Does oral glutathione work for skin brightening?

The evidence is moderate but real. Multiple clinical trials show visible skin lightening with 250-500mg daily over 12 weeks. The effect is more noticeable for tan and uneven tone than for genetic skin colour. Intravenous glutathione is more effective but carries significant health risks and is not recommended.

How long does glutathione take to show results?

8-12 weeks of daily use for visible results. Most users see subtle brightening at 8 weeks and more noticeable improvement at 12 weeks. Discontinuing use reverses the effect over time.

Is glutathione safe for Indians?

Oral glutathione at recommended doses (250-1000mg) is considered safe for most healthy adults. Side effects are rare and mild. IV glutathione has documented serious risks and should not be self-administered.
