biological processes that promote healing and tissue regeneration. EGF is naturally found in various tissues and is also produced in the laboratory for medical and cosmetic applications. In medicine, EGF is used in treatments for wounds and burns, as it helps accelerate the healing process. In the cosmetic industry, it is often included in skincare products to improve skin texture and reduce signs of aging. Its effectiveness has made it a popular ingredient in both therapeutic and beauty products.
