Why doesn't Deadpool's healing ability heal his skin?
In the Deadpool movie when Wade his mutant cells get activated, his skin changes so he looks like Freddy Krueger (As Weasel referred too). But he obtains healing abilities and his cancer gets cured because of it. He's become an immortal person which can heal any wound super fast.
What I don't understand is, why doesn't his skin heal so he would look like before? I remember that Francis (or Ajax) said that it's a 'side-effect' of mutating, but why wouldn't it heal when he has a healing ability?
Best Answer
Its the same as his comics counterpart:
After the healing factor was given to him, it made his normal cells as well as his cancerous cells unable to die, giving him a heavily scarred appearance beneath his suit. - Wikipedia
So these cancerous cells made his weird appearance and his healing factor assumed it was part of himself and keep it in the same manner.

Answer 2
Deadpool is not cured of his cancer. When he gets his healing factor, so does his cancer, becoming super cancer. His healing factor fights it at an accelerated rate, but neither wins. Hence his face. And anti-telepathic brain. And insanity.
The cancer is just mutations in normal cells. Wade is genetically predisposed to it, so the healing factor can't stop it from happening. And since the cancer has his DNA, it has the new healing factor too. He can't just cut out the cancer, as new cancer cells spontaneously mutate everywhere.
His skin, like all his other internal organs, including his brain, constantly get cancer, which the healing factor fights off before they can become fatal. It changes how his skin looks often, and how his brain is wired. Since his brain isn't normal, and constantly changes, it causes him to be immune to telepaths.
His cancer wasn't cured. It was deadlocked in a never ending battle. Somewhere in Volume 2 of Deadpool comics, Daniel the hack Way wrote that removing the cancer without removing the healing factor will lead to the healing factor overcompensating and killing Deadpool, as it did the Super-Skrulls that were given his healing factor.
Answer 3
The answer was actually provided in the scene. Essentially, his cancer is growing rapidly, but his healing ability prevents it from growing out of control. It's in a state of balance, if you will, between the cancer growing and his healing fixing it.
Answer 4
Think of it this way, the healing factor fixes what's wrong when it takes full effect. Wolverine grows to adult hood, healing factor takes full effect, wolverines can heal any wound quickly, but eventually dies off of old age. Wilsons healing factor didn't finish maturating until the cancer cells had riddled his body, so the healing factor "thinks" they belong there, and fixes every cell. It's not magic like in Kim Harrison's the Hallows novels where the magic replaces the exact body the dna blueprints. (Loss of scars, ageing, and hair removal.) so healing factor heals what is there, magic heals to what should be.
