Acne
"Its been over a month using the over the counter.  I posted previously.   I had started out using once every three days and then went to every two days to make sure no issues.  Skin got very dry at first. 

Apply each evening about two hours before going to bed.  In the AM I apply Neutrogena Oil-Free Moisture with Sunscreen SPF 35 and re-apply as needed. 

Had several blackheads mature during the month.  Some were under the skin surface.  All gone.  A few whiteheads.  Skin has calmed down considerable.  Skin seems healthier. No longer use Benzoyl Peroxide."
