Kera-Diet® clinical study:
The effects of keratin hydrolysate on skin aging: an exclusive interview with Jean-Philippe Soulard
On the clinical study and its results
Can you tell us what prompted you to carry out this clinical study on Kera-Diet®?
We had previously carried out a clinical study on hair and nails at a daily dose of 1000 mg. Since then, we have regularly received questions from customers concerning the use of Kera-Diet® on the skin at a lower dose. A review of the literature in the light of previous results was a prelude to our latest clinical study.
What are the main results of the study, and why are they significant in the fight against skin ageing?
This is the first clinical study to show the positive effects of pure hydrolyzed keratin, with no other ingredients, on the signs of skin ageing. We were able to measure an average 10% reduction in wrinkles, as well as an improvement in skin firmness and elasticity.
On methodology and scientific rigor
The study was a double-blind, placebo-controlled study. Can you tell us more about the protocol and the reliability of the results?
In fact, the study participants did not know whether they were taking the dietary supplement containing Kera-Diet® or the placebo. This is a reliable, objective method of eliminating placebo bias and proving the efficacy of a treatment. The placebo group serves as a point of comparison.
Kera-Diet® implications and applications
How does Kera-Diet® differ from other anti-ageing food supplements on the market?
The anti-ageing dietary supplement market is vast and covers a wide range of applications. Kera-Diet® stands out for its effectiveness on skin, hair and nails (phanera) thanks to its high bioavailability. This keratin hydrolysate has the highest free amino acid content on the market.
On the future and scientific prospects
Do you plan to conduct further studies to investigate the effects of Kera-Diet® or explore new applications?
There are many applications for amino acids in the dietary supplements segment. In fact, there are several avenues worth exploring. One of the first steps is to gain a better understanding of how these amino acids act on cell ageing, which is the subject of a recent in vitro study.
Do you think nutricosmetics represents the future of anti-ageing skincare compared to traditional topical solutions, and if so, why?
It’s hard to make predictions. In any case, they complement each other in a number of applications, such as reducing the appearance of wrinkles. They act on different levels, with nutricosmetics providing nutrients and acting deep down to improve skin quality over the long term. Topical solutions have more targeted actions.
About BCF Life Sciences' commitment and vision
How does this study fit in with BCF Life Sciences’ innovation approach?
At BCF Life Sciences, we are constantly seeking to develop new ingredients and new applications. We do this by listening to the market and our customers, through scientific partnerships, and by taking part in conferences and trade fairs. Our customers also ask for products with a scientific underpinning and proven performance. This translates into studies (clinical, in vitro), scientific publications and patent applications. To achieve this, we allocate a significant proportion of our resources to R&D. It’s also a way of anticipating tomorrow’s issues.
