I Am Swati, 27 Yrs. 3 Years Back I Had

I am Swati, 27 yrs. 3 years back i had severe acne.I consulted a dermatologist, he suggested isotroin tabs for 5 months untill the completion of my treatment. Acne prob solved. He told to apply Fash foam facewash and suncros aquagel sunscreen (both) everyday twice bcoz of my oily and sensitive skin. I hav been using these two products regularly and Now i do not hav acne prob. Suncros aquagel suits me but it clogs pores every 3 days.I am not using any moisturizer but now i feel my skin needs some good moisturizer. Which moisturizer should i use during the day and at night? I have very fair complexion with little acne scars on cheeks. Also, can i apply suncros aquagel above moisturizer? Please help
