A few years ago I heard that after shaving it is a good idea to wash the face with cold water. The idea is to help close the pores and help keep the skin tight. This can also help prevent ingrown hairs.

I have looked around this site and can't find mention of this. I know I heard this before I discovered this site. I may not be using the search option the right way (operator error)

has anyone else heard this? I was also told to use the cold water before after shave creams to help keep the pores clean. Any other ideas?
thanks!
