Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern.
As per your complain and presentation of symptoms there can be tow causes of
chapped lips along with eruption of tiny blisters:
1.It can be due to
allergic reaction to some food product or medication or any face or lip cosmetic or may be any irritant present in air and as soon as you are exposed there is allergic reaction.
2. Another reason can be viral infection caused by
Herpes simplex virus causing cold sores.
There is formation of multiple
fluid filled blisters over the lips as well as there is dryness and chapping of lips..
Consult a Dermatologist and get evaluated and he can also advise you to get blood investigation done to rule out for allergies [allergic testing] or viral infection [viral culture, polymerase chain reaction, antigen antibody reaction] and treatment can be advised according to diagnosis..
For allergic reaction anti-allergics like Cetrizine,
fexofenadine [Allegra] a, cold compresses and after ruling out the cause of allergy preventing exposure to allergen is helpful in prevening allergy attack.
For viral infection anti-viral oral and topical medications like
Acyclovir, Valavyclovir etc can e advised.
You can apply thick coat of petroleum jelly or bees wax containing lip balm over lips to prevent dryness and irritation.
Prevent using any lip cosmetics.
You can apply aloevera gel..
Hope this information helps..
Thanks and regards.
