Hi, After going through history given by you, I feel that most probably you may be having melasma. It is a facial melanosis occuring on face,forehead and nose. There may be some influence by hormonal imbalance. Sunrays might exacerbate the pigmentation. It is a cosmetic problem without any symptom. If you feel embarrasing, you may consult dermatologist. I would like to recommend following line of treatment... - tab tranexamic acid twice a day - tab vitamin C twice a day - glutathion containing tab once a day - kojic acid containing gel on patch twice a day application - sunscreen application while going under sun - cleansing the face with facewash containing glycolic acid and kojic acid -have patience I hope this might help you.. Thanks. Dr. Ilyas Patel MD
