Hi, masyi rI ,answer your health queries right now ? Please type your query here... sir, i have developed black colouration on my lower lip its like a small patch with white tiny spots scattered over it. i hv consulted doctor. he said there is nothing to worry and gave me sunscreen lip lotion to apply and one more cream to be applied over the affected area at night. sir i applied both the lotions and as i cldnt find any difference i left applying it. can you tell the reason why such a black colouration occurs and how it can be cured. this colouration started about 5 months back.
