Product Informations
Grape seed proanthocyanidin (grape seed extract) is a natural antioxidant with a variety of biological activities. Its super ability to scavenge free radicals and inhibit lipid peroxidation is a prerequisite for its wide application in cosmetics. Grape seed proanthocyanidins have various effects in cosmetics, which can play the roles of anti-aging and anti-aging, whitening and sun protection, anti-wrinkle and moisturizing, and have become the focus of research and development in the field of related cosmetics.
Application of grape seed proanthocyanidins in cosmetics
1. Anti-wrinkle effect
The production of wrinkles is a complex phenomenon. From a physiological point of view, it mainly involves two types of reactions: cross-linking and degradation of skin proteins and connective tissue. The anti-wrinkle effect of proanthocyanidins is based on its ability to maintain collagen synthesis; inhibit elastase; assist the body to protect collagen and improve skin elasticity; improve healthy circulation of the skin. Thereby avoiding or reducing wrinkles.
2. Sunscreen and whitening effect
Most of the reported sunscreen and whitening cosmetics are oily products, which are locally irritating to the skin and even have carcinogenic effects. Therefore, it is of great significance to screen water-soluble sunscreen and whitening agents with ultraviolet absorption from natural products. Oligomeric proanthocyanidins are pure natural, water-soluble, and have strong UV absorption at 280nm. It can inhibit the activity of tyrosinase; it can reduce the o-phthaloquinone structure of melanin to a phenolic structure, so that the pigment fades; it can inhibit the Maillard reaction caused by protein amino groups and nucleic acid amino groups, and inhibit lipofuscin, The formation of age spots. Can play a synergistic effect with vitamin Vc or VE. These characteristics of oligomeric proanthocyanidins make it occupy an important position in foreign sunscreen and whitening cosmetics.
3. Astringent and moisturizing effect
The astringent effect of proanthocyanidins makes cosmetics containing proanthocyanidins have good adhesion to the skin under waterproof conditions, and can shrink large pores. Sweat glands swell, tightening loose skin, tightening it, and reducing wrinkles, giving the skin a delicate appearance. The moisturizing effect of proanthocyanidins is based on the polyhydroxy structure of proanthocyanidins, which is easy to absorb moisture in the air; proanthocyanidins can compound with polysaccharides (hyaluronic acid), proteins, lipids (phospholipids), polypeptides and other properties.
4. Anti-radiation
The theory of free radicals is the theoretical basis of radiation damage. After the body is exposed to radiation, endogenous free radicals are generated, causing damage such as lipid peroxidation. The polyhydroxy structure of grape seed proanthocyanidins makes it have a strong effect of scavenging free radicals and inhibiting oxidative damage.
