Huum, it`s hard for me to explain you with my english, but ok i try. And I think you mean face-shaving or...?
I shave my face alway under shower. The warm water makes your skin/hair very soft. Then i shave under the runig water my face with a Wilkinson. I never have iritations. When i`m finished, I dry my face by air. Then I us a cream from Vichy. Thats it I hope you understand something
