Positive findings : Systematic review found that 500mg daily oral glutathione and 2% topical glutathione could brighten skin in sun-exposed areas Well-tolerated with good safety profile in clinical studies Consistent improvements in melanin index measurements Limitations of current research : Evidence still considered inconclusive due to quality of studies and inconsistent findings Small sample sizes in most trials Short-term studies with limited long-term data Variable results between individuals Scientific Gaps Several important questions remain unanswered: Optimal dosage and treatment duration Long-term safety of prolonged use Maintenance protocols after achieving desired results Individual response variability factors How to Use Glutathione Safely for Skin Starting with Oral Supplements Most evidence-based approach for beginners
