"i am female in her early 30&#039;s - about 3 years ago i developed adult acne after years of relatively clear skin. benzyol peroxide had been my miracle acne product but then i developed contact dermatitis and could no longer use it :( i honestly could not go more than a day without a new pimple developing despite using other prescription acne grade products, vitamin a as well as expensive spa treatments. i have been on aczone about a month and have had instant results, i have not had a cystic pimple since. i still get blackheads and have milia on my chin/jawline but no pimples/whiteheads/cysts to speak of and have had no issues with dry skin. the product is pricey but i will save in the long run not wasting my money on others that don&#039;t work."
