Topical Whitening Efficacy of Oxidized Glutathione
Oxidized glutathione is a more stable form of glutathione that is better suited for topical skin care applications, making it an ideal candidate for localized skin whitening.
A trial enrolled 30 healthy women aged 30-50 and evaluated the whitening and skin-quality-improving effects of oxidized glutathione over a continuous 10-week period.
The results showed that oxidized glutathione produced a marked whitening effect.
Starting from the first week of trial, melanin index in facial areas treated with oxidized glutathione declined steadily.
Beyond lightening, the ingredient also delivered comprehensive skin-quality benefits.
During second half of trial, stratum-corneum water content in oxidized-glutathione group rose significantly, while formation of periocular wrinkles was suppressed and skin smoothness markedly improved—demonstrating a dual action of "whitening plus skin nourishment".
