"i have been using epiduo for about 6 months and i&#039;m in love with it. i travel a lot and even so much as got samples from my dermatologist since i don&#039;t check my bags and because of the airline restrictions. i haven&#039;t had any bad reactions and noticed just after a few days of using it a huge difference in my skin. i have tried several acne regimens from clean &amp; clear to proactiv and nothing worked until i started using epiduo."
