Components of Cocoa Enhance Skin Appearance
Now, new research just published in the Journal of Nutrition reveals
the potential benefits of consuming flavanol-rich cocoa and how it
might actually benefit skin from the inside out.
Researchers found that certain components in cocoa may actually help
improve the appearance of women's skin - increasing hydration,
decreasing skin roughness and scaling, and helping to support the
skin's defense against UV damage. The German scientists attributed the
observed benefits to cocoa flavanols - a group of compounds that can be
particularly rich in cocoa and that have been previously reported to
improve blood flow and vessel function.
In this new study, 24 healthy women (aged 18 to 65) were randomly
assigned to two groups. One group drank a high-flavanol CocoaproŽ cocoa
beverage (329 mg) once a day, while the other group consumed a matched
cocoa beverage low in flavanols (27 mg). At three different periods
during the 12-week study, various tests were conducted to evaluate skin
properties: sensitivity to UV irradiation, skin blood flow, skin
structure and texture, and skin hydration.
The women who regularly consumed the high-flavanol cocoa beverage
showed significant improvements in these indicators of skin quality,
while those who consumed the flavanol-poor cocoa did not have an
improvement in any of the measures.
"We are excited by the extent of improvements to the skin," said
Catherine Kwik-Uribe, PhD, senior research scientist at Mars,
Incorporated, which has supported and conducted much of the research on
cocoa flavanol health, including this new study. "Much of the interest
in skin health has focused on what you put on the skin. From our
extensive research on cocoa flavanols over the last several years
demonstrating their potential positive benefits on circulation, it is
rewarding to see that these benefits may extend to skin quality as
well."
In addition to the improvements in skin quality in study
participants, this study is the first to suggest that the regular
consumption of cocoa flavanols may support human skin's defense against
UV light. Study participants exhibited a reduction in the redness of
skin following exposure to artificial sunlight. The authors of the
study believe the skin benefits of cocoa flavanols may be due in part
to an improvement in blood flow to the skin. Consistent with previous
studies that demonstrated significant improvements in vessel function,
in this study, the regular consumption of flavanol-rich cocoa resulted
in a significant increase in blood flow to the skin's surface, effects
that were sustained with the regular consumption of cocoa flavanols
