Grape seed boosts skin from within

A dietary supplement of oligomeric proanthocyanidins (OPC) could reduce reddening of the skin by 13 percent, scientists from Hamburg-based Bioskin GmbH have reported.

A dietary supplement of oligomeric proanthocyanidins (OPC) could reduce reddening of the skin by 13 percent, scientists from Hamburg-based Bioskin GmbH have reported.

Growing awareness of the link between diet and health, and by extension physical appearance, means that many consumers are receptive to the concept of 'beauty from within'.

The new research from Germany that links skin health to grape seed extracts could well be readily accepted by the female-dominated consumer base. The same Datamonitor report said that 63,7 percent of women over the age of 50 are prepared to spend more on cosmeceuticals.

The research study
The new study, published in the journal Skin Pharmacology and Physiology (Vol. 20, pp. 43-49, doi: 10.1159/000096171), looked at the effect of a OPC dietary supplement on skin reddening (erythema) induced by exposure to UV radiation.

Known as Masquelier's Original OPCs (oligomeric proanythocyanidins), Anthogenol, the Vitis vinifera seed extract is a rich source of antioxidants such as catechins and 2-5 flavan-3-ols.

Lead researcher, Betsy Hughes-Formella, and her colleagues from Bioskin recruited 42 subjects and randomly assigned them to one of two groups: group 1 received a daily Anthogenol supplement (100mg/day) and group 2 received no supplement.

After four weeks of supplementation, the subjects were exposed to UV radiation to induce erythema and then the subjects given topical OPC formulations in addition to the supplements.

13% less erythema
The researchers report that while the formulations did reduce skin reddening, the subjects receiving the dietary supplement of OPCs had 13 percent less erythema than those receiving no supplement.

Levels of skin hydration were also said to be higher in the group taking the dietary supplement.

“The regular use of Anthogenol products may help to protect from free-radical-mediated skin inflammation and to increase skin hydration,” concluded the researchers.

Growing body of science
The study adds to a growing body of science that has looked at the effects of dietary supplementation on skin health. Indeed, in recent months compounds ranging from lutein and lycopene to cocoa flavonoids have been reported to improve skin health.

The buzz about 'beauty-from-within' supplements has been increasing over the last few years, as evidenced by new ingredients in both the cosmetics and the supplements sectors and discussions at industry events. - (Decision News Media, October 2006)
