Skinfolds by neck

Gotta little question.

Every once in a while my 8 year old BP that is about 4 feet get a skinfold about an inch long right bleow his jaw on the side.

He is pretty healthy and bulky. Eats well and the tank environment is good.

It goes away and comes back from time to time.

Is this a big deal?

Does it come and go when he sheds or just random times?

If it is timed with the sheds you might want to bump the humidity up during the shed period, but as long as the skin all comes off in one piece then you should be good to go.
