    Glutathione (GSH), also named Reduced Glutathione, is a tripeptide composed of glutamate, cysteine, and glycine. It can be found in almost every cell of human body. Nowadays, the industrial production of Glutathione is mainly obtained by enzymatic synthesis. In the method, Glutathione has a high purity and good water-solubility. As an active tripeptide with important physiological functions, Glutathione is the most important non-protein sulfhydryl compound in organisms. It has biological activities such as detoxification, anti-oxidation, free radical scavenging, skin-whitening and spot-fading. Therefore, it is widely used in cosmetics, medicine, health care products and other industries. It can be soluble in water greatly and easy to be added into all kinds of skin-whitening cosmetics.

    Glutathione Key Functions 

    Skin Whitening & Brightening:Inhibits melanin synthesis by reducing tyrosinase activity, fading dark spots and evening skin tone.Neutralizes free radicals that contribute to pigmentation disorders like melasma.

    Antioxidant Defense:Scavenges reactive oxygen species (ROS) from UV exposure and pollution, preventing collagen degradation and premature aging.Protects skin lipids and DNA from oxidative damage.

    Anti-Inflammatory Effects:Reduces redness and irritation caused by acne, eczema, or post-procedure inflammation.Calms skin sensitivity and itching.

    Hydration & Skin Barrier Support:Improves skin moisture retention by enhancing the stratum corneum’s lipid barrier.Promotes a smoother, plumper complexion.

    Hair Health:Combats oxidative stress in hair follicles, reducing breakage and graying.Supports scalp health and keratin production.

    Glutathione   Mechanism of Action

    Direct Radical Scavenging:Glutathione’s thiol group directly neutralizes free radicals, breaking oxidative chain reactions.

    Indirect Antioxidant Support:Regenerates other antioxidants like vitamins C and E, amplifying their effects.

    Melanin Regulation:Inhibits tyrosinase, the enzyme critical for melanin production, without cytotoxicity.

    Cellular Detoxification:Binds to heavy metals and toxins, aiding their elimination from the skin.
