L-Glutathione Powder (99% Pure Active)

L-Glutathione Powder (99% Pure Active) is a tripeptide synthesized from three specific amino acids: Cysteine, Glutamic Acid, and Glycine. In clinical skincare chemistry, it is recognized as a high-performance antioxidant that supports the skin’s natural defense against oxidative markers caused by environmental exposure (see dermatology review).

Formulation Benefits

• Luminosity Signal: Promotes a refined, even-looking complexion by supporting the skin’s natural renewal process.
• Barrier Support: Contributes to a resilient skin surface and a healthy-looking tone.
• Tone Uniformity: Traditionally used in professional brightening serums to address the appearance of surface discoloration.

Note: Because L-Glutathione is highly sensitise to light and air, it is not recommended for open-jar packaging. Always use airless pumps or amber glass to maintain its molecular soul.

Our L-Glutathione is a raw cosmetic ingredient intended for use in topical personal care formulations only. To ensure stability and efficacy, we recommend this active for advanced formulators or those working alongside a cosmetic chemist.
