Livaclean-Superstar Pimple Patches These pimple patches are made from hydrocolloid, a gel that absorbs excess fluid/infection and protects the skin from bacteria and debris. The patch creates a moist environment that helps blemishes heal much faster. As the patch absorbs fluid, it turns white and should be replace once you begin to notice the change. These star patches are made to be a cute way to cover blemishes while treating them at the same time!
