Glutathione ●
TL;DR. This ingredient is used mainly as an antioxidant and skin-tone support active, helping protect formulas and skin from oxidative stress. It is also used in brightening products because it can influence visible discoloration pathways.
What does Glutathione do in a cosmetic formula?
This ingredient is used mainly as an antioxidant and skin-tone support active, helping protect formulas and skin from oxidative stress. It is also used in brightening products because it can influence visible discoloration pathways.
Is Glutathione clean?
It is generally well-tolerated and does not carry major clean-standard restricted-list concerns. Sensitivity is uncommon, though stability and sourcing transparency matter more than irritation for this material.
Is Glutathione sustainable?
This material is commonly produced by fermentation or biotechnology, which can align well with lower-impact sourcing when managed responsibly. It is water-soluble and expected to be readily biodegradable rather than environmentally persistent.
Is Glutathione COSMOS-approved?
It can be compatible with COSMOS-natural or COSMOS-organic standards when produced from permitted natural feedstocks and compliant fermentation or processing methods. From a Green Chemistry perspective, it aligns best when made through biotechnology, with biodegradable output and minimal solvent burden.
How does Glutathione work chemically?
This molecule is a water-soluble thiol-containing tripeptide built from glutamate, cysteine, and glycine, with antioxidant behavior tied to reversible thiol-disulfide redox chemistry. In topical formulas it is typically used at low levels, often around 0.1–2%, and is best protected from heat, oxygen, metal ions, and high pH because oxidation can reduce potency.
