Collagen is one of the most researched proteins in skin health, but what does it actually do and why should we care? Here’s our guide to understanding collagen and its role in healthy skin.
What is collagen?
Collagen is the most abundant protein in the human body and one of the major building blocks of bone, skin, tendons, muscles and ligaments
What does collagen do?
Collagen's main role is to provide essential structure, strength, and elasticity to skin, bones, tendons, ligaments, and cartilage.
What are the different types of collagen?
There are over 29 different types of collagen, with each type being based on its individual amino acid composition. However, types I, II and III are the most common types of collagen found within the human body.
Type I
Accounts for 90% of the body’s collagen with its role being to provide structure to bone, skin, tendons, cartilage and connective tissue. It is most dominant within connective tissues.
Type II
Primarily found in cartilage, which helps to cushion the joints, and is important for supporting a healthy skeletal system.

What is a collagen supplement?
Supporting your skin from within can make all the difference. One way to do this is using a collagen supplement, either in capsule or powder. Collagen supplements promote healthy skin renewal and help strengthen connective tissue, helping you maintain a smoother, stronger complexion all year long.
Do I need to supplement collagen?
Whilst you can get collagen naturally from your diet, taking a supplement is a great way to confidently ensure collagen is in your diet, and counteract the natural decline of collagen production that occurs with age.
There are many factors that can can all accelerate collagen breakdown, such as genetics, inflammation, UV exposure, pollution, lifestyle habits and diet. For example, for those thinking about their skin health during perimenopause, a collagen supplement may offer extra support, as hormonal changes at this stage of life can impact the skin’s natural collagen levels
In 2022, a review of human clinical studies investigated *“Collagen Supplements for Aging and Wrinkles: A Paradigm Shift in the Fields of Dermatology and Cosmetics.” The review found that oral collagen supplementation was associated with improvements in skin hydration and elasticity, with some studies also reporting reductions in skin roughness and wrinkling.
