Made with microneedle technology, the Revolution Skin Zap Patch Microneedle Spot Patches reduce the appearance of blemishes in as little as four hours. n Suitable for all skin types, the gentle but effective spot stickers feature a powerful blend of salicylic acid and hyaluronic acid, working to exfoliate and remove impurities while hydrating and soothing the skin. A hydrocolloid layer helps to absorb excess oils and provide a protective barrier, ensuring strong adhesion to the skin so you can wear under makeup or overnight.
