Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain dark spots along with dryness of lips and formation of tiny bumps seems to be probably due to causes like
Allergic reaction, side effects of medicines, bacterial or
Fungal infection, Viral infection causing Cold Sores,
chapped lips due to
severe dehydration, sun blisters etc..
I would suggest you to
consult a Dermatologist and get evaluated and a thorough clinical evaluation and investigations like microscopic examination of scraping of the lips, blood tests etc can help in diagnosis and treatment can be done accordingly...
As of now start applying Petroleum jelly over the lips as it helps in locking moisture over the lips and prevent dryness..
You can start doing cool compresses over the lips..
Apply beeswax containing lip balm..
Exfoliate your lips with a gentle scrub..
Hope this information helps..
Thanks and regards.
