NEW CLINICAL STUDY CONFIRMS PEPTAN EFFICACY FOR SKIN BEAUTY AND HAIR STRENGTH
Rousselot, a Darling Ingredients global company and the leading global producer of gelatin and collagen peptides, has released the findings of a new clinical study on the effects of Peptan® collagen peptides on skin beauty and hair strength. Adding further evidence to Peptan’s strong scientific portfolio, the study revealed that the oral supplementation with Peptan collagen peptides significantly contributes to improving the overall appearance of skin and hair in an ethnically diverse population.
Promoting smooth-looking skin with collagen peptides
The randomized, double-blind, placebo-controlled clinical research was conducted with 60 healthy Brazilian women, aged 45 to 60 years. During a set period of 90 days, a group of 30 participants received a 5g daily dose of Peptan collagen peptides from bovine origin (Peptan B) while the remaining subjects consumed a placebo control. Parameters of skin characteristics in the region of the cheeks, around the nose, eyes, mouth, as well as hair strength, were evaluated at baseline prior to supplementation and again 45 and 90 days after supplementation with high-end, state-of-the-art techniques.
Results showed significant improvements in the overall appearance of the skin, characterized by a decrease in periorbital wrinkles by 13% and nasolabial wrinkles by 10% and a reduction of the visibility of pores in the region of the cheekbones in 57% of the Peptan-supplemented participants. At the basis of those observations was a clear increase of the density of the dermis, which contains the strength-providing collagen layer of the skin, following Peptan supplementation.
Bringing new scientific evidence for hair strength
While collagen is known for promoting stronger and healthier hair, there has been no scientific assessment of these beauty benefits until now. This new study evaluated the characteristics of hair using a texturometer before and after Peptan supplementation clearly demonstrating an increase of the mechanical strength of the hair by 13% in the Peptan group compared to the placebo group. Mechanical strength is linked to improved properties of the hair cortex, which can be especially beneficial for aging hair.
Broadening Peptan’s Scientific Portfolio for Skin Beauty
The new scientific evidence broadens the understanding of benefits delivered by Peptan collagen peptide supplementation for beauty in several ways. Previous clinical reports have demonstrated that oral Peptan collagen peptide supplements can reduce the signs of skin aging by improving skin hydration,,,, elasticity3,4,5 and dermal collagen density. The study provides further evidence on the efficacy of Peptan collagen peptides from bovine origin, at a lower dose. Conducted in a Brazilian population of mixed skin and hair types, this also brings additional proof that Peptan is efficacious across populations of different ethnical backgrounds2,5,,, adding to the previous evidence obtained from trials in Caucasian and Asian populations.
Peptan’s range of collagen peptides are safe, bioactive and developed through an optimized hydrolyzation process, which makes collagen peptides highly bioavailable, and provide targeted benefits in the key connective tissues of the human body. A leading global brand of choice, Peptan collagen peptides are widely used in nutricosmetic applications and continue to grow in popularity among manufacturers looking to differentiate their products, thanks to the wealth of vital information supplied by Rousselot’s extensive scientific research.

WHAT’S THE DIFFERENCE BETWEEN COLLAGEN PEPTIDES AND HYDROLYZED COLLAGEN?
COLLAGEN PEPTIDES OR HYDROLYZED COLLAGEN? IN THIS ARTICLE WE CLARIFY THE TWO NAMES AND GET TO THE ROOT OF WHERE THEY COME FROM AND WHAT THEY MEAN.
There is no difference. The terms collagen peptides and hydrolyzed collagen are synonymous and used interchangeably for the same product. It’s just a matter of semantics. The phrase ‘collagen peptides’ is based on the end product, which are peptides derived from collagen; whereas ‘hydrolyzed collagen’ comes from the hydrolyzation process, the method by which collagen peptides are made.
For a simple illustration, consider the ingredient ‘wheat flour’. You can call it ‘ground wheat’, after the grinding process. Or ‘wheat flour’ after the end product i.e. flour.
So hydrolyzed collagen is just another way of saying collagen peptides.
