The wrinkles and skin folds you are referring to sound like dehydration. You may want to try giving the snake a 15 minute soak in luke-warm water and make sure there is a bowl of fresh water in the enclosure at all times.

To get any more specific about whether the environment needs to be adjusted, we'd need specific info from you.

1. What size/type of enclosure? (glass tank, tub, display enclosure)
2. How are you providing heat? (heat lamp, UTH, CHE, radiant heat)
3. How are you MEASURING the heat? (Digital thermometer, analog - dial type, temp gun?
4. How are you REGULATING that heat? (T-stat, rheostat, dimmer)
5. What kind of substrate (bedding) are you using?

Also, as a general rule of thumb, when you bring a new snake home from the store, reptile show, or wherever you got it, you want to put it in the enclosure and leave it alone to adjust. This means no handling the snake (except to clean and change water if/when needed) for a minimum of 1-2 weeks, but generally speaking, until the snake is eating regularly...

Good luck with the little guy... Pics of the snake and the enclosure would greatly help us to help you...
