"i have had acne since i was 15. i am now 24 and still have what i consider to be moderate acne. a few deep painful ones, whiteheads, blackheads, and little clogged pores. i have been taking this for a little over a week. the redness is decreasing and my skin is feeling smoother. still have a few painful pimples, but they seem to be healing. i can tell it&#039;s getting better. i am on 100 mg once a day, but i think i will up my dosage. i have had no side effects...i was worried i would based on what i read. it&#039;s possible they will creep up later, but so far, nothing! i am pleased as of now."
