Fast-acting Microdart patches help rapidly improve the appearance of discolored spots. Why Microdarts? Miniscule, self-dissolving darts - saturated with brightening niacinamide, licorice and Vitamin C, plus hydrating hyaluronic acid and cica - precisely target hyperpigmentation for fast, visible improvement. Our signature Microdart Melt-Tech Technology boasts 176 Microdarts (more than any other brand!) that self-dissolve deep into skin to deliver ingredients that precisely target dark or red spots. Our lab spent months perfecting the levels of sharpness - zero pain, but effective! - and adhesion to deliver you best-in-class innovation powered by science. Our no-color, transparent patches can be worn overnight or under makeup. Apply every 8 hours as often as needed. This formula contains 4% niacinamide cocktailed with licorice and Vitamin C to help visibly improve the appearance of discoloration. Meanwhile, skin is flooded with hydration thanks to the hyaluronic acid base in the formula. K-Beauty star ingredient, cica, provides soothing benefits to help skin recover while staying calm. Melanocytes can stay overactive if skin is dehydrated or irritated - this smart formula does not just use brightening ingredients, but combines with hydrators and soothers to tackle post-blemish redness. The unique sticker shape makes it subtle to wear.
