Cheap Drug Store Skin Care Routine for a 13 year old?

I'm thirteen years old and I don't have the wealthiest parents in the world. I do get the occasional 3-5 pimples at a time and I have blackheads all over my face. At the moment I'm not very consistent with cleansing my face and I use St. Ives Apricot Scrub 1-2 times a week and the Neutrogena Wave everyday. (again not very consistent) I have very dry, sensitive skin so please don't recommend any harsh products. I need a CLEANSER, TREATMENT, & MOISTURIZER. Please and thank you. (:
