Scientific evidence proves the moisturizing and anti-aging effects of Peptan™ on skin.

Courbevoie, 5^th May 2009 – Many products with beauty claims already exist but consumers are not always confident about the validity of manufacturers’ allegations and expect valid scientific studies as proof of the claims. In the same way, hydrolyzed collagens in general have long been thought to be beneficial for skin health.

Over the last few years, Rousselot has developed unique qualities and grades of hydrolyzed collagens that are sold and consumed throughout the world under the Peptan^TM brand.

To assess the efficacy and acceptability of Peptan^TM, Rousselot has commissioned two double-blind randomized clinical studies versus placebo in France and in Japan. The objective was to definitively provide nutricosmetic manufacturers as well as end consumers with reliable and accurate measurements of the benefits of Peptan^TM Hydrolyzed Collagen for skin.

In France, 47 European women aged 35 to 55 were selected by DERMSCAN, to participate in a study over a 12-week period in winter. At the same time in Japan, 33 Asian women aged 40 to 59 were select by SOUKEN, for a period of 8 weeks.

In both studies, women ingested 10g of Peptan^TM Hydrolyzed Collagen every day, and their skin conditions were assessed by dermophysiological measures and self-assessment questionnaire.

The first evaluation of Peptan^TM was for its moisturizing effect. Measurements demonstrated a 28 % improvement in the skin hydration level in the Peptan™ group compared with the placebo group. 91 % of Peptan volunteers skin hydration level increased after an 8-week test.

The second evaluation of Peptan^TM was for its anti-aging effect. The number of micro-relief furrows decreased by 26 % compared with the placebo group. The number of deep wrinkles increased by 30 % with the placebo group while remaining stable within the Peptan^® Group after a 12-week test.

Researchers conclude that when taken daily for up to 12 weeks, Peptan^TM Hydrolyzed Collagen improves the basic condition and structure of skin: Peptan^® has been clinically shown to improve skin moisture level, skin suppleness and skin smoothness by reducing the number of micro-relief furrows and prevent the formation of deep-wrinkles.

With the population tending to be increasingly conscious of the importance of good skin health, Peptan^™ Hydrolyzed Collagen is indisputably a highly potent ingredient for the nutricosmetic market.

Rousselot looks forward to receiving visitors at stand 348 where they will receive full details of its clinical studies, origins and grades of Peptan® used and additional statistics.
