"i used this for a solid month with an acne pill prescribed by my doctor and it worked fairly well, moderately fast, and overall a good product. however, i ran out of pills and seeing as my skin was mostly clear, had no reason to refill the prescription of pills and therefore use the gel for a couple of months. as foreseen, the acne came back, and so i decided to start using it again. i woke up the morning after i used it to find the applied areas bright red and almost tight. it felt like the worst sunburn i have ever had in my life, plus it itched. though, if you look past the odd sunburn thing that lasted roughly a day or so, when i woke up, all of my acne was gone. i had 4-5 blaring pimples on my nose and were gone by the next morning."
