Why Collagen is Important for Skin Health

Read our editorial policy to see how we create informative, accurate content.

What is Collagen?

Collagen is an essential protein acting as a primary component in the majority of the structures within our bodies. It holds the title as our body's most plentiful protein, accounting for approximately one third of the body's total protein. The 28 recognised types of collagen vary in prevalence, but Type I, II, and III are the most abundant. Each collagen type serves a distinct function, aiding the formation of diverse tissues, ranging from our skin and bones to blood vessels and digestive system.

The Role of Collagen in Skin Health

The health and appearance of our skin are significantly affected by collagen. This protein is a crucial constituent that offers structure, elasticity, resilience, and firmness to our skin. It is integral in the replenishment of dead skin cells and shields the skin against harm. As we get older, collagen production in our skin wanes, leading to familiar ageing signs like wrinkles and loose skin. Low collagen levels can result in diminished skin elasticity. However, on a positive note, studies indicate that collagen supplements may enhance skin elasticity and hydration, leading to healthier and more youthful-looking skin.

How does collagen aid in maintaining skin hydration?

Collagen helps keep skin hydration by fortifying the skin and contributing to its elasticity and moisture content. As a protein, collagen impacts skin physiology and upholds skin structure, allowing the skin to hold water, and supports a smooth, sturdy, and firm skin. The strengthening and hydrating properties of collagen contribute to preserving smooth and elastic skin, minimising the presence of fine lines and wrinkles. Inside our skin, collagen also assists in retaining hydration, which is a critical issue for individuals with skin conditions like eczema, as prolonged skin dehydration can result in cracks and fissures. Collagen imbues the skin with strength and firmness, and maintaining an abundant level of collagen is crucial to supporting structural health.

Collagen Production and the Ageing Process

As we mature, the natural production of collagen in our bodies decreases. After 20 years of age, the dermis layer of our skin begins to generate 1% less collagen each year. This reduction in collagen synthesis is a standard part of ageing, but it can leave noticeable effects on our skin, joints, and bones. Diminished collagen levels can result in wrinkles, sagging skin, joint discomfort, and decreased bone density. Nonetheless, by understanding collagen's function in our bodies and taking measures to sustain our collagen levels, we can help curb some of these age-associated transformations.

Top 4 Benefits of Collagen Supplements for Skin

  1. Enhanced Skin Health: Collagen supplements, particularly collagen peptides, have been discovered to decelerate the ageing process of the skin by reducing wrinkles and dryness, contributing to its strength, elasticity, and hydration.
  2. Hydration and Moisture: Collagen aids in preserving skin hydration, which is crucial for healthy skin. Extended skin dehydration can lead to cracks and fissures, especially for individuals with skin conditions like eczema. By supporting hydration, collagen supplements can aid in maintaining smooth and elastic skin.
  3. Reduction of Wrinkles: Collagen supplements have been observed to decrease the appearance of wrinkles and skin roughness. Improving skin firmness, suppleness, and moisture content, making wrinkles less conspicuous.
  4. Elasticity and Plumpness: Collagen supplements may stimulate the production of elastin, a protein that enhances skin elasticity. This can result in tighter and fuller skin, contributing to a youthful appearance.

Potential Side Effects of Collagen Supplements

Nonetheless, similar to any supplement, it's crucial to consider potential side effects and interactions. Most individuals tolerate collagen supplements well, but some might experience minor side effects like bloating, heartburn, or a bad taste in the mouth. It's also worth mentioning that collagen supplements are often sourced from common food allergens like fish and eggs, so those with allergies should select their supplements cautiously. Always consult with a healthcare professional before commencing any new supplement routine.

Diet and Collagen-Rich Foods

Although supplements provide a convenient method to boost our collagen intake, they're not the sole option. Various foods are naturally rich in collagen and can aid our body's collagen synthesis. Some collagen-rich foods include:

Animal skin and bones, for instance, chicken skin and bone broth Fish, especially the skin Egg whites Along with these, a balanced diet abundant in protein, vitamin C, and other nutrients can support collagen production. Foods like citrus fruits, berries, bell peppers, and leafy greens are high in vitamin C, a vital nutrient for collagen synthesis. Therefore, remember to fill your plate with an array of colourful fruits and vegetables.

Lifestyle Factors and Collagen

Our lifestyle decisions can also notably impact our body's collagen production. Factors like smoking, excessive alcohol consumption, and extended sun exposure can degrade collagen and hasten the ageing process. On the contrary, maintaining a healthy lifestyle can help protect our collagen reserves and keep our skin looking youthful and vibrant. So, remember to shield your skin from the sun, avoid smoking, limit alcohol consumption, and nourish your body with a balanced diet.
