The Claim
A popular belief is that glutathione can lighten skin tone by reducing melanin production, leading to fairer skin.
Origin
This myth has been propagated heavily through beauty industry marketing and anecdotal reports, particularly in regions where lighter skin is culturally valued.
What Science Says
Several small studies and some randomized controlled trials have suggested that glutathione may have skin-lightening effects due to its role in inhibiting melanin synthesis. However, comprehensive meta-analyses are lacking, and the long-term safety and efficacy of such use remain uncertain. The cosmetic use of glutathione for skin lightening is not universally endorsed by dermatologists.
Verdict
Mostly True
