Collagen peptides: Support your skin the nutritional way

Registration is now open for Rousselot's webinar

New information is emerging and it’s changing our understanding of skin beauty. Consumers are becoming more aware of the scientific studies that support new innovations in the skin care industry.

The concept ‘beauty from within’ is finding its way into the consumer’s mind.

‘Beauty from within’ is the idea that skin beauty should also be addressed by daily nutrition. The part of the industry that focuses on this area is known as ‘nutricosmetics’.

To the Asian skin care consumer the idea of ‘beauty from within’ isn’t a new one. Asian culture has been leading the way in this area for decades. The rest of the world, however, is fast catching up, with a growing number of people around the globe discovering the value that nutricosmetics has to offer.

So what exactly is ‘beauty from within’?

When it comes to skin beauty, the consumer’s mind is still caught on the idea that ‘if the problem is the skin then the solution should be applied directly to the skin’.

Yet, in light of today’s growing scientific knowledge and developments, this isn’t the only approach.

The human body is amazing. It absorbs micro- and macronutrients, breaks them down and uses them as building blocks to synthesise the nutrients that contribute to a healthy body. So ‘beauty from within’ is about giving the body the necessary nutrients with which to repair and regenerate skin, hair and nails.

Let’s take vitamin C as an example. If your body doesn’t get enough vitamin C, you may start to get indications such as skin problems. You could apply creams and lotions to help you manage the symptoms. But the best way to solve the problem is to treat the underlying cause, which is the vitamin C deficiency.

Similar logic can be applied to skin beauty: if you follow a healthy and balanced diet that includes the right amount of nutrients, you may give your body the best chance of regenerating and strengthening the skin. That is the very essence of ‘beauty from within’.

How skin beauty is affected by the ageing process

The skin aging process is complex. It’s the result of a combination of environmental and physiological factors. Being exposed to the elements takes its toll on our skin, causing a breakdown of collagen, a structural protein of utmost importance to skin beauty.

It defines and assures the strength, elasticity and firmness of the skin. The body produces less collagen as we age, which means the body is less able to repair the environmental damage. This is one of the reasons why our skin starts to develop lines, wrinkles and blemishes and eventually can become saggy.

It isn’t just about collagen either. Part of the skin ageing process is due to dehydration. There is an important molecule, hyaluronic acid, that helps to keep the skin well-hydrated, which is essential for keeping our skin healthy and good-looking.

The amount of hyaluronic acid in the skin decreases as we age and this reduction in skin hydration contributes to some of the changes associated with older skin.

So if part of the skin aging process is the result of the body’s own regeneration capacities slowing down, then it makes sense to look for ways to stimulate the body into producing more of the necessary components that preserve skin beauty.

And there is good news on that front: a growing body of clinical evidence demonstrates that a daily intake of collagen peptides can stimulate collagen and hyaluronic acid production in the body, which leads to improved skin properties such as elasticity and smoothness, as well as an increase in skin hydration1.

On top of all these skin benefits, the science also suggests that collagen peptides may improve hair strength2.
