"only on my second week of treatment but its not looking so good. i got it to treat some cystic acne on my back and my skin cleared up quickly the first week. however i&#039;m tired all of the time, and the cystic acne&#039;s coming back with a vengeance. just broke out with a line of huge pimples down my lower back which has never happened, and some on my face, all of which are very painful. i&#039;ll continue the treatment for a few more weeks but so far things aren&#039;t looking good."
