"i&#039;m 14 and i started taking it about 1 1/2 weeks ago. at first. my acne got really bad. all of the pimples were coming to the surface. now, after almost two weeks, i don&#039;t have any acne. warning: don&#039;t start taking this a few days before a big event! take it about 3 weeks before so all of your acne will be gone. also, don&#039;t take this if you are going to be out in the sun for a long time. i had to learn this the hard way. it makes your skin sun sensitive."
