Without external examination it is very difficult to confirm a diagnosis,but the various possibilities for yellowness of the skin around nose and mouth are liver disorders,anemia,perioral dermatitis,post inflammatory hypopigmentation ,tinea versicolor,tinea alba(fungal infections)and impetigo(a type of skin infection).
I sincerely advise you to onsult a dermatologist and get yourself evaluated .Also discuss the above mentioned possibilities with him.
Hope it helps.Take care and pls do keep us posted on how you are doing or if you have any additional queries.
