Made with microneedle technology, the Revolution Skin Microneedle Hydrocolloid Spot Patches reduce visible redness in as little as four hours. Developed for deep, under-the-skin blemishes that may not have a head, the hydrocolloid patches are made with non-painful microneedles to support multi-level action, while salicylic acid helps to visibly refine and clarify the skin. Hyaluronic acid supports the spot stickers with its hydrating, skin-soothing benefits, leaving the complexion looking clearer with less noticeable impurities.
