As the result of 1986 Nobel Prize, cell growth factor has been used in medical field before, and it has only been used in skin care products in recent years. My current unit, Kangbao Research Institute under Kangbao Huitai, is engaged in research and development in this field. There are many cell growth factors, such as vascular endothelial growth factor (VEGF), epidermal growth factor (EGF), fibroblast growth factor (BFGF) and recombinant human keratinocyte growth factor -2 (KGF-2), which can activate aging cells, promote the nutritional metabolism of epidermal cells, and prevent and repair various diseases. Improve local vascular permeability, enrich blood supply, activate the function of subcutaneous collagen cells, accelerate the growth of skin collagen cells, increase collagen secretion, make subcutaneous dermis full, arrange muscle fibers neatly and tightly, reduce and eliminate wrinkles, and reduce the secretion and deposition of melanin in skin cells, thus playing a role in lasting whitening, anti-wrinkle and delaying skin aging.
