How do I get wrinkles out of a Don Post mask?

Hi there. I’m new here and this is my first post. I recently bout a Don Post 2005 mask, but it is badly wrinkled and therefore it does not look like Michael Myers at all. I have tried using a Hair Dryer and even using my regular dryer, but to no avail. I need some serious help and I don’t have the money to buy another mask. I also don’t want to wait until next year to by my favorite horror movie villian. PLEASE HELP!

I have never seen anyone post about a mask having wrinkles…
Can you post a picture? I’m curious to see where the wrinkles are?
You should buy a mask display stirofoam head and let the mask smooth out with time?
if not…maybe painting the mask…kinda complicated but half liquid latex (NOT to be confused with FLESH latex) and half acrylic paint might fill on the wrinkles. Best of luck to ya! PM me with any questions.
