Does PMMA need to be refilled or is it permanent?
Permanent but some with extreme dysmorphia go back for refills, if the doctor is willing to indulge.
It's actually good that it's permanent or the skin would be sagging after it depleted.
I guess, but it can shift around and even mess with nerve pathways I think.
