What is EGF epidermal growth factor?

EGF exists in human epithelial cells, which can stimulate the growth of epithelial cells and endothelial cells, make new epidermal cells grow continuously, push the dead cortex off gradually, keep the skin tender and smooth, promote the metabolism of various skin cells, enhance the absorption of nutrients by cells, promote the synthesis of collagen and collagenase, secrete collagen substances, hyaluronic acid and glycoprotein, regulate collagen fibers, and have the functions of moistening skin, enhancing skin elasticity, reducing skin wrinkles and preventing skin aging. According to EGF's good physiological characteristics, especially its activation on basal cells of skin epidermis, biologists have boldly tried to apply it to beauty cosmetics in recent years. This kind of biological cosmetics is essentially different from traditional cosmetics. In a sense, traditional cosmetics play a more decorative role and cannot fundamentally solve skin problems. The application of EGF in beauty cosmetics is to repair and adjust cells at the molecular level according to the physiological structure of human skin, and to improve or update their functions such as composition and metabolism. At present, EGF has been used as the raw material of cosmetics for moisturizing, anti-wrinkle, whitening, skin rejuvenation and facial plastic surgery, which can promote the growth of skin cells, adjust the balance of pigments in cells, and then create the best structure and state of skin, making skin cells younger. Many skin problems, such as laxity, aging, wrinkles, dullness, roughness, pigmentation and acne, will be gradually improved, thus achieving the purpose of protecting the skin.
