Thank you for query.Acne depend on hormonal effects, sebaceous gland secretion etc.It gradually reduces with age usually in both severity and appearance.So only good control can be achieved by regular face wash with cleanser,topical keratolytics like retinoic acid creams or salicylic acid creams and antibiotics like clindamycin, if necessary oral antibiotics.treat if any dandruff with ketoconazole shampoos.Some peeling does occur initially when you use keratolytics .Apply them only in night .If she does not get adjusted/ to it by a week or ten days with the moisturisers also or becomes severe you can shift to milder dose or change topical with consulting your dermatologist for management .else get back to us directly.Dr Bharatesh D Basti Dermatologist
