The diet didn't help as much as I thought it would. What seems to be helping the most is the peroxide/baking soda brushing. My lips are peeling in spots. The skin that isn't peeling is very hard and tight. Sometimes it's hard to smile. I've tried putting lemon juice on them but I'm not sure if it is helping. I'm also drinking lemon juice, but am still looking for results. I apply castor oil too.
