I am a 37 year old women that never had acne as a teenager, but as an adult my back chest and neck were awful. Deep Blackheads & large purple sore pimples. I have tried everything under the from over the counter to Proactive and have had no success except extremely dry skin on my back. I seen this on a commercial and bought it the next time I was at CVS. Used it that night 5/15/2008 and again last night. Tonite my back looks the best it has in years. I chose to use it every few days instead of everyday since my skin is dry from the other products I have tried and the packages advises to do so if it drys out your skin. I am so pleased and I can't wait to be able to wear a backless shirt or dress for my husband again. ONce again I can feel beautiful because my skin looks as good as I do.
