Hello, Welcome to healthcare magic. I understand from your query that you are having pigmentation on your face. From your description, it could be a condition called as melasma. I would recommend you to use a face wash twice a day ideally a one containing glycolic acid as it helps in exfoliation and to even out the skin tone. The most important product will be a sunscreen. Half an hour before going out apply a sunscreen and reapply it every three to four hours. You may apply a compact powder over the sunscreen so that there is a matt finish. At night you may apply a lightening cream containing kojic acid over the patches before going to sleep. You may consult a dermatologist practicing cosmetology for few sittings of chemical peels for faster improvement. Hope this helps you. Take care.
