What type of acne product should i get HELP!!?

Ok, I have been using oxy cleansing pads, clean and clear astringent bottle , and clean and clear persa gel 10 for all over a year now. They all worked really good and for like the past two months they havent been working as well. Before i started using those products i had terrible acne. The problem is that these products still help just not as much as i want them to and if i switch products id have to wait a couple months for them to start working PLSS HELLP ME
