I know ur serious like, but i have to. Want me to smack you? that will fatten ur face up. Nah seriously really there isn't no way you can fatten your face up unless you put on bodyfat which dont dont want if ur building and toning. Cant change ur genetics, and Cougar is being sarcastic but his comments do have slight value, maybe you could change ur hair style so its more Buffed out, the hair would make ur head look bigger.
