Hydrolysed collagen may boost beauty from within: Rousselot studies

Daily supplements of a hydrolysed collagen may improve skin hydration by 28 per cent, and reduce the wrinkles by 30 per cent, say two new studies from Rousselot.

The company presented the results at PalExpo in Geneva at Vitafoods, with skin suppleness also reported to increase by 19 per cent.

Speaking to NutraIngredients at Vitafoods, Caroline Negre, RHC Marketing Manager for Rousselot, said that the findings would be published in a peer-review journal before the end of the year. NutraIngredients.com has not seen the full data.

Negre confirmed that the company had received a lot of interest at the show for the ingredient. “Rousselot is very optimistic because there are only a few skin health ingredients with clinicals to support them,” she said.

The results tap into the 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'.

There is a growing body of science focusing on the potential benefits of nutrients to boost skin health from within, with lutein, lycopene, flavanol-rich chocolate, and superoxide dismutase (SOD) having been reported to improve skin health.

Study details

Using the company’s Peptan hydrolysed collagen, researches in France and Japan performed two double-blind, placebo-controlled, randomised clinical studies. The French study involved 47 European women aged between 35 and 55, while the Japanese study involved 33 Asian women aged between 40 and 59.

The European study lasted for 12 weeks in winter, while the Japenese study occureed at the same time and lasted for 8 weeks. In both studies, women ingested 10g of Peptan hydrolysed collagen every day, and their skin conditions were assessed by dermophysiological measures and self-assessment questionnaire.

According to the company, women receiving the collagen supplement experienced a 28 per cent improvement in the skin hydration levels, compared to placebo, with 91 per cent of these women reporting increased skin hydration levels after eight weeks.

Furthermore, the number of micro-relief furrows and deep wrinkles decreased by 26 and 30 per cent, compared with the placebo group, said the company

The company confirmed that the peptan ingredient is available in powder form.
