I found this info at IGN for a further description of the new look of Freddy "Overall, Freddy's appearance is less that of the freshly-burned killer and more like a man who's had a short time to heal. The skin is pulled and misshapen, flesh-toned in places and red-raw in others. Patches of green-rubber suggest areas of deeply worn sinew along the cheeks and jaws, executed in post-production, suggesting something similar to the gaping wounds in Dark Knight's Harvey Dent. The ears are almost non-existent, but the eyes are unobscured, allowing Jackie to emote effectively. In fact, the whole look, while horrifying in one context, is also, in another sense, rather sympathetic and wholly real. We can imagine that it will allow an actor such as Jackie Earl Haley a greater range of emotion, depending upon his portrayal."
