In the treatment, developed by Isolagen of Houston, Texas, skin cells from the back of the ear are grown in the lab for about eight weeks, and then injected beneath frown lines and scars by a plastic surgeon.
Isolagen claims that the implanted cells grow in the same way as ordinary skin cells and that, unlike collagen fillers or the nerve-paralysing toxin Botox, the effect does not wear off. In fact, it claims, the effects get better over time. If so, it may be the closest anyone has come to achieving true skin regeneration.
