Question About Mask Creases

Could anybody tell me if it’s possible to remove creases from a mask that hasn’t been properly cared for? If so, is there anyone who offers this service?

What I’ve heard is to stuff it and use a blowdryer. Then stuff it for a week or two.

If it’s an H1/H2 and it’s in the face area buy a Shatner lifecast/lifemask, you can use a blowdrier from the inside (could pose problems) or from the inside just massage in some EZ Strip (Home Depot has it) latex safe paint remover, then wipe it off with a damp paper towel or rag then pat it dry, it makes the latex slightly more malleable, then place the lifemask inside the face flush hold the creased area against it and hold it there face down with a dry microfiber cloth pressing against the creased area to have it flush to the lifecast’s surface, and hold it there for a while, check on it then go back to it if necessary.
If it’s in an area the lifecast won’t reach then you’ll have to use your hands to keep it in shape, though you could also try using some scotch tape from the inside to try and try to hold it in shape after using the blow drier or EZ Strip from the inside, then stuff the mask as well (polyester fiull is the best followed by plastic bags). The scotch tape residue would be minimal and would easily come off with some Goo Gone or the EZ Strip.

Thank you for all the advice! It is actually a Resurrection mask that I have always been meaning to get overhauled, but need to remove the creases first.
