I just started using Clinique 3 step system and now I'm breaking out?

Before I started using the system I had a few pimples but not too bad, but now my face is breaking out worse than ever. When I first got it they gave me the dry combo toner and cleanser and the dramatically different moisturizer but my face was getting really dry so I went back and got the toner and cleanser for very dry to dry skin. I also just started taking zoloft and xanax for my anxiety but I don't think those would make my face break out. I was thinking maybe my skin just needs time to get used to the new products I'm using because I completely switched my skin care routine but I don't know…
