I only give this product a star rating of two because it creates other problems. My 13 year old daughter was on Benzaclin for eight months. She had break out in the T-zone are with rednes. We decided to use this product when her pediatrician recommended it. Within two weeks it cleared her skin and the skin was back to being beautiful. However, after 4-5 months I noticed she got one pretty big pimple on her cheek that would take forever to go away. A month or so after that she got another big bump on her nose. Once that cleared her skin stayed clear until the eighth month mark. Then on one of her cheeks she began getting these huge bumps that got bigger and bigger. These all looked like clogged pores to me. I was getting irritated so took her to a dermatologist who said she had clogged pores. He put her on the Differin Gel. We are now five weeks into this product and we hope to begin seeing results soon! I am a little leary of all these medical products because I am not convinced they work long term. I do believe the Benzaclin helps in some ways but creates problem skin in other ways as with the clogged pores. I believe pores are meant to breathe and keep the oils flowing in order to keep the skin healthy. If this product does not help I will probably return her to the Skinceuticals and Mark Lees line of products that she was using before because at least I know they are gentle. Some of these medical products are just too harsh for some skins to take and I do wish the dermatologists would recognize that.
