acne
"I switched to doxycycline for my acne after Solodyn (which reduced the acne I was getting by about 50%). Prior to taking doxycycline, I had borderline cystic acne and lots of PIH/redness. Within two weeks, a lot of my acne sunk into my face and went 'inactive.' I still get about 5% of acne that I got prior to taking any medicine, but no more lingering cysts, just small pimples. I feel that doxycycline has been very effective for me, and the only side effect I have noticed some slight photosensitivity/higher chance of sunburn (this would be the case with any antibiotic). I've been on doxycycline for almost 3 months and plan to continue taking it. Now I'm just dealing with PIH!"
