The fibroblast growth factor (FGF) is renowned for its ability to stimulate the growth and mitogenesis of fibroblastic cells, supporting skin regeneration. Additionally, it is a key ingredient in rejuvenation treatments, as it promotes the production of collagen and elastin, which are essential for maintaining skin firmness and elasticity. Produced through advanced bioengineering via glucose fermentation, its molecular structure and biological activity are identical to the FGF naturally generated by the human body, making it a valuable component for maintaining healthy and revitalized skin.
