MEDICINE, Page 85Want a Shot of Sunshine?
A new drug can tan the skin indoors, but don't throw out the
In the 70 years since Coco Chanel's bronzed mannequins helped
make the perfect tan a symbol of leisure and affluence, a
well-browned body seems to have joined the pantheon of
inalienable human entitlements, right there alongside life,
liberty and the pursuit of good TV reception. How else to
explain the fuss made last week in the prestigious Journal of
the American Medical Association about the newest way to achieve
that sun-kissed look: by injection.
In a seven-page report, with accom panying editorial, a
team of scientists led by University of Arizona dermatologist
Norman Levine told how, in a randomized, placebo-controlled
experiment, visible tanning was induced in 15 healthy men after
10 injections of a potent hormone called MSH
(melanocyte-stimulating hormone). The tans lasted nearly nine
weeks with no immediate side effects beyond a brief flushing
sensation and a mild stomachache.
But it's hard to imagine sun worshipers lining up at
doctors' offices for their bimonthly tanning fix. No one should
take any hormone without considering the long-term
consequences. And as the J.A.M.A. editorial points out, MSH is
a powerful brain chemical associated with a wide range of
neurological effects; it is known to influence verbal memory in
humans and sexual behavior in rats. Levine and his colleagues
argue that tanning shots might offer protection for fair-skinned
patients who sunburn easily, a group increasingly at risk for
skin cancer as the ozone layer shrinks. But is that anything
that can't be achieved at lower cost and less danger with a
smear of sunscreen and a wide-brimmed hat?
