Heres exactly how I ranked these glutathione contenders: Week 0 : Baseline photos (consistent lighting, no filter) Weeks 1-4 : Daily use (AM/PM), tracking glow + hydration Weeks 5-8 : Dark spot measurement (ImageJ software analysis) Weeks 9-12 : Long-term fading + skin barrier health Metrics : Melanin index reduction, user satisfaction, value/ Sample Size : 5 skin types (oily, dry, combo, sensitive, mature) Controls : Identical SPF/moisturizer routine across all tests Result : Only glutathione facewashes hitting 60%+ dark spot reduction made the top 10
The difference is astounding and this means I have it, without needing to pay to prove it
