Product Description


Pterostilbene is a natural dietary compound. It was first found in red sandalwood root, so it was named "red sandalwood root". Later, it was also found in grapes, blueberries and other fruits. Compared with other stilbene compounds, such as resveratrol, red sandalwood stilbene has higher bioavailability. In animal studies, red sandalwood stilbene has been proved to have a bioavailability of up to 80%. Many clinical studies have shown that red sandalwood stilbene has antioxidant activity both in vivo and in vitro, and it can help with anti inflammation, anti-oxidation and anti-aging.

As a methylated stilbene molecule, it has a structure similar to the antioxidant resveratrol. Red sandalwood stilbene and resveratrol have many similar benefits, including resistance to oxidative stress, but red sandalwood stilbene has been proved to have superior bioavailability.

Product Function


1. Inhibits melanin. Red sandalwood stilbene has a very strong ability to inhibit melanin, even surpassing the light licorice root, which is called "whitening gold", and has a highly effective freckle removal effect.

2. It inhibits tyrosinase. Tyrosinase is the key enzyme for melanin synthesis. The half inhibitory concentration IC50 value of photoglycyrrhizin, known as "whitening gold", on tyrosinase is the lowest among all products. The red sandalwood stilbene is slightly lower than photoglycyrrhizin, but it is obviously superior to other whitening materials such as VC and arbutin.

3. Antioxidant. Free radicals are everywhere, both from the body and from the outside. 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 the skin cells, make the skin lose elasticity, rough and aging wrinkles, and aggravate the oxidative damage of the skin. Red sandalwood root has excellent antioxidant effect. Its oxygen free radical absorption ORAC value is up to 12508 μ Mol trolox equivalents/g, 3 times as much as Vc and glycyrrhizin; The ability of inhibiting DPPH free radicals is slightly lower than Vc.

4. UV resistant. Ultraviolet radiation was used to irradiate the treated and untreated mouse fibroblasts respectively, and the anti ultraviolet ability of red sandalwood stilbene was known by detecting the activity of fibroblasts.

5. Anti inflammatory effect. There are some destructive enzymes in the human body, such as elastase and collagenase, which will damage the skin structure, making the skin loose and aging. Red sandalwood stilbene has dual inhibition ability, and inhibits two kinds of destructive enzymes at the same time.

6. Anti saccharification. The saccharification reaction in the skin field refers to the accumulation of too much reducing sugar due to the slow metabolism of the skin. Carbohydrates are easy to react with collagen and elastin in the skin to form irreversible brown end glycosylation products (AGEs), which can denature and crosslink collagen or elastin, and make the skin wrinkled, rough, dark and yellow. Red sandalwood root can reduce the content of cross-linked protein, inhibit the saccharification reaction, reduce the generation of AGEs, and achieve the effect of removing jaundice and anti-aging.
