Hi doctor, I am 28 years old woman. I have been biting my lips and often tear off the dried skin of my lower lips from my childhood. So from the childhood my lower lips started turning pale and now became white, slowly leading to depigmentation in my lower lips. When I was pregnant (2 months), patches increased. I have no other patches like this in any other parts of my body. Doctors asked me to abort since I got German measles when I was 2 and half months pregnant. It has been 5 months since abortion. After abortion also patches increased even inside of my upper lips. I have sinus problem, so often I breathe through mouth only. My office and bed room in my home are also fully air conditioned. I went to a dermatologist and he gave my tablet named Patchex for one month and asked me to apply a lotion named Vitibex. He also gave an oinment for mouth ulcer. I have oral herpes infection and often I have cold blisters in my lips. But when I was pregnant and after getting that German measles and till now , I have no cold blisters. I am afraid whether it will be vitiligo. Please suggest me whether it is a vitamin deficiency and what are all the foods I have to take for repigmenting my lips.
