Glutathione for Skin Whitening and Other Benefits

Regarding the use of Glutathione for skin whitening and its effective concentration, based on the information available:

Glutathione is primarily a highly effective antioxidant. Its main use in formulations is often to enhance the stability of ingredients like L-Ascorbic Acid (Vitamin C).

While some product descriptions mention that Glutathione can act as a skin whitening agent through its antioxidant process, the primary benefit and accepted use is as an antioxidant. One product description suggests a usage rate of 2% for formulations targeting whitening, within a general range of 1-3% for powder forms (such as Glutathione (L-Glutathione) (Extrasol) and Glutathione (L-Glutathione Reduced)). For the liquid form (L-Glutathione Liquid (Deodorized, Colorless)), the suggested usage rate is 5-10%.

However, it's important to note that achieving significant, visible skin whitening effects from topical Glutathione is often debated, and its role as a powerful antioxidant is more widely accepted and utilized in cosmetic science.

Other Benefits:

Beyond its antioxidant properties, related compounds like N-Acetyl Cysteine, which is a precursor that helps the body synthesize Glutathione, have been associated with other benefits in research, including:

• Strengthening hair roots and reducing hair loss
• Aiding in wound healing
• Reducing acne breakouts
• Improving symptoms of certain skin conditions like Lamellar Ichthyosis and Atopic Dermatitis (at higher concentrations).

In summary, while a 2% concentration of powder forms of Glutathione is suggested in some descriptions for potential whitening effects via its antioxidant action, its core function and widely recognized benefit in formulations is as a potent antioxidant, particularly useful for stabilizing other sensitive ingredients like Vitamin C.
