"i&#039;ve had acne problems since the 4th grade and have since tried tretinoin, benzaclin and dalacin t which did not help me very much. i gave up prescriptions for the last 5 years using otc benzoyl peroxide when i suddenly had the worst breakout of my life (i think from stress) with cystic acne. family doctor gave me differin xp gel. i&#039;ve been using it for 1 month and my acne has dramatically cleared up. i did not purge at all (maybe got 3-5 small pimples) and i peeled once while swimming outside. i was also prescribed 333mg erythromycin tab by a dermatologist but did not take it yet as it seems differin has already cleared me up. 

i did skip a few days and used 4 dot sized amounts instead of the recommended &quot;pea-size.&quot;"
