Do NOT peel that skin on your top lip, it's not "just" dead skin...that is the beginning stages of EC. if you rub it off it will grow back and get worse...you need to let your body take it off on its own...that is don't touch it. That is there because it is protecting the skin underneath growing which has started getting EC even though it doesn't appear to have it...it does. So just be careful, don't rub it and you should be fine :)
