Pimple patch for the deep, blind pimple KILLA is a pimple patch with spikes powered by ZitSticka’s signature microdart technology. These tiny microdarts self-dissolve to flood the heart of your early-stage pimple with targeted ingredients, clearing the upcoming drama before it gets real. Each zit patch kit also contains CLEANA swabs soaked in exfoliating, de-stressing ingredients to prime the breakout-prone area prior to application.
