Replying to @The Real Skin Nook Glutathione has always had one very obvious problem the smell. That strong sulphur odour comes from the sulphur containing structure within the molecule itself. But Faded gets its smell from glutathione, an ingredient thats super effective at reducing the appearance of discoloration in week Glutathione has a cysteine chain that causes it to have a sulfur like Glutanex Deo Glow Balm with Glutathione Beauty Glimpse by Maria Rotten egg smell but thats how you know its REAL glutathione This ampoule is not here to smell pretty its here to WORK. helps reduce dark spots & pigmentation boosts skin vitality & glow
