"i have previously taken doxycycline before at the age of 14 due to acne and i found it really effective for about one year, afterwards i went on a course of roaccutane for 6 months and my skin was crystal clear. about one year ago my skin started to break out again. really bad breakouts and in such noticeable places. i am 18 now and i have started on a course of doxycycline again and this is my first week of treatment, i am already noticing results. i have had a few small breakouts but nothing like before. my skin is healing quicker and the redness is slowly going away. i expect to see better results around the one month stage but so far i am happy with my results."
