Collagen has become something of a buzzword in the wellness and beauty industries over the last couple of years, so let's provide some clarity on whether collagen supplements, treatments and skincare products actually work!
What is Collagen?
Collagen accounts for one third of all proteins found in the human body, however, it is also the most abundant protein found in mammals. Collagen is part of the human extracellular matrix, which provides our cells with structure and support and works to regulate the physiology of our skin.
Essentially, collagen forms the fibrous connective tissue that gives the skin its structure, strength and elasticity and contributes to a fresh, youthful looking appearance. So, when we experience a loss of collagen in the skin, fine lines and wrinkles develop, and skin can become dry and thin.
If collagen is naturally occurring in the human body, why do collagen enriched products exist?
While it is true that collagen can be found in our skin, hair and nails, the body's natural collagen producing process naturally starts to slow down when we are in our twenties. Plus, the quality of the collagen that is being produced naturally starts to decline.
Additionally, there are a number of factors that can exacerbate collagen loss, including exposure to sunlight and environmental pollution, nutrient deficiencies, drinking alcohol and smoking.
What does older collagen look like?
It can be helpful to think of a collagen fibre as being like a piece of elastic. When elastic is used over a period of time, it tends to stretch and is eventually unable to return to its original form. Collagen fibres behave similarly, stretching out over time and losing their elasticity. This contributes to the development of fine lines and wrinkles and makes injuries to our tendons and joints more likely.
How can I increase collagen?
It is recommended to take collagen in the form of supplements or powdered collagen that can be added to smoothies, teas, and baked goods. Clinical studies have demonstrated that marine collagen supplements can positively impact skin elasticity, as they are more bioavailable than other forms, such as bovine collagen. Notably, studies have also shown that hydrolysed collagen or collagen peptides are easily absorbed by the GI tract, making this form of collagen more beneficial than other forms of ingestible collagen.
Vitamin C is a powerful antioxidant which can stimulate the production of collagen. In fact, our skin cells rely on vitamin C for collagen production as well as for support in regulating the overall balance of elastin and collagen.
Do collagen enriched skincare products work?
Yes. Collagen molecules are too large to permeate the epidermis layer of the skin. This is why the most effective anti-ageing skincare products contain ingredients such as hyaluronic acid and glycosaminoglycans, which are found within collagen molecules.
There are also a variety of other incredibly stable and safe aesthetic treatments that have been clinically proven to kick-start the body's own natural collagen production process, including polynucleotides, microneedling, chemical peels and radiofrequency to name a few.
