5-HTP? As we age, the body's ability to renew cells slows, the result of which is a decline in the elasticity and suppleness of your skin. The 5-HTP content in Griffonia Seeds (a real 'neuro-cosmetic') and their naturally occurring amino acids promote positive tightening and firming of the skin and fine lines. Caffeine & natural Biosaccharide Gum help to provide long-term anti-aging benefits through promoting collagen synthesis.
