The vascular endothelial growth factor (VEGF) is a key protein that stimulates the formation of new blood vessels through vasculogenesis and angiogenesis. Additionally, in hair growth stimulation, VEGF promotes the creation of new blood vessels to improve blood supply to the hair follicle, thus increasing nutrient delivery. Produced through biofermentation from bacteria, VEGF becomes a valuable ingredient for promoting cellular regeneration and improving the health of both the skin and scalp.
