It's Criss Angel!

We got clean cut Criss Monday night at his charity event in Vegas, where he lost the eyeliner ... and his long locks. 

The event was for pediatric cancer research -- his toddler son, Johnny, was diagnosed with the disease last fall.

Johnny was front and center with dad ... in high spirits.
