I need some help

So I have over exfoliated my skin and now my skin on my face mostly on my nose and cheeks feels like bumpy sandpaper. Also it is very dry and I have small say whiteheads on my cheeks and a lot on my nose. I don't know what to do to make itfeel smooth and soft again. Also I don't want to use any more products on my face or even simple face masks on it. I stopped wearing make up and stopped putting anything on my face...kinda just went cold turkey because I dont want to make it worse. Does anyone knows of anything natural to use to help this heal. Also does anyone know how long it will heal? I have big wedding to attend in 2 weeks and I just want it to heal by then.
