Nexcare Acne Patches are hydrocolloid patches that act like a sponge to absorb the oily secretion, fluid, or pus from a pimple. The patch acts as a layer of protection over a pimple to reduce hand contact and help prevent infection. Transparent, you hardly know it is on. Works on a variety of skin types and are a non-medicated, non-drying way to absorb oil from clogged pores. Helps reduce the urge to touch and pick at the blemishes.
