Hi, You seem to have facial melanosis. It may be due to tanning effect by sun exposure. Other causes like vitamin deficiencies and internal or hormonal diseases should be ruled out. To improve skin color of your face, you protect your face from sun. You may apply sun screen cream,gel or lotion like sun mask aqua gel. You may take glutathion,nicotininc acid or vitamin C in proper doses. Apply kojic acid containing cream or gel at night. Wash the face with facewash containing kojic acid vitamin C.You might feel better after few months treatment. I hope you got my answer. Thanks. Dr. Ilyas Patel MD
