Wrinkle Cure From Vitamins?

Applying anti-oxidant vitamins
directly to the skin can slow the formation of new wrinkles and
erase, to some extent, existing wrinkles and lines, according to
a study made public on Thursday.
The study by a non-profit independent group of French
scientists found that applying vitamins C, E and beta carotene
to the skin may significantly reduce the long-term damage caused
by ultra-violet radiation, a key component of sunlight.
It may also actually partially reverse damage already done,
the scientists said.
Exposure to the ultraviolet radiation in sunlight is a key
cause of skin ``aging.''
``We have found that topical anti-oxidants can benefit the
skin significantly and play a protective role,'' said Dr Serge
Hercberg, the study's coordinator, in a statement.
``Our final results determined that regular application of
anti-oxidant vitamins to the skin not only inhibits
ultraviolet-induced damage...but may also facilitate the repair
of existing damage -- the result of which is loss of elasticity
which could lead to wrinkling and premature skin ageing,'' he
said.
The research group's work is supported by grants from
private firms in various industries.
U.S. cosmetics firm Estee Lauder provided the anti-oxidant
vitamin product used in the trial and participated in the study,
a spokesman for the project said.
The findings are due to be presented to international
dermatology meetings next month, the spokesman told Reuters.
The study, part of a larger eight-year study of nutrition
and health in Europe, looked at 160 French women over an
18-month period.
Researchers divided the women into four groups. One took the
vitamins in the form of pills, and a second rubbed the vitamins
directly on the skin.
The remaining two groups either ingested or applied placebos
-- harmless compounds containing no vitamins -- solely for
comparison purposes.
``The most profound results, obtained after 18 months of
treatment, clearly showed a marked improvement in the condition
of the skin,'' the researchers' statement said.
They found ``a 23 percent reduction in the formation of new
lines and wrinkles and an eight percent reduction in existing
lines and wrinkles.''
Much is already known about the ability of anti-oxidant
vitamins to protect against the damaging effects of free
radicals, a highly reactive type of oxygen atom that occurs
naturally in the body and can harm tissue, constrict blood
vessels and stimulate cancer growth.
The researchers said their study was the first to focus on
the vitamins' effect when applied to the skin rather than
ingested.
The larger study, known as the Supplemental Vitamin and
Mineral Antioxidant Trial, or SU.VI.MAX, began in 1993 and
involves some 15,000 subjects.
It is the largest trial of its type on nutrition in Europe.
