"i am a 44 yr old female that has suffered yrs. from cystic acne and rosacea. my wedding was coming up and all i could worry about was if i would have a huge ugly red bump on my face on my wedding day. i was stressed already and we know that play&#039;s role on how our skin. i decided to see a dermatologist a month before my wedding. she put me on doxcycoline 100mg x a day. i took only 100mg when i got it because i&#039;m always worried when i start a new medicine. wow!!! is this all it took to rid myself from these painful ugly cyst? you bet!. i have not had any since i started the doxy, and i&#039;ve been on it for 8 months now. no cyst or acne on my wedding day! and none since. this medicine gave me part of my life back. so happy!."
