As a mother of a teenage boy and someone who had also suffered from acne myself, I highly recommend ProActiv. As a teenager, I took every antibiotic imaginable for my acne and none of it worked...it only weakened my immune system. When I was 22, I took Accutane, the strongest (and most expensive)treatment out there, of which the side effects can be horrendous and can severely damage your liver--only for my acne to return in my mid-20's. That's when I found out about ProActiv. At around $40 a month (it comes in a month supply)it is highly effective and is the ONLY thing that got rid of my acne. My 15 yr. old is now using it and his face has cleared up as well.
