It sounds like just another uber-meltable cheese product, but Vavelta is actually miles away from anything you'd want to put in your mouth. It's a radical new treatment for facial pitting, scarring, and wrinkles made out of—what else?—newborns' foreskins. Foreskins have long been treasured by cosmetic dermatologists because they are rich in fibroblasts, tiny cells that play a crucial role in healing wounds and generating collagen and connective tissue. (One foreskin can be bioengineered into a piece of lab-grown skin the size of a football field.) The makers of Vavelta extract them by finely dicing the foreskins and treating them with enzymes. Then the fibroblasts are suspended in a proprietary cell storage medium and injected into "problem areas" with a fine gauge needle.
