R&D for Lifetime of Life

Chocolate, aging, wrinkles etc.

There’s an old story which suddenly has a new lease of life in the newpapers. “Studies have shown that just 20g a day of the chocolate could help prevent wrinkles by hydrating the skin and improving elasticity.”

Hydrating the skin? Improving elasticity? The wonder chocolate is Acticoa, which goes into a large number of well-known brands.

The trigger for the second round seems to be that lead researcher Dr Stefanie Williams posted the story as news on her blog 2 days ago.

The original round began in Sep 2009 with the publication of a study in the Journal of Cosmetic Dermatology.  Volunteers were asked to eat 20g of chocolate/day for 12 weeks, one group getting high in flavonols, the other low in flavonols.

At the end it was found that the mnimum dose of UV-B required to cause redness had roughly doubled in the high flavonol group, with little change in the other group.

The report concluded that chocolate high in flavonols “can thus be effective at protecting human skin from harmful UV effects”. The link to Acticoa seems to have come out later.

NHS Choices was critical of potential problems with the study – click here for the issues.

On its website, Acticoa lists a large number of studies on chocolate, but not this one.
