I need advice on a skin care routine?

over the past few weeks i've been breaking out like crazy. every day i would wake up with a new surprise on my face, either a big white head or a deep pimple that would hurt. i have scarring from alot of the pimples now and it is very severe on my chin. since the beginning of this year i've used olay clarify & cleanse daily scrub.. i guess it stopped working..? i dont know. i went to the drug store yesterday and got 4 new products and wanted some advice on a good routine. i'm not sure what to try or if i should use 2 at night.. or what. i purchased clean & clear morning burst, ( i will probably use this in the morning every day ), neutrogena deep clean relaxing nightly cleanser, neutrogena oil free acne stress control power clear scrub, and st. ives apricot scrub. any tips on what to use and maybe a routine i can use daily? any advice would be greatly appreciated. :) thank you !
