Glutathione
What is Glutathione?
Glutathione is a tripeptide molecule made from the amino acids glutamic acid, cysteine, and glycine, naturally present in living cells as a key antioxidant. In skincare, it belongs to the category of functional actives found in serums, creams, and treatments. It works by donating electrons to neutralize reactive oxygen species, helping maintain cellular balance. As a reducing agent, it facilitates chemical reactions like those in hair waving products. It also serves in fragrance systems to balance scents and obscure off-notes. Sourced through synthesis or yeast fermentation, it integrates into formulas to bolster antioxidant defenses and influence pigmentation pathways for brighter-looking skin.
