What does master chifes face look like from halo

There is no "face" of Master Chief. Bungie does this on purpose to help keep the player immersed in the series, and make it feel more like it's them fighting the covenant, and not some random guy they never knew about before the games. The books do briefly mention that he has brown hair, and freckles on his face, but this was when he was only six years old, and has likely changed very much.
