Anti aging plant extract

Last revised: 2013-03-12 02:06 classification: efficacy and action 0 person review With the continuous growth of age, our skin will begin to show a state of aging: including the content of collagen, mucopolysaccharide and elastin in our skin decreased to varying degrees; the blood vessels supplying nutrition to our skin in circulation began to shrink, the wall elasticity of blood vessels began to decrease, and the skin epidermis began to swell and thin gradually; the subcutaneous fat began to reduce and wrinkle and yellow Brown spots and age spots appear The main reason for these phenomena is the increasing number of free radicals Therefore, eliminating excessive free radicals in human body is an important way to solve skin aging Procyanidins, or OPC for short, is a kind of bioflavonoids with special molecular structure, which is the most effective natural antioxidant for scavenging free radicals in human body Generally, it is reddish brown powder, with slight gas and astringent taste, soluble in water and most organic solvents The highest content of OPC in grape seed extract is 95% The experiment shows that OPC has 50 times the anti free radical oxidation ability of vitamin E and 20 times of vitamin C Studies at home and abroad have shown that procyanidins can resist free radicals, anti-aging, help vitamin C and E absorption, reduce UV damage, reduce melanin deposition, prevent collagen fiber and elastic fibers from breaking, keep skin's elasticity and tension, avoid skin drooping and wrinkles The anti wrinkle, whitening, moisturizing and anti radiation effects of proanthocyanidins have opened up a broad prospect in the field of cosmetics It is also known as plant tannin, which is a complex secondary metabolite of phenols in plants, and has a polyphenol structure Common polyphenols include tea polyphenols, grape polyphenols, Peel Polyphenols, etc It has the functions of anti-oxidation, eliminating free radicals, promoting cell self-healing and inhibiting melanin source It can also achieve whitening effect by absorbing ultraviolet light, effectively absorb the ultraviolet light in the whole area by compounding, and reduce the generation of melanin Skin blackening, freckles, brown spots and senile spots are closely related to the increased activity of tyrosinase and peroxidase in the body Tyrosinase plays a catalytic role in the metabolism of melanocytes in skin tissue, resulting in the increase of melanin secretion, peroxidase catalyzing the process of lipid peroxidation and decomposition, and accelerating skin aging Plant polyphenols have whitening effect by inhibiting tyrosinase and peroxidase It is a new type of natural antioxidant Under normal temperature and low concentration, tea polyphenol has strong antioxidant ability It can block ultraviolet rays and remove the free radicals induced by ultraviolet rays, so as to protect the normal function of melanin cells At the same time, it can also inhibit the activity of tyrosinase and catalase in cells, so as to reduce the secretion of melanin and lipid peroxidation, and achieve the effect of freckle removal and beauty Polyphenol active substances extracted from grapes are widely found in the skin, seeds and pulp of grapes The content of polyphenols in grape seeds is about 5% - 8% Grape polyphenols are mainly composed of oligoprocyanidins by condensation of catechins and epicatechins Grape polyphenol has a strong antioxidant, can resist the damage of free radicals, effectively delay aging and promote metabolism An important class of bioactive substances in apple, which exist naturally, can be divided into phenolic acids and their hydroxy esters, sugar derivatives and flavonoids It can remove too many harmful free radicals in the body, inhibit the automatic oxidation of unsaturated fatty acids in the aqueous system, prevent the light damage of carotene, prevent the damage of water-soluble vitamins, and eliminate the activity of superoxide free radical ions In addition, the maturity of apple is different, and the content of main components is also different The polyphenols in mature apple are mainly chlorogenic acid, catechin and proanthocyanidins, while those in immature apple contain more dihydroxychalcone and flavonols.
