"i&#039;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&#039;ve seen an improvement within 3 days of use. take it with food and you will not get sick! i&#039;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&#039;t get discouraged!"
