Our  Micro-needle Vita C Spot Eraser Patch contains niacinamide and glutathione. It can use microneedles to form tiny channels on the skin surface, gently remove dark spots, reduce redness, improve skin dullness, and make skin even white. Its application method is simple: after cleansing, dry the face, peel off the mask to expose the microneedles, apply the patch directly to dark spots, blemishes or acne for about 8-12 hours, remove the patch and then apply the regular skin care. Eliminates acne quickly, shrinks pores, reduces spots and blemishes, and makes skin smoother and more delicate.
