Doxycycline
"Last year I stated taking medication (not doxycycline) and I helped very much. However, if stopped working as well before I saw any real results. I've been on doxycycline for about a month and my skin is the worst it's been in a long time (mainly on chin and cheeks) nothing I'm doing is getting rid of it and it's leaving big scars. After reading this I have decided I'm not going to give up yet. If they don't work within 2 months I will seek further advice and help."
