So, this is a wonderful product for acne, especially whiteheads. The patches come in three different sizes and work by drawing out the oils and puss out of the pimple. These will NOT make your pimples disappear BUT they do remove the oils, dirt, and nastiness from your acne to increase the turnover rate of your skin repairing. Make sure to also put one on completely clean skin and try to leave it on overnight to get the most benefits. Very affordable and effective. I would buy again in a heartbeat.
