Growth factors are natural proteins that act as chemical messengers in the body to control cell growth, division, healing, and repair. They attach to cell surfaces to trigger essential biological tasks like tissue renewal and collagen production. Biological Functions Cell Signaling: Tell cells when to divide, mature, or survive. Wound Healing: Help repair damaged tissue and regenerate skin or blood vessels. Natural Decline: Decrease in number as the body ages, leading to wrinkles or loss of skin firmness. Common Types EGF (Epidermal Growth Factor): Speeds up skin cell turnover and surface repair. FGF (Fibroblast Growth Factor): Supports deep structural support, including collagen and elastin. VEGF (Vascular Endothelial Growth Factor): Stimulates the formation of new blood vessels. IGF (Insulin-like Growth Factor): Promotes cell proliferation and overall tissue growth. Uses in Skincare and Medicine Serums and Anti-Aging: Lab-made or bio-fermented growth factors are used in topical products to target fine lines and improve texture with low irritation. Clinical Medicine: Applied in wound care, tissue engineering, and regenerative therapies.
