Hi there I understand your concern...you must also consider that there are several skin diseases which can pigmentation on the face. Also the use of steroid creams also can cause pigmentation over the face. Hence it best you consult a dermatologist. For now use a sunscreen like suncote gel morning and afternoon. And a face wash like ahaglow-s or spongysal face wash for oily skin. Wash your face regularly at least 2-3 times per day...

First you should rule out for skin diseases, allergy etc.Take aragwadarishtam, Hingula bhasma tab, eladi cream for external application.Wash your face with green gram powder daily trice. Apply kumkumadi tailam before going to bed.
