The BIOEFFECT EGF eye serum in the treatment is a powerful anti-ageing formula, containing higher concentration of EGF than in the regular eye serum. It is specifically developed to target the sensitive skin of the eye area. EGF naturally occurs in human skin where it turns on biological processes involved in the maintenance of healthy looking skin. The powerful dose of EGF works as a biochemical messenger to the skin around the eyes, signaling broblasts deeper in the tissue which are responsible for collagen production.
