Glutathione
Glutathione is a cellular tripeptide (glutamate, cysteine, glycine) used in skincare as an antioxidant. Topically it's included for tone-evening and radiance support, but stability and skin-penetration challenges mean visible results are inconsistent.

Our take
Is Glutathione a Good Ingredient?
It's Fair because, while it's biologically relevant, topical instability and limited penetration hold back consistent, noticeable outcomes. Irritation is generally low, though sensitive users may experience mild reactions, which is enough to keep it out of Good.
What it does
Skin Benefits
Provides antioxidant support that can reduce the look of dullness and uneven tone. Works best as part of an antioxidant blend rather than a standalone brightener.
Where you'll find it
Uses in Skincare & Cosmetics
Common in serums, essences, and sheet masks targeting radiance. Often paired with vitamins C/E or niacinamide in moisturizers.
Before you use it
Safety
Usually well tolerated; patch test if reactive. No known photosensitizing or comedogenic concerns at typical cosmetic levels.
