Richard does have a good point, though !!!
Esp. being on the tip of the nose, sometimes they DO rub and cause a blister that will then dry up and look like old shed.
I would have a go at it with a moist towel, but do not exert to much pressure. If that piece doesn't get soft and is easily pulled off...let it be.
Have you ever seen the snake nose around, push and try to escape?
