1 day post op, woke up with whiteheads allover face. Did I mess up my skin by getting sun exposure after microneedling?

I got microneedling done yesterday and was driving all day after. I woke up this morning with whiteheads ALL OVER my face, specifically my cheeks and chin. My skin is skill very inflamed and rough but I heard this is normal... although it hasn't subsided since yesterday. Could the whiteheads be caused by my pores being clogged because of using a thick cream, or is it due to sun exposure? How can I clear it up, change my routine, or will it go away on its own?
