The IGF-I growth factor is recognized for its ability to promote muscle growth and the development of lean tissue in muscles and ligaments. Additionally, it supports fat burning by targeting adipose cells, contributing to increased lean body mass, reduced fat, and improved physical endurance. Produced through biofermentation from bacteria, its molecular structure and biological activity are identical to the IGF-I naturally generated by the human body. This factor also stimulates protein synthesis, accelerating tissue repair and aiding skin recovery after aesthetic procedures. At the dermal level, IGF-I helps restore the skin’s phospholipid profile and works synergistically with EGF in skin regeneration. Furthermore, it increases the synthesis of hyaluronic acid and chondroitin sulfate proteoglycans by fibroblasts, making it a key component for maintaining healthy and regenerated skin.
