Metallothionein: Polypeptide Metallothionein is a small molecule oligopeptide, containing a large amount of cysteine, which is a powerful anti-aging protein and harmful heavy metal scavenger. The active sulfhydryl group of cysteine makes metallothionein maintain high antioxidant capacity, and the ability of scavenging oxygen free radicals is 25 times that of glutathione.

Extraction and efficacy of metallothionein

MT has a very special molecular structure, which is easy to be absorbed by human skin and has good transdermal absorption performance. It is a non enzyme protein with stable activity and long-term invariability at room temperature. Compared with SOD, MT has smaller molecular weight, only 1 / 4 of SOD, which is more easily absorbed by skin; MT is more stable to heat than SOD, which is not suitable for decomposition; MT has a longer half-life than SOD, which is not suitable for denaturation.

Stability

Through the stability test, the current oligopeptide-4 was determined to be used in the production of cosmetics. It was added below 45 ℃ and stable at room temperature for 2 years.

Suggested Dosage 

Suggested Dosage: 1-4%

1. Antiaging Effect

It can effectively reduce the level of free radicals in the body, protect cells from peroxidation damage and prevent skin cells from aging.

2. Anti Radiation Effect

Studies in Japan have shown that MT cells do have the function of protecting cells from ultraviolet radiation.

3. Anti Inflammatory Effect

Clinical experiments show that MT can promote immune function and cell metabolism in inflammatory skin injury. So as to improve the anti-inflammatory ability.

4. Reduce the role of color spots

MT can effectively remove free radicals and hydroxyl radicals and block their peroxidation reaction, so it has the function of preventing and reducing pigmentation.

MT, as a biological activator, can play a variety of biochemical roles in cosmetics, such as anti-aging, wrinkle reduction, sun protection and anti-inflammatory, preventing and reducing color spots, and relieving heavy metal poisoning.
