Glutathione skin review reports possible benefits and unresolved safety questions
The abstract describes favorable skin findings for oral and topical glutathione, while calling for stronger trials and longer safety follow-up.

The 30-second takeaway
This review reports favorable findings for skin pigmentation, brightness and hydration with oral or topical glutathione. Injectable glutathione was described as having short-lived effects and potential safety concerns. The abstract combines molecular and clinical evidence without giving comparative effect sizes, so it cannot establish how much benefit a person might experience or which formulation performs best.
The abstract gives no participant characteristics, treatment schedules, comparison groups or numerical skin outcomes. It also provides no adverse-event rates, preventing a detailed assessment of the magnitude of benefit or the frequency of harms.
Mechanisms and visible skin changes
The review discusses antioxidant activity and pathways involved in skin aging and tissue repair. These mechanisms can help explain research questions, but they do not by themselves measure visible skin improvement or durable tissue regeneration.
What remains to be tested
The authors call for randomized trials, consistent formulations and longer safety assessments. Those priorities leave questions about clinically meaningful effects and safety across delivery routes, even though the abstract describes some findings favorably.
