"i&#039;m a 19 year old female and my skin was perfect until i turned about 17. then it still wasn&#039;t too bad, a couple of pimples every now and then. it started to get worse over the last couple of months, mild acne, so i was prescribed doxycycline 50mg once daily. i have been on it for three weeks now and my skin is worse than it has ever been. my face is covered in huge red sore bumps and i have scarring everywhere. i wake up with at least three new pimples a day. i am about to give up on this stuff because it has made my skin 10 times worse than it ever was. i have heard it gets worse before it gets better but i&#039;ve read it usually only takes 2-3 weeks to see improvement but it doesn&#039;t look like it will be getting better anytime soon."
