Sunscreen whitening effect

The sunscreen whitening cosmetics that have been reported so far are mostly oily products that have local irritation to the skin and even have carcinogenic effects. Therefore, it is of great significance to screen water-soluble sunscreen whitening agents having a UV absorbing effect from natural products. Oligomeric proanthocyanidins are pure, water-soluble, and have strong UV absorbance at 280 nm. It can inhibit the activity of tyrosinase; it can reduce the structure of o-phthalimidine in melanin into phenol structure and fade the pigment; it can inhibit the Maillard reaction due to protein amino group and amino acid amino group, and inhibit lipofuscin, The formation of age spots. It can work synergistically with vitamin Vc or VE. These characteristics of oligomeric procyanidins make it an important part in foreign sunscreen cosmetics.

"Proanthocyanidin" is not the strongest antioxidant. If VE is used as a comparison, the ability of lycopene (ψ-carotene) to scavenge free radicals is 100 times that of VE. However, the ability of OPC to scavenge free radicals is only 50 times that of VE. The ability of astaxanthin to scavenge free radicals is 1000 times that of VE!

However, this does not prevent OPC from becoming a natural free radical scavenger used in the medical and nutrition communities. The reason is that lycopene and astaxanthin, which have a stronger free radical scavenging activity than OPC, are all fat-soluble substances, that is to say, they must be dissolved in the organic phase in order to be absorbed. These substances, together with their low content in food, are not high. It can get very little from food. And if you do not absorb it, even if you have a stronger effect in the laboratory, you will not be able to exert a physiological effect.
