Skin Breakouts

I haven't been wearing makeup since I had my baby, but I recently went back to work on the weekends and I like to look presentable so I do wear full face of makeup, but it is taking a toll on my skin... Not sure if it's the primer I'm using or just the fact my skin isn't used to it.

But what are your recommendations to keeping clear skin? I do still want to wear makeup... What are your tricks? Any cleansing products? Do you think a mask once a week would work? Should I try a toner?
