question: iam 33.5yrs old, female from india.. my skin was very oily in teenage and twenties but now sometimes i feel too dry. recently i got some kind if itching on my face and also discoloration and patchy skin on the forehead . also there is pigmentation on the sides of my nose and around lips and chin and lots of whiteheads and blackheads too. i saw a doctor and he prescribed sun ban for day time and carofit ultra for night. how long can i continue using these. because i feel better now.. can i use the sun ban lotion always . should i be using any other moisturizers,, if yes which is the best sunscreen plus moisturizer for my skin which is quiet sensitive now a days??
