I only exfoliate my lips when they are dry and peeling. I use a bit of Vaseline on an old toothbrush and lightly rub them. I found it works best after a shower. That's pretty much my only lip routine besides lip balm. I like moisturizing lipsticks and glosses, I hate the dried out feeling. My fave lip balm is Fresh Sugar Lip Treatment SPF 15 http://sephora.com/browse/product.jhtml?id=P570... which is ridiculously expensive, so I only treatment self about once a year. I only apply it once a day, the rest of the time I use Lobello from the drug store. Great question, i am interested to see what other people are doing for their lips ...
