"in my younger years i had never experienced any sort of acne. when i turned 23 is when it started (i&#039;m now 30) so it was time to make a change. i should also say that my breakouts were only on my chin but were cystic. i went to my doctor asking her to put me on acutane but she insisted that i try doxycycline first as it can give ultimately the same results as acutane. she started me on 100mg 2x a day along with the topical benzaclin 1x a day (in the evening) i have had virtually no side effects and i know a lot of people have been saying that they broke out in the first few weeks of being on it, this did not happen to me (yet, anyways). i have been on the medication for 2 1/2 weeks now and i&#039;ve noticed a vast improvement!"
