whiteheads and redness

im 15 and i have whiteheads on my nose and cheeks by my nose but not alot. my face is also red there but not my nose. the redness on my cheeks looks like irritation because of all the topicals and cleansers i've been using on my face. almost all of the products i've used were salycilic acid. when i used to wash my face and put all that stuff on my face it didnt really help.
since about two weeks ago i decided to not wash my face for a while like water water and all those other guys. i noticed my cheeks arent as red or oily but the whiteheads are still there and a little red. do you think i should wait another week or two to see if i see more improvement?
