Question: why do my lips burn when i lick them?
Answer: Lip dermatitis, or eczematous cheilitis, is a type of eczema, a skin condition that can cause severe flare-ups on your skin. The cause of eczema is often unknown, but it may be linked to an allergy or an irritant, like frequently licking your lips. Genetics may also play a role in developing lip dermatitis.
