Hi dear , As per your query you have hyperpigmentation marks on your face due to burning . Well such kind of marks takes times at least a month with appropriate treatment . As you mention that your doctor has suggest you momeka cream which is corticosteroid cream and should not be used for long period of time because of its side effects . I would suggest you to wash your face with mild soap twice a day and apply kojivit cream , exfoliate your skin twice a week and apply vitamin E oil at night before going to bed . Also protect your skin from excess sun exposure as it can worsen the condition . It condition doesn t get improved in a month then consult dermatologist again for proper examination . Doctor may recommend chemical peeling or dermabrasion depending upon the severity of condition . Hope your concern has been resolved. Get Well Soon. Best Wishes, Dr. Harry Maheshwari
