How we score →Yay
3 experts · Moderate agreementWhat the gurus are saying
This serum visibly fades hyperpigmentation through a potent combination of high-dose glutathione, multiple vitamin C derivatives, tranexamic acid, and other brightening and antioxidant actives, all at a genuinely affordable price. The one thing to keep in mind: twice-daily use is needed to maintain the benefits over the long term. The price point makes that consistent routine easy to stick with.
