NEOCUTIS

Neocutis' proprietary skin care ingredient PSP (Processed Skin Cell Proteins) provides the most complete and balanced combination of human growth factors and cytokines currently available. 

Role of PSP® in anti-aging
Recent studies suggest that aged or photo-aged skin has the same needs as wounded skin, where growth factors and other cytokines interact synergistically to initiate and coordinate the wound healing response. Cytokines and growth factors are key elements in scar-less wound healing.
