Bio-GHK is a synthetic peptide that cleverly combines the properties of biotin and tripeptide, showing significant effects in promoting hair growth, reducing hair loss, and making eyelashes thicker and stronger. This ingredient effectively improves the structure of hair follicles by promoting the synthesis of collagen IV and laminin 5, helping hair to be firmly fixed in the dermal follicles, thereby preventing the occurrence of hair loss. In addition, Bio-GHK can also activate tissue repair genes, accelerate the production of proteins in the skin and hair, promote cell proliferation and differentiation, and further stimulate hair growth.
