3.Effects
●Inhibit melanin
Pterostilbene has a strong ability to inhibit melanin, even surpassing glabridin, known as "whitening gold", and has a highly effective freckle removal effect.
●Inhibit tyrosinase
Tyrosinase is a key enzyme in the synthesis of melanin. Glabridin, known as "whitening gold", has the lowest half inhibitory concentration IC50 value of tyrosinase among all products. Pterostilbene is slightly lower than glabridin, but obviously Superior to other whitening ingredients VC, arbutin, etc.
●Anti-oxidation
Free radicals are everywhere, both internally and externally. When the free radicals in the human body exceed a certain amount, they will cause various damages to our body. The free radicals in the air will directly attack the skin, snatch electrons from skin cells, make the skin lose its elasticity, cause rough aging and wrinkles, and aggravate the oxidative damage of the skin. Pterostilbene has excellent antioxidant properties. Its oxygen free radical absorption ORAC value is as high as 12508μmol trolox equivalents/g, which is three times that of VC and glabridin.
●UV protection
The pterostilbene-treated and untreated mouse fibroblasts were respectively irradiated with ultraviolet rays, and the ability of pterostilbene to resist ultraviolet rays was known by detecting the activity of fibroblasts.
●Anti-inflammatory effect
Pterostilbene may activate reduced coenzyme Ⅱ oxidase through protein kinase C, thereby stimulating neutrophils not to produce superoxide superoxide anion and myeloperoxidase, and its effect is significantly reduced at 100 μmol/L, so the effect of pterostilbene The effect may be dose-dependent. Pterostilbene has the ability to inhibit the activation of nuclear factor NF-κB, thereby inhibiting the activation of pro-inflammatory cytokines and nitric oxide synthase genes, resulting in decreased secretion of tumor necrosis factor-α, interleukin-1β, interleukin-6 and nitric oxide, thereby alleviating Inflammatory stimulus response. There are some destructive enzymes in the human body, such as elastase and collagenase, which will destroy the skin structure, make the skin loose and aging. Pterostilbene possesses dual inhibitory abilities, inhibiting two destructive enzymes at the same time.
●Anti-glycation
The glycation reaction in the skin area refers to the excessive accumulation of reducing sugars in the skin due to the slow metabolism, and the sugars are easy to react with the collagen and elastin in the skin to form irreversible brown terminal glycation products (AGEs), making Collagen or elastin is denatured and cross-linked, and the skin becomes wrinkled, rough and dark yellow. Pterostilbene can reduce the content of cross-linked proteins, inhibit the glycation reaction, reduce the production of AGEs, and achieve the effect of dispelling jaundice and anti-aging.
