Help! what is wrong with my skin?

I wear more foundation on my face because my skin is so pale I wear more then most girls but, I don't know if this could cause it I have been doing this for 2 years now. I always wash my face thoroughly every night before I go to bed. When I washed my face it felt a little uncomfortable, then random very tiny bumps all over my face popped up and there's red blotches. Could this be because I wore a lot of foundation over the years, or something else? :(
