"i am 18 and had mild acne before i started using this product. at least four days after using benzaclin i definitely started noticing results, my face cleared up dramatically. i would wash my face at night, put it wherever i had acne then sleep with it on. if i ever had a pimple i would put the cream directly on it and it would dry out by the end of the day. benzaclin is an amazing product and i would highly recommend it to anyone with acne problems."
