From their site- "If you are a new visitor and not familiar with what a reborn doll is, let us explain.
Reborn Dolls are becoming very popular and are highly collectible and at reborn-baby.com we specialise in this art.
The process of reborning a doll is being able to create as realistic baby as possible.
This is achieved by firstly buying or creating a doll mold to start the reborning process. Firstly the doll has to be stripped back to just the mold, any factory paint or accessories are removed. It is then necessary to begin coloring the dolls head, body and limbs through a variety of different techniques to give a very realistic human skin effect. This takes multiple layers of different paints to create mottled effects such as that of a newborn baby. We also often add veins which look like the type just under a baby's skin."
