[DC Films] Why did Joaquin Phoenix's Joker's makeup seem to stay on much better than Heath Ledger's Joker's makeup?

Ledger's Joker's makeup seemed to keep peeling off, yet Phoenix's Joker's makeup didn't seem to have that issue. Why not?

In Joker, he is, by trade, a clown.  Makeup (both quality, and application) is a professional requirement for the job and one he would have paid close attention to for that reason.

Ledger's Joker on the other hand, has no clown-based origin that we know of so the makeup could very easily be of lesser quality or not applied properly, and with no care to the craft other than just to disguse and conceal.  That said, it also makes him look way more creepy and frightful.
