Wudhu

Q: Is wudhu valid if someone wrote on their hands with pen and didn't scrub it off?

Q: I am in a state of ritual impurity and water is available, but I am unable to perform ablution due to shyness and lack of time.

Q: I have a lot of whiteheads on my nose. From what I know these are clogged pores. After ghusl, because of the heat of the shower, the white heads and clogged pores comes closer to the surface of my nose and I can brush some off with my hand. It's not watery. Does this break wudu like pus would? Or does it just count as dirt of the body.
