"i am a teen who suffered from borderline mild-severe acne. my dermatologist prescribed epiduo. nothing over the 6 weeks. she then put me on doryx with it. i fell in love with my skin after about a week. it dried up current problem spots and never got a breakout. however, do not take in calcium while on this. the medicine will bind to the calcium and will not take effect. whenever i eat a good amount of cheese, milk, or dairy, i break out. you should experiment with your diet if this medicine does not work for you."
