Summary

This study tests whether a daily fizzy drink containing glutathione can safely lighten facial dark spots and improve skin radiance. Sixty adults with hyperpigmentation will take either the active drink or a placebo for several weeks. Researchers will measure changes in pigmentation, skin glow, elasticity, and hydration using specialized devices.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Glutathione (as effervescent tablets)
What this could lead to: If it works, this could point toward an over-the-counter option for reducing facial dark spots and evening skin tone.
What could go wrong: This is a small, early-stage trial with only 60 participants, so results may not apply to everyone. The placebo group helps check if any improvement is real, but the effect may be modest.
