Hello, Welcome to healthcare magic. The hyperpigmentation on your face as described by you could be due to 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. Continue the creams that you have been using. You could consider chemical peels like glycolic acid peels and retinol peels. You can get these done by a dermatologist. Have healthy diet consisting of anti oxidants ( fruits and vegetables). Hope this helps you. Take care.
