"being almost 30 and having cystic acne i began taking this as a last result. i tried all skin care lines....found myself using clarins and my skin improved but still i was oily and breaking out on my neck and cheeks.  after a couple of weeks i noticed i wasn&#039;t waking up with what seemed like a thick layer of oil on my face. i began to break out less and less. my dermatologist upped my dose and now my painful cystic acne is gone and my skin feels great. although i find myself very parched at times and you must watch your salt and alcohol intake. i like this medication."
