Resveratrol Extract Powder

The resveratrol extracted from knotweed and the resveratrol extracted from grapes differ in the source. Knotweed is a perennial herb whose roots are used to extract resveratrol. Grapes, on the other hand, are vines whose seeds are used to extract resveratrol.

In addition to the different sources, the two extracts also have some differences in chemical composition and pharmacological effects. The resveratrol extracted from Polygonum cuspidatum mainly contains resveratrol and its isomer dogwood alcohol, which has anti-oxidation, anti-inflammatory and antibacterial effects. The resveratrol extracted from grapes mainly contains resveratrol and its isomers and its derivatives, which show stronger activities in anti-oxidation, anti-inflammation, and anti-tumor.

Resveratrol extracted from grapes has the following advantages:

Stronger antioxidant effect: Resveratrol extracted from grapes contains more active ingredients, which can more effectively neutralize free radicals and inhibit oxidation reactions, thereby protecting cells from oxidative damage.

The anti-inflammatory effect is more significant: Resveratrol extracted from grapes has a stronger anti-inflammatory effect by inhibiting inflammatory factors and regulating inflammatory signaling pathways. This has a positive effect on reducing symptoms of inflammation-related diseases and inflammatory pain.

Higher anti-tumor activity: Resveratrol extracted from grapes has a stronger anti-tumor effect, can inhibit the growth and division of tumor cells, induce tumor cell apoptosis, and thus effectively inhibit the development and spread of tumors.

In general, although the resveratrol extracted from Polygonum cuspidatum also has certain pharmacological effects, the resveratrol extracted from grapes has stronger antioxidant, anti-inflammatory, and anti-tumor activities, so it is more important in drug development and clinical practice. There may be more potential in treatment.

• Antioxidant: As a powerful antioxidant, resveratrol can neutralize free radicals and prevent oxidative stress from damaging the skin. Free radicals are one of the main contributors to skin aging, leading to the degradation of collagen and elastin, causing fine lines, wrinkles, and hyperpigmentation. The antioxidant properties of resveratrol can delay these skin aging processes, leaving skin looking younger and healthier.

In a study published in the journal Food Chemistry, scientists looked at the effects of resveratrol on oxidative stress. Studies have found that resveratrol can significantly reduce oxidation indicators in skin tissue, such as peroxidase activity and lipid peroxide levels, thereby protecting the skin from oxidative damage.

• Anti-inflammatory: Resveratrol has anti-inflammatory properties, which can reduce skin inflammation and relieve symptoms such as redness, itching, and pain. Inflammation in the skin is often caused by external stimuli, bacterial infections, or allergies, and resveratrol can reduce or block the inflammatory process by inhibiting the production of inflammatory factors and the regulation of inflammatory signaling pathways.

• Moisturizing and nourishing: Resveratrol can strengthen the function of the skin barrier, reduce water loss, and help maintain the water-oil balance of the skin. It also hydrates and moisturizes the skin, making it soft and smooth. In the study published in the International Journal of Cosmetic Science, researchers used instruments to measure the effect of resveratrol on skin moisture levels and skin barrier function. The results show that the application of resveratrol can significantly increase the moisture content of the skin and improve the skin barrier function, thereby maintaining the water-oil balance of the skin and making the skin moist and soft.

• Antibacterial and antiviral: Resveratrol has certain antibacterial and antiviral capabilities, which can help remove harmful bacteria and viruses on the surface of the skin and reduce the occurrence of infection and inflammation.
