After the age of 30, I still frequently encounter face breakout. Although each time there are only 1-2 pimples, they are relatively large. If left untreated, one might have to endure discomfort for more than 2-3 weeks. At first, I wasn't sure if it was necessary to use a product costing $200 to solve my occasional skin problems. After reading many reviews, I decided to give it a try. This product really works as it claims. It takes effect the next day. Especially for my relatively large pimples, I apply it every night, and the swelling will subside significantly the next day. Pressing on the pimples doesn't hurt as much anymore. Moreover, it's very convenient to use. Each pimple only takes 8 seconds to treat. For extremely active pimples, I usually do two treatments, which is 16 seconds in total. This can accelerate the reduction of the pimples. In fact, I did achieve this.
