A while ago I developed a dark spot in the center of my nose. I'm not sure if "blackhead" is technically the right term for it. It was dark gray, bigger than a pore, hard, and felt like it was growing under the skin. It was so hard and deep that I couldn't pop it, so I resorted to chemical exfoliators like AHA and BHA, hoping they would gradually shed the skin until the spot disappeared. This thing sat on my nose for over year not budging at all. It was so stubborn that I figured the only thing that would remove it was some kind of professional manual extraction. Fast forward to 3 weeks ago, I bought the Clean & Clear Continuous Control Acne Cleanser to deal with a breakout of whiteheads. After a week of using the cleanser once a day, I noticed that the black spot on my nose was suddenly gone. Not just smaller, but gone. I'd had this thing for over a YEAR and it disappeared within one week of using this product. I could never get a good picture of it, but I've attached a picture from Google of a black spot that looks very similar to what I had. Aside from Accutane, I don't think I've ever used a product that had such an obvious effect on my skin. Unfortunately the cleanser didn't help in any other way. In fact it may have made my other acne worse, but it was a miracle worker for this one specific purpose.
