Dark spots on the face can last a long time, even after the original skin issue gets better. Sun exposure, past fungal infections, acne scars, irritation from using too many creams, or conditions like melasma can all leave stubborn marks on the cheeks and forehead. Since you have already tried different medicines and creams, the spots you see now are likely due to pigmentation rather than an active infection. Using sunscreen every day is still important because even a little sunlight can make facial pigmentation worse and slow down healing. Try not to rub your skin, scrub too hard, or switch products often, as irritated skin can get darker. Ingredients like azelaic acid, niacinamide, kojic acid, or retinoid creams are sometimes used for pigmentation, but these treatments should only be started after a dermatologist checks your skin. Some people see better results with chemical peels or laser treatments if creams are not enough. If the patches keep spreading, become uneven, or get darker, consult your doctor.
