black marks on skin

[trevor]

Hi, one of my snails, he/she is about 5 years old, has got black marks around the base of it's eye stalks and the wrinkle of it's skin have smooth out/disappeared where the black is present. On one side the black mark moves down towards it's mouth. The marks look a little like burns or scalds that have healed up and turned black but there is no way the snails could have burnt itself.

I have quarantined it from the other 3 but I want to know if there is anything I can do to help it.
Can anyone help?

I can take some pictures if it helps.

Thanks
