Facial Horror

Much like audiences get squicked out by horrible things happening to our body or our eyes, so too do they get absolutely sickened by the thought of something horrible (and permanent!) happening to our faces. It's the #1 part of the body we use for socializing, so in essence, destroying a person's face is the equivalent to destroying his or her life. It can often lead to a Nightmare Face, but if the victim is lucky, he can maybe at least achieve the level of the Woobie or even Ugly Cute. This trope can include those who die from the disfigurement, but it's more effective (and more horrifying) to have the victim live with it.

Compare and contrast to Nightmare Face. The main difference between these two tropes is that Facial Horror deals specifically with severe mutilation of most or all of the face, whereas Nightmare Face covers exceptionally scary faces in general.

Anime and Manga

 * Hellsing invokes this trope several times, most of them involving Alucard. The worst is probably Zorin Blitz, who basically gets her face cheese-grated down a hallway by a supremely pissed-off and newly-awakened, leaving only ragged strips of skin. Towards the end  ends up suffering this trope when the Captain (nonlethally) shoots her through the mouth, giving her a Glasgow Grin and forcing her to wear bandages over it for the rest of her life.

Real Life
(WARNING: GOOGLE AT YOUR OWN RISK)
 * Jacqueline Saburido
 * Pakistani acid attack victim Fakhra Younus.
 * Charla Nash, before receiving a facial transplant.
 * Connie Culp, before becoming the first person in the U.S. to get a facial transplant.
 * Isabelle Dinoire was the first person to receive a partial face transplant after her own Lab mauled her. Looking up pre-operative images is rather horrific. Another warning, the very final paragraph of the whole incident also shouldn't be read by the squeamish. It describes what could happen if she stops taking her medicine.
 * Raymond Robinson, aka "The Green Man"
 * Emmett Till
 * James Vance, the real-life inspiration for the character Arseface of the comic series Preacher (Comic Book).
 * Michael Jackson: even die hard fans should admit that his never ending face lifts were absolutely horrible by the end.
 * Michael Jackson has nothing on Pete Burns.
 * Lai Thi Do, a 15 year-old Vietnamese girl, before she had a 12-pound facial tumor removed in 2008. There is a before picture in this news article. Click on it yourself, because linking it directly would force me to look at it again.
 * Ronald Poppo
 * Non-human example: Chase the cat, also known as Chase No Face, who was seriously disfigured in an accident at four weeks old. She has no eyelids, nose or upper lip as a result and requires medication every day to keep her eyes moist. In spite of this, she lives a happy life and is in no pain. In addition, she acts as a therapy cat for disfigured humans. Her (very heartwarming) blog can be found here.
 * Novemthree Siahaan, an Indonesian boy who had a rare condition that caused tumors to take over most of his face. The tumors were removed, but regrew and he sadly eventually died.
 * This poor, poor, poor, poor still living cat.
 * It's surprising that the team kept documenting this poor dying hyena (whose encounter with lions left its head looking like it has just been through a wood chipper), without putting it out of its misery.
 * The recently infamous case of a horrific bloody assault in Miami where a naked man named Rudy Eugene attempted to gnaw off the face (not bite, but GNAW) of a homeless victim named Ronald Poppo on a sunlit pedestrian ramp near a freeway. Even after the first shot, the drug-addled cannibal still continued to bite until he was finally killed by several more shots of gunfire, but not before leaving Poppo with his face ripped off, his eyes gouged, and his nose mauled, leaving only his goatee. You may kindly throw up now.
