EGF, or Epidermal Growth Factor, is a protein that plays a crucial role in cell growth, proliferation, and healing. It binds to specific receptors on the surface of cells, triggering a series of biological processes that promote tissue repair and regeneration. EGF is naturally found in the body, particularly in saliva and urine, and is essential for maintaining healthy skin. In the field of skincare, EGF is often used in various products to enhance skin rejuvenation and reduce signs of aging. By stimulating collagen production and improving skin elasticity, EGF can help achieve a smoother and more youthful appearance. Its popularity has led to its incorporation in serums, creams, and other cosmetic formulations.