Hydrolyzed Collagen vs Collagen Peptides: Which phrase to use?
Either one. They’re both legitimate. Though in recent years there has been a trend towards using the name ‘collagen peptides’. This is because the peptides derived from collagen are the key bioactive component; in other words, it’s the bioactive peptides that add value to a wide range of nutritional and nutraceutical products, so it makes sense to use ‘collagen peptides’.
What is collagen?
Collagen is an important structural protein found in animals. Essentially it holds the body together, giving strength, structure, elasticity and cohesion to bones, skin, muscles, tendons, ligaments and cartilage.
There are different types of collagen in the body. Collagen Type I, for example, is made up of very long, tightly packed fibers that give tensile strength to ligaments, tendons and skin. The fibers in Collagen Type II, on the other hand, are shorter thereby allowing cartilage to absorb shock between bones and to cushion joints. So it’s an essential substance for maintaining good physical health.
As we grow older the body produces less collagen, which results in visible signs of aging such as lines and wrinkles. This is because there is less collagen providing elasticity and structural support to the skin.
Collagen (typically skin and bone from fish, porcine and bovine) is the raw material from which products such as gelatin and collagen peptides are made.
What are collagen peptides and what is the collagen hydrolyzation process?
Collagen peptides are short chains of amino acids extracted from native (full-length) collagen via a process called enzymatic hydrolysis (also enzymatic hydrolyzation).
So the native collagen (e.g. bovine hide) has to go through a softening process that allows the collagen peptides to be released from their bonds and safely extracted. At a molecular level collagen is made up of three long amino acid chains that form a triple helix with a high molecular weight. As a result, collagen peptides are part of a tough and insoluble matrix of collagen fibers.
The collagen then goes through a process called enzymatic hydrolysis. This is where a specific enzyme is used to break down the peptide bonds so the collagen peptides can be extracted. The degree of hydrolysis has an impact on the average molecular weight of the final product.
The process of enzymatic hydrolysis is strictly controlled to ensure reproducibility.
Why are collagen peptides (hydrolyzed collagen) beneficial?
Collagen peptides are bioactive. That means, once absorbed into the bloodstream, they can influence the activity of cells in the body in multiple ways. For example, collagen peptides can stimulate fibroblasts in the skin to make more hyaluronic acid, which is essential for skin hydration.
Bioactive collagen peptides can help the body repair damaged tissue. It can provide structural support for skin, contribute to healthy hair, and help maintain bone density. This is why collagen peptides are used for a range of health, beauty and fitness needs.
For example, various scientific studies have shown that collagen peptides can help improve joint health1,2 by protecting cartilage from degradation and helping to reduce inflammation around the joint. This has beneficial effects for people with joint conditions as it can help improve mobility and reduce pain.
Other uses for collagen peptides:
Collagen peptides are used by athletes, bodybuilders and sports enthusiasts to help reduce their recovery time following intensive training. Strenuous activity puts a strain on muscle fibers and the wrapping sheath of connective tissues, so the body needs time to heal before doing more training.
Collagen peptides can support recovery by reducing the recovery time, meaning sports-people can maximize their training schedule and improve performance.
As well as faster recovery times, taking collagen peptides can also reduce muscle soreness.
Collagen peptides can support bone health. Bones are predominantly composed of collagen and calcium salts. Throughout a person’s life, bones are constantly repairing and regenerating in a process known as bone remodeling.
As a health supplement, collagen peptides can be used to boost the bone remodeling process and help maintain good bone health. In a recent pioneering study4, researchers found that collagen peptide supplementation can influence the metabolism of bone cells at multiple levels promoting the remodeling process and helping the body maintain the strength of its bones.
Collagen peptides are used to help improve skin health and slow down the visible signs of aging such as wrinkles. There have been several scientific studies that demonstrate collagen peptides’ ability to aid skin beauty. In 2015, the results of two clinical studies4 showed that collagen supplementation improved the appearance and hydration of skin for Caucasian and Japanese women respectively. Another study5 from 2019 confirmed that collagen peptide supplementation has positive effects on the skin in participants of varying skin types.
