"Foreskin on the Forehead: The Latest in Beauty"

A fellow named Buck Wolf posted that headline and the following article on Friday. Turns out the Brits have found at least one good use for the otherwise disgusting foreskin -- grind it up and use it in skin treatments. The product is called Vavelta (not to be confused with Velveeta, the cheese product that foreskins and smegma might remind you of), and it apparently really helps damaged skin. So instead of discarding those ugly little pieces of foreskin, let's recycle them to help our ladies!

"If you find the idea of taking Botox injections disgusting, why not try a little foreskin on the forehead? Scientific American is reporting that 150 patients in Britain have received injections of Vavelta, a skin treatment derived from the discarded foreskins of babies intended to rejuvenate damaged skin, including wrinkles, acne, burns and surgical incisions.

"It seems that Vavelta is brimming with fibrobrasts, a skin firming protein that becomes scarce with age. The treatment is approved in the U.K., but the F.D.A. has yet to approve the drug.
Of course, many boys have been circumcised for generations, and no one seems to ask where the foreskins end up. Some, we now now, end up on women's faces. But if you support stem cell research (and I do), how can you oppose this?"

Good Use for the Worthless Foreskin

The disease-entrapping foreskin can cause real harm to the male and his partners -- but researchers have known for years that detached from the human penis the foreskin may have some good uses. The most important one, it seems to me, is to help burn victims and others who need skin grafts. When we achieve 100% circumcision rates, we will increase the supply of foreskins for this important function. Here's an excerpt from a recent article that cites work at Wake Forest, suggesting that skin grafts from foreskins may be better than regular skin grafts. Now this is a good use for the otherwise worthless foreskin.

"At present, skin grafts can be expanded by making cuts in them to create a mesh, or by inserting balloons under the graft once it has been attached to the body.

"These gradually expand, stretching the overlying skin. But, skin meshes heal unevenly and balloons are painful, take months to expand fully and leave scars.

"According to a report in New Scientist, to try to improve on this, Sang Jin Lee of the Wake Forest Institute for Regenerative Medicine in Winston-Salem, North Carolina, took foreskin donated after circumcision and placed it between vices inside a bioreactor, a vessel that bathes the skin in nutrients to encourage cell growth and division.

"The vices were controlled by a computer and could be set to move apart at specific times.
The researchers found that the best method was to stretch the skin at hourly intervals, leaving it to produce new cells in the meantime, then stretching it again.

"By doing this, they were able to elongate the skin by 20 per cent a day, which after five days resulted in an intact strip that was twice as long as the original.

"Tests of the stretched skin showed that its general structure was maintained and that its thickness and pore size were almost identical to the starting tissue.

"Lee said that they have since added extra vices to stretch skin lengthways and widthways at the same time."
