Glutathione (GSH) is a low molecular weight thiol tripeptide composed of three amino acids: glutamic acid, cysteine and glycine. It has a strong antioxidant effect. Glutathione is usually used to make oral health care products, injections and other products, and is widely used in medical, beauty, health and other fields.
When there is oxidative stress in the human body, glutathione can exert a protective effect in two ways:
a. Directly remove free radicals: The skin is stimulated by external environments such as ultraviolet rays and pollutants, which will produce harmful substances such as free radicals, leading to oxidative damage. Glutathione can react with harmful substances such as free radicals and convert them into free radicals. harmful substances and protect cells from oxidative damage.
b. Indirectly participate in the antioxidant process: Glutathione can work with other antioxidants such as vitamin C, vitamin E, etc. to enhance their antioxidant capacity and protect cells from oxidative damage.
Glutathione’s effects on skin:
1. Inhibit the production of melanin: Glutathione can inhibit tyrosinase activity through thiol chelating copper sites and its antioxidant effect, reducing pigmentation, thus playing a whitening effect.
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 inflammatory response, 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 and waste cells, and maintain the vitality and elasticity of the skin.
How to supplement glutathione:
1. Glutathione for injection
Glutathione is non-toxic and generally well tolerated, but injectable glutathione requires the guidance of a professional doctor, preferably in a regular hospital.
2. Take orally
Oral administration is the simplest and most common way to do it, especially if it is to be taken long-term. Research shows that the most effective route of oral glutathione is absorption from the oral mucosa.
3. Local application to skin
Glutathione is a small molecule peptide, and smear-on glutathione can also achieve partial whitening effects.
It should be noted that glutathione needs to be stored in a dry, light-proof, and low-temperature environment. In addition, the amount and concentration of glutathione should also be matched with other formula ingredients to avoid unnecessary chemical reactions or affecting product quality.
