Where does the dryness of the lips come from?
The lips are highly vulnerable: with no sebum or
natural protection, they dry out easily.
Cold, dry air, saliva and certain drying treatments
can leave lips very dry and damaged, as the skin is extremely thin. They feel tight, burning, and tingling, with a constant need for relief. The signs are visible and pronounced: flaking, dead skin, redness, and more. Even moving the lips becomes painful.
