Glutathione, a tripeptide molecule comprised of glutamine, cysteine, and glycine, plays a pivotal role in the body as an antioxidant, detoxifying agent, and immune system enhancer. Recently, it has garnered attention for its potential in skin lightening.
Here's how L-glutathione, with its remarkable 99% purity, aids in reducing UV damage and brightening the complexion:
Inhibition of melanin production:
Glutathione is thought to inhibit the enzyme tyrosinase, which is involved in the production of melanin, the pigment responsible for skin color. By reducing the activity of tyrosinase, glutathione may decrease the production of melanin, leading to lighter skin.
Antioxidant properties:
Glutathione is a powerful antioxidant that helps neutralize free radicals in the body. Free radicals can damage skin cells and contribute to hyperpigmentation. By scavenging free radicals, glutathione may help prevent or reduce skin darkening.
Regulation of melanogenesis genes:
Glutathione may also regulate the expression of genes involved in melanin production, leading to decreased pigment formation in the skin.
Research backs these claims. In a study by Lee et al. (2012), 30 Korean women supplemented with oral glutathione (500 mg/day) for 12 weeks witnessed a significant decrease in melanin index and improvement in skin lightness compared to a placebo group.
