"at age 36, my acne started to come back after a stressful time. it was concentrated on my chin, and was relentless. new cysts every single day. my doctor prescribed tretinoin cream plus an oral antibiotic (doxycycline). i was so nervous about starting because i read so much about it getting worse before it got better. but to my amazement, after just a few days i started to see drastic improvement. not a single new pimple, the existing ones healed quickly, and scars are fading fast. i&#039;m shocked (and extremely happy!) at how well this worked for me."
