hello all, i have a problem in a small area under my chin, i havent shave there in a while because of it actually, my hair grows away from my chin, but there is a small patch that grows upward( about the size of my thumb nail), now when i shave this i usually get razor burn or red bumps, what is an aftershave solution that can help soothe the red bumps? will an alum block or toner work for helping the skin?
