Your Complete Guide to Collagen in 2024

Is your skin beginning to lose its youthful radiance?

Or perhaps you’ve noticed it becoming thinner and slightly craggier?

As you enter your 30s, collagen, the structural foundation of your skin, deteriorates.

This is when the telltale signs of ageing kick in.

So, if you’re considering the benefits of collagen to smooth your facial lines, join us.

As we explore one of the most celebrated proteins available.

What is Collagen?

Collagen, in essence, is the internal scaffolding deep within your dermis, serving as the structural protein.

It boasts higher concentrations in ligaments and tendons and contributes to approximately one-third of your body’s overall protein makeup.

Over the years, your body progressively produces less collagen; research (1) has found that this decline typically begins in your 20s, equating to roughly a one-percent reduction in collagen production each year.

Beyond the natural ageing process, external factors such as excessive sun exposure, smoking, and exposure to environmental pollutants can further hasten this breakdown of collagen.

There are 29 different types of collagen, as this study (2) demonstrates.

The primary sources of protein you should know about are types I, II, III, and IV:

    1. Type I: This type constitutes a staggering 90% of your body’s collagen and plays a pivotal role in providing structural support to your skin, connective tissues, teeth, tendons, bones, and fibrous cartilage.
    2. Type II: Unlike type I, type II is less densely packed and more abundant in your joints’ cushioning.
    3. Type III: Similar to type I, type III contributes to the structural integrity of your muscles, organs, and arteries, supporting these vital components.
    4. Type IV: Type IV is instrumental in filtration processes and is typically found within the layers of your skin.

These complex collagen types begin to explain collagen’s crucial role in helping maintain the structure and function of many of your skin’s tissues.

Can you Boost collagen?

This is a common question our clients often ask; misleading marketing claims sometimes lead you to believe that topical collagen application will rejuvenate the collagen in your skin in some way.

Regrettably, this is not the case, as collagen molecules, by their very nature, are large and can’t penetrate the skin when applied externally.

However, they provide a surface-level benefit by adding moisture to the skin, resulting in plumper skin thanks to collagen’s excellent moisturising properties.

When well-moisturised, your skin appears healthier and more youthful, but this effect does not come from topical absorption.

Do Collagen Supplements Work?

When you take collagen supplements internally, your body rapidly absorbs them. Some evidence suggests that internal supplementation may slow down your skin’s ageing process, diminishing fine lines and plumping your skin by stimulating the natural production of collagen, elastin, and fibrillin.

A study published in the Journal of Drugs in Dermatology (3) reveals that it can have a substantial impact on enhancing skin health, promoting a more youthful appearance through the following three primary mechanisms:

      • Enhanced Elasticity: Supplementation can thicken your dermal layer of the skin, leading to improved elasticity.
      • Moisture Retention: It helps your skin retain moisture, resulting in a plumper and more youthful appearance while preventing premature ageing.
      • Increased Density: Supplements contribute to the increased density of collagen fibres within your skin.

So, are other supplements that can help give your gorgeous collagen a good plumping?

Vitamin C

Vitamin C is a highly effective ingredient that helps to stimulate collagen production within your skin.

Ascorbic acid is a potent antioxidant that combats sun damage and inhibits melanin production, aiding in lightening dark spots.

In a previous post, “Vitamin C for Skin Health: Your Complete Guide,” we highlighted how vitamin A can reconstruct your skin’s DNA at a cellular level and foster the creation of protective barriers for your skin.

If you’re keen to begin introducing vitamin C into your skincare routine, we recommend our C+ Ascorbic Acid skin shot. This shot enhances your skin’s resilience, restoring it to its youthful, radiant state.

Vitamin A 

Incorporating vitamin A into your skincare routine can also bolster your skin’s collagen production. Vitamin A has been extensively researched for its ability to combat signs of ageing.

Try our A+ Retinoid Complex; when applied topically, it helps to revitalise dull, prematurely aged skin.

Intelligently formulated with ceramides, it buffers the sometimes irritating effects of vitamin A, helping you build your skin’s foundation and make your protective barrier more resilient.


Copper peptides are a great way to production; they activate the lysyl oxidase enzyme, a critical factor in collagen maturation.

These peptides can be found in our DNA age delay skin shot, which helps to strengthen more mature, dry, thin skin.

Alternatively, you can take a daily intake of 900 micrograms of copper, or you may want to consider incorporating foods like cashews, oysters, crab, sunflower seeds, and beef liver into your diet, which will help to boost your copper intake.

To conclude. The naked truth

Collagen is the crucial structural protein found deep within the skin, responsible for maintaining its integrity.

Your natural collagen production decreases as you age, revealing many signs of ageing, and external factors like sun exposure and smoking can also exacerbate collagen breakdown.

Topical application is often marketed as a solution, but as you can see, the large size of collagen molecules prevents them from penetrating your skin. Instead, they provide surface-level moisturisation, promoting a plumper appearance.

When taken internally, supplements have significant benefits. Studies (4) suggest they enhance your skin elasticity, retain moisture, and increase the density of your collagen, demonstrating that internal supplementation will, infact, stimulate your body’s natural collagen, elastin, and fibrillin production.

Some great ingredient supplements, like Vitamin C, A derivatives, and copper peptides, contribute to healthier, more resilient skin.

So, in conclusion, taking care of your collagen is crucial for maintaining youthful skin.
