A-LIPOIC ACID

Lipoic acid has a strong antioxidant capacity, and its ability to resist free radicals is 400 times better than VC and VE. It can remove reactive oxygen species that cause skin aging, and its molecules are smaller than VE.Besides, it is also water-soluble and fat-soluble, so it is quite easy for the skin to absorb.

Lipoic acid not only has a strong resistance to long-term oxidative damage, but also can effectively repair the more serious oxidative damage that VC and VE can not repair. Studies have shown that lipoic acid can be converted into dihydrolipoic acid in the body, and both of them have strong antioxidant properties and act synergistically in the body. At the same time, the molecular weight of lipoic acid is between ascorbic acid and tocopherol, and Chemicalbook is amphiphilic with water and lipid, which can play a comprehensive antioxidant effect in the body, known as the "universal antioxidant".

The antioxidant effect of lipoic acid is mainly reflected in three aspects:

1. Direct scavenging of free radicals, lipoic acid can directly play a role in scavenging hydroxyl free radicals, singlet oxygen and other free radicals after entering the cells;

2, inhibition of metal-induced oxidation, lipoic acid has the effect of chelating metal ions, thereby reducing the peroxidation of lipids and other macromolecules caused by metal ions;

3. Promote the recovery of other antioxidant components. Lipoic acid can restore the ability of endogenous antioxidants such as vitamin E and glutathione in the body, so as to improve the overall antioxidant capacity of the body.
