Anti-aging is achieved through three methods:
- Anti oxidant: it’s Antioxidant is indirect through its metabolites. The metabolites Of HR can stimulate a known cell protectant called glutathione. It also stimulates antioxidant defense enzymes including glutathione peroxidase and glutathione reductase.
- Anti inflammatory: There is a factor called NF kappa beta that plays a key role in triggering inflammation. It has been shown that HR can stimulate collagen and elastin synthesis by inhibiting NF-kappa beta.
- Glycation: AGEs (advanced glycation end-products) are one of the factors in skin aging. One of their functions is to stimulate the breakdown of collagen. HR is thought to inhibit this reaction.
HR has a strong effect to inhibit tyrosinase and peroxidase which play a role in stimulating melanin production. It also stimulates the effect on glutathione and E-cadherin production which also play a role in inhibiting the production of melanin in the skin.
