My skin is a mess, break outs, redness, clogged pores, wrinkles. What can I change?

My skin used to be great but it all changed throughout pregnancy and breastfeeding for the last 2 years. The hormonal changes throughout this time and having to watch which products I use, my skin is now a mess. My t-zone gets oily, I have eczema patches, redness, regular breakouts and clogged pores. My wrinkles and fine lines are obvious and make up sits on my skin. I look dull and have lost any glow.
