"i am 38 and haven&#039;t had much of a problem with acne since i was a teenager, until i had my first child.  after having my now 2 year old son, my skin just started looking worse and worse and nothing i was doing was making it better. i even bought a clarisonic (made it worse).  so i went to the dermatologist and she gave me acanya and said to use it once a day.  this is only my third day using it and the difference is dramatic already.  not every single bump and mark has cleared up yet, but i would say 50 -70% of my acne is already gone or almost gone.  yes, it does sting a little, i try to not use too much and hope i get used to this or my skin adjusts.  either way, i love this product and can&#039;t believe i didn&#039;t go to a dermatologist sooner."
