acne
"I have been on this medication for three months now and it is the worst decision I've ever made in my life. I started with moderate cystic acne, my doctor said that doxycycline would work wonders for it, and, sadly, I believed him. Although now I very rarely get cysts, I have broken out severely on my cheeks and forehead in ten to fifteen hard inflamed bumps at a time, and this medication has left immense scarring all along my cheeks that cannot be covered by makeup. My skin is a thousand times worse now than it was when I started. Please don't start this medication. "
