Best acne treatment

At my wits ends so many different products and depending on your own particular circumstances, which one will work best for you? I was doing fine controlling any kind of outbreaks then after quite  few years at the same job I switched jobs. The new place I work at has a lot of fine dust created by different products. Most of all cardboard. Washing up on my breaks is a constant habit. The next step is finding the  best acne treatment for myself because my old treatment doesn't seem to be working anymore.
