Author: China Glutathione suppliers & manufacturers Release time: 2023-07-28 Column: Product News


Glutathione (GSH) is a low-molecular-weight thiol tripeptide, which is composed of three amino acids: glutamic acid, cysteine and glycine, and has a strong antioxidant effect. It can be dissolved in water, and can also be purified by chemical methods to obtain glutathione in the form of crystal powder. Crystal powdered glutathione is usually used to make oral health care products, injections and other products, and has a wide range of applications in medical, beauty, health and other fields.


When there is oxidative stress in the body, glutathione can play a protective role in two ways:

1. Direct removal of free radicals: The skin is stimulated by external environments such as ultraviolet rays and pollutants, which will produce free radicals and other harmful substances, resulting in oxidative damage. Glutathione can react with free radicals and other harmful substances and convert them into free radicals. Harmful substances, and protect cells from oxidative damage.

2. Indirect participation in the antioxidant process: Glutathione can work together with other antioxidants such as vitamin C and vitamin E to enhance their antioxidant capacity and protect cells from oxidative damage.

Effects of external glutathione on the skin

1. Inhibit the formation of melanin: Glutathione can inhibit the activity of tyrosinase through sulfhydryl chelating copper sites and its antioxidant effect, reduce pigmentation, and thus play a whitening role.

2. Promote the synthesis of collagen: Glutathione can promote the synthesis of collagen in the skin, increase skin elasticity and firmness, and play a certain anti-aging effect.

3. Repair damaged skin: Glutathione can promote the repair of damaged skin, reduce oxidative damage and inflammation, and improve skin quality.

4. Improve skin immunity: Glutathione can promote the activation of the immune system, enhance skin resistance, and reduce the occurrence of skin infection and inflammation.

5. Promote cell metabolism: Glutathione can promote the metabolism of skin cells, accelerate the renewal of old waste cells, and maintain the vitality and elasticity of the skin.

Glutathione is a small molecular peptide, which is easily absorbed by the skin and has obvious effects when applied externally, but the dosage should not be too high, otherwise unnecessary side effects such as allergies and irritation may occur. The specific dosage and concentration can be determined according to the formula of the product, the object of use and the purpose of use.

It should be noted that glutathione has poor stability and is easily destroyed by light, oxygen, acid and other factors. It needs to be stored in a dry, dark and low temperature environment. Generally speaking, when making skin care products, appropriate auxiliary materials such as antioxidants, humectants, and plasticizers should be selected to maintain the stability and activity of the finished product, but it also reduces the purity of the product. In addition, the amount and concentration of glutathione should also be matched with other formulation ingredients to avoid unnecessary chemical reactions or affect the quality of the product.
