Laser Treatment for Razor Bumps and Chicken Skin?

I have this skin condition since I was about 14 or 15; now that I'm 20, it still hasn't gotten any better. I went to a dermatologist before, he roughly examined it and said it was "chicken skin" (Keratosis piliaris), but I'm not sure if it is, because this happened after I started shaving. I shaved in the opposite way of the hair's growth, so I think it might possibly be razor bumps (Pseudofolliculitus barbae). For either one, I was wondering, is there a cure for this disorder? Will any laser treatment or laser hair removal help remove these from my arms and legs?
