Hi.. Welcome to HEALTHCARE MAGIC. I have gone through your query and can understand your concerns.. As per your complain Vitiligo is a skin disease in which the pigment producing cells known as Melanocytes are destroyed in certain parts of body leading to depigmented white patches.. In case if you have white patches over your lips that are diagnosed by your doctor as Vitiligo patches you can consult a dermatologist and get evaluated and a clinical examination and investigations like Blood tests and biopsy can be helpful in confirmatory diagnosis.. In case if vitiligo is confirmed as the cause you can be advised to apply Steroid based ointments and creams over the lip to repigment the skin.. Psoralen can be advised to be taken orally as well as applied over skin.. Creams containing Fibroblastic growth actors and chemotactic agents that can initiate formation of melanin producing cells like Melgain can also be advised.. You can also be advised to get treatment like Lazer treatment and PUVA light therapy.. A non conventional treatment agent known as Ginkgo Biloba that is a herb has been shown to help in regaining the pigmentation and hence can be advised.. You should also take multivitamin supplements and take a nutritious diet.. Hope this information helps.. Thanks and regards. Dr.Honey Nandwani Arora.
