I have these bumps all over my forehead, it's not even pimples/acne.

It's like black heads and such, but there's a lot!

My friend said he used to spray cologne on his forehead to make them go away, does this really help?

I would think that it would irritate them more!

No! I tryed, and the chemicals in the cologne aren't meant for skin contact. some cologne can burn your skin if you put a lot. Try toothpaste =)! Toothpaste is the best huse-hold acne disposal.
