"i had fairly mild acne, but when i went to the doctors it had been flaring up, and looked quite bacterial. when i first started using it i was happy, as it appeared to clear up my spots in less than a week, but after maybe the third use (i was using it once per night) i noticed my skin was very dry, but was not too worried as this is a known side effect. unfortunately, the dryness only got worse, even when i used it after moisturiser, and even stopped using it. it got to the point where my skin was so dry and irritated that it was bright red, and i could barely splash water in my face without it stinging. if i used cleanser my face would sting so badly i cried. it took 3 weeks to clear up, and i was left with chemically burnt skin."
