Texture of my skin has changed after birth

I never had any problems during pregnancy but I notice after I gave birth my skin (mainly face) feels different. When I first noticed, I thought it just felt dirty since I hadn't been able to wash my face but even after I washed it felt rough like it was dry. However, it doesn't appear dry and even after moisturizing, still feels the same. I'm at a loss. Has anyone gone thru this that can shed some light and/or helpful tips.
