Skin needs to be roughed up on occasion -- at least the dry skin that's ready to retire. Your skin is continually generating fresh cells that move up to the surface. Old cells can stubbornly cling to skin via air pollutants, makeup, excessive oil, heat and the like. So seek aid from a heavy-duty exfoliator -- the invigorating body brush. Give your skin the breathing room it yearns for and go for a periodic deep clean.
