Pine bark extract is a kind of substance extracted from pine bark. The bark of the pine tree is collected, flattened and extracted. It contains a large number of compounds called OPCs(procyanidin oligomers). In a large number of studies, OPCs have been proved to be effective antioxidants, non-toxic, non-mutative, non-carcinogenic and no side effects. Pine bark has been proved to be a new source of OPCs. OPCs extracted from pine bark have no difference in quality and function, but some slight differences in appearance.
The antioxidant power of pine bark extract comes from procyanidins (procyanidin oligomers)(OPCs), which have 20 times the antioxidant power of vitamin C and 50 times that of vitamin E. As a well-known antioxidant, OPCs can effectively suppress the effects of free radicals, which play an important role in degenerative diseases, cardiovascular diseases, blurred vision, sunburn and premature aging.
Studies have confirmed that OPCs can help strengthen capillaries, arteries and veins, giving them many important clinical applications. OPCs are used to stabilize blood vessel walls, suppress inflammation, and primarily support tissues containing collagen and elastin.
Due to their antioxidant power, OPCs are thought to protect the skin from excess UV radiation and free radicals. There is considerable evidence that OPCs protect and strengthen collagen and elastin in the skin, thereby preventing wrinkles and maintaining skin elasticity. Adding OPCs to creams is a popular way to slow the aging of skin, theoretically restoring youthful glow by repairing collagen and elastin.
