Since the Joker's apparent death in the bat cave, his body happened upon a pool of the substance dionesium which healed wounds and revived the dead. Within the pit, Joker grew a new face which he would go on to use during his endgame.
The Joker has had various possible origin stories during his decades of appearances. The most common story involves him falling into a tank of chemical waste that bleaches his skin white and turns his hair green and lips bright red; the resulting disfigurement drives him insane.
Shortly after this, Joker told Batman that he knows who everyone is in the Batfamily and that he had grown bored with their “relationship". Cutting off his face was to show that he was indeed and had indeed fallen to even greater depths in his insanity and that he was moving on to the endgame.
Jerome lives on Gotham, but only after stapling his own face back to his head. In a new “white band” trailer for Gotham, Jerome's return as the Joker (or at least Joker-like villain), we see Jerome return to the city with his old face and Bruce Wayne as his hostage.
According to the Joker, his wife (who often mentioned that he needed to "smile more") found herself in trouble with gambling sharks who "carved her face." As the pair couldn't afford surgery, and in an effort to reassure his wife that he didn't care about her scars, the Joker disfigured himself in solidarity.

Batman reappears and engages the Joker a second time in a far more violent fight, in which the Joker hysterically stabs him in the stomach several times. Mid-stab, Batman instinctively breaks the Joker's neck just enough to paralyze him. Joker laughing his last laugh while he snaps his own neck.
According to the 2017 documentary I Am Heath Ledger, the actor's prosthetic scars, which were caked in red paint, kept coming loose on set. Ledger's habitual licking began as a reflex to check the scars were still in place and to ensure they stayed in position.
It is at that moment The Joker springs to life, killing two of Gambol's men before sticking a knife in Gambol's mouth. He proceeds to tell the gangster that he got his Glasgow smile (cheeks slit from the lips) from his deranged, drunk father.

He's a creepy nightmare that even the Joker is afraid of. And for good reason, since the Batman Who Laughs is basically the skill and tenacity of Batman mixed with the chaotic evil of the Joker. In Justice League #13 that character is a major talking point between Lex Luthor and the Joker.
Dick Grayson, the original Robin, gets word that Batman snapped and killed the Joker. He goes back to Gotham to confirm this, and sees the body himself. It's just a mangled corpse out of view, but fans know the green hair anywhere.
The actor, 44, agreed to lose 52 lbs. at the urging of director Todd Phillips, who thought his character, Arthur Fleck, should be “real thin.” Phoenix lost the weight carefully, under the guidance of a doctor, but the strict calorie deprivation he endured affected his eating habits well after he hit his goal.
