The Lizarderm skin lotion.
Lizarderm is a fictional skin lotion with its own advertisement presented by Reptile, whose scaly reptilian skin can be made as smooth as a baby gator's bottom with the lotion's help, as the ad claims, and the picture of it is found in the koffin BU, within the Krypt and the Extras kontent gallery of Mortal Kombat: Deadly Alliance.

"If you’re like Reptile, you’ll shed an entire layer of scaly skin every season. Just because you’re an evil acid-spitting lizard doesn’t mean you can’t have that smooth, shower fresh skin you’ve always wanted. With Lizarderm, you’ll be soft as a baby gator’s bottom."
