What is White Willow Bark Extract?

White willow bark extract is extracted from the bark, branches and stems of the willow family, Willow family, and then spray dried. The main active ingredient is salicin, which in its state is a fine brown or off-white powder with aspirin-like properties, and is an effective anti-inflammatory ingredient traditionally used to heal wounds and relieve muscle pain.
Studies have found that salicin is an inhibitor of oxidase (NADHoxidase), which has anti-wrinkle, increases skin radiance and elasticity, reduces pigmentation, increases skin moisture and other effects, and has anti-aging, exfoliating, oil control and acne skin care effects in cosmetics.

Applications of White Willow Bark Extract:

The main active ingredient, salicin, not only affects the regulation of genes in the skin, but also regulates gene clusters associated with the biological process of skin aging, which are called functional "youthful gene clusters". In addition, salicin plays an important role in the production and maintenance of collagen, one of the key proteins in the skin, thus increasing skin elasticity and achieving anti-wrinkle effects.

White willow bark extract has a significant life-extending effect on yeast, up to 5 times longer, and is a promising anti-aging ingredient, more so than rapamycin.

White willow bark extract not only has excellent anti-aging and anti-wrinkle properties, but also has highly effective anti-inflammatory activity. Salicin has some anti-inflammatory properties due to its aspirin-like properties and can be used to relieve facial acne, herpetic inflammation and sunburn. It contains salicylic acid, a BHA, which is a natural exfoliator used in several acne treatments because it helps the skin shed dead cells while clearing pores. It also contains phenolic acids, including salicin, salicortin and flavonoids, tannins and minerals that help rejuvenate the skin.
