What to do if i had really chapped lips for almost a week, any treatment?

Chapped lips : The tendency for most of us is to lick our lips to moisten them. This is the first thing not to do! try to avoid licking your lips. You can also use the lip balm of choice. Lipstick isn't designed usually to rehydrate lips, so stick with stuff that is. One of the more effective is vaseline. You just have to keep reapplying it. Try chapstick, blistex or carmex. There are others, too.
