What do i do to get my skin perfect ?

Im 19 and my skin isn't bad i just have acne above and around my mouth and some on my forehead and i don't know what to do to get near perfect skin. Im very self conscious about my skin seeing as all my friends have flawless skin. I use cleansing wipes and Aloe Vera moisturizer twice a day everyday and I have been taking two teaspoons of Cod Liver Oil for the last few weeks but it doesn't seem to be working. Anyone have any idea what to do to help ? Or do i just go to the doctor ?
