Product Informations

Procyanidins are natural antioxidants with a variety of biological activities.Their strong ability to scavenge free radicals and inhibit lipid peroxidation is the prerequisite for their wide application in cosmetics.The application of Procyanidins in cosmetics has a variety of effects,such as anti-aging,anti-aging,whitening,sun protection,anti wrinkle and moisturizing.It has become the research and development focus in the field of cosmetics.
Application of Procyanidins in cosmetics
1.Anti wrinkle effect
The generation of wrinkles is a complex phenomenon.From a physiological point of view,it mainly involves the cross-linking and degradation of skin proteins and connective tissue.The anti wrinkle effect of procyanidins is based on its ability to maintain collagen synthesis;Inhibition of elastase;Assist the body to protect collagen and improve skin elasticity;Improve healthy circulation of skin.So as to avoid or reduce the generation of wrinkles.
2.Sunscreen whitening effect
Most of the reported sunscreen and whitening cosmetics are oily products,which are locally irritating to the skin and even carcinogenic.Therefore,it is of great significance to screen water-soluble sunscreen and whitening agents with ultraviolet absorption from natural products.Oligomeric Procyanidins are pure natural,water-soluble,and have strong UV absorption at 280nm.It can inhibit the activity of tyrosinase;The o-benzoquinone structure of melanin can be reduced to a phenol type structure to make the pigment fade;It can inhibit the Maillard reaction caused by protein amino group and nucleic acid amino group,and inhibit the formation of lipofuscin and senile plaque.It can have synergistic effect with vitamin VC or VE.These characteristics of oligomeric procyanidins make them play an important role in sunscreen and whitening cosmetics abroad.
3.Astringent and moisturizing effect
The astringent effect of Procyanidins makes cosmetics containing Procyanidins have good adhesion to the skin under waterproof conditions,and can shrink large pores.Sweat glands swell,making loose skin astringent,tight and reducing wrinkles,so that the skin shows a delicate appearance.The moisturizing effect of procyanidins is based on the fact that procyanidins have a polyhydroxy structure and are easy to absorb moisture in the air;Procyanidins can combine with polysaccharides(hyaluronic acid),proteins,lipids(phospholipids),peptides,etc.
4.Radiation resistance
The theory of free radicals is the theoretical basis of radiation injury.After radiation,the body produces endogenous free radicals,causing lipid peroxidation and other damage.The multi hydroxyl structure of Grape Seed Extract Procyanidins makes it have a strong effect of scavenging free radicals and inhibiting oxidative damage.
