acne
"I'm 21 years old and have been on every acne medication under the sun. 6 years ago I went on Accutane for 3 months and it worked wonders. Completely clear and amazing skin. Being a teenager and going on Accutane meant that there was a good chance my acne would come back - well, it did (about a year ago). Not terribly, but enough to really bother me. My lovely dermatologist put me on doxycycline and it is fantastic! I've seen an improvement within 3 days of use. Take it with food and you will not get sick! I'm not talking about a small snack - take it with a substantial meal! I know that everyone is different, but if you want clear skin than you need to stick it out -- Don't get discouraged!"
