Hi For the blemishes over the face please use a good broad spectrum sun screen. Use a ph balanced face wash twice a day. use a good moisturiser often. avoid scrubbing or wiping the face often. try a diet rich in brightly coloured fruits and vegetables that contains lycopene and carotene that helps lighten up the pigmentation. If after 4 week you don't see kmp improvement please contact a dermatologist who can examine you and prescribe the appropriate skin care products
