How to Boost Your Skin's Anti-Ageing (Collagen) Production

You may have already heard: every year from the age of 25, your rate of collagen production decreases by 1%. This means that increasing production and regulating the breakdown of this protein is key. Luckily, there are several promising ways to do exactly that. From modifications to your lifestyle and diet, through to your skincare routine, an integrated approach can make a real difference.

What is Collagen?

Collagen is the form of protein most abundant in the human body, making up a significant portion of the skin's structure. It provides the framework necessary to maintain connective tissues, bones, cartilage, and other components within the body. All while providing the shape, strength, and bounce needed for the skin to look and feel its best.

Know the Science Behind Collagen for Skin

This is the protein responsible for helping ensure a smoother, tighter skin surface. As a result, it works to reduce the visible signs of ageing, including fine lines and wrinkles. It acts as the framework in the skin's middle layer (the dermis) to provide volume and plumpness. When elastin works like a spring in the body's connective tissue, its counterpart, collagen, stops the skin from over-stretching.

Activating collagen synthesis involves stimulating fibroblasts (skin cells) that make and maintain the structural framework. Simply put, the process begins within the cell and "copies the gene" of collagen. It then builds protein chains through amino acids, forms a strand, and pushes outward from the cell into surrounding tissue. These strands are later bound together by enzymes to create collagen.

*A PubMed article notes that with age, human fibroblasts decrease in their ability to synthesise collagen. This, paired with the fact that existing collagen breaks down more readily, causes people to exhibit visible ageing, including wrinkles and rough skin texture. This suggests that methods for stimulation can be particularly beneficial in improving skin appearance.

What is Collagen Good For?

By now, we've established that this protein can be beneficial in reducing the look of ageing skin. However, there are a number of broader benefits that higher collagen levels can offer as the years go by.

How to Boost Collagen Production in Skin?

To help support your skin's collagen synthesis process, we advise an integrated approach to your routine. Relying on a single method risks only addressing one part of a broader, more complex biological system. Addressing multiple pathways simultaneously, such as improving your diet's nutritional value alongside your topical routine, tends to produce far better outcomes.

Vitamin-Rich Diet (Collagen-Rich Foods)

Certain animal and plant-based foods can support collagen synthesis by supplying the vitamins the body needs to facilitate this process. Look out for the following to fuel collagen from within.

*Please note that the above is intended to provide education on foods which may support dermal collagen. The outcome of specific dietary consumption is never guaranteed.

Protein Supplementation (Diet-Supported)

The right supplements can support collagen production. However, they should not be treated as a substitute for a nutrient-dense diet. Your body needs the right micronutrients, including vitamin C, in order to form the protein in the first place.

• Marine

  Derived from fish skin, it is rich in Type I collagen, the primary structural protein found in the human body. A strong choice for skin-focused supplementation.

• Bovine

  Found in animal bones. High in both Type I (main structural protein) and Type III (supporting structural protein) collagen, making it a well-rounded option.

• Chicken

  Present in cartilage. Provides a rich source of Type II collagen, which supports shock absorption in the joints.

• Porcine

  The closest genetic resemblance to humans. Provides Type I and Type III collagen, closely mirroring the proteins most abundant in the human body.

A Collagen-Friendly Lifestyle: Daily Habitual Checklist

A balanced diet and targeted supplements are key, but the right daily habits are equally important. Take the time to review your day-to-day routine and make adjustments where possible.

• ☀
  UV Ray Protection

  Australia has some of the highest UV levels in the world. UV damage causes collagen to break down faster. If the UV index is three or above, apply SPF 50+. The Cancer Council recommends reapplication every two hours, and immediately after swimming, towel drying, or any sweat-inducing activity.

• 🧘
  Stress Management

  While stress can cause temporary side effects like headaches, over time it can also destroy collagen. The stress hormone cortisol triggers enzymes that break down existing collagen and prevent new collagen from forming. Practice healthy habits like regular exercise and screen breaks.

• 💤
  Adequate Sleep

  Deep sleep is the primary window in which fibroblasts become active and produce collagen and elastin. Disrupted sleep prevents these processes from occurring properly. Aim for seven to nine hours per night.

• 🚫
  Limit Alcohol and Tobacco

  Excess alcohol causes dehydration that impairs the skin barrier. Tobacco generates free radicals that directly damage proteins like collagen. Minimise consumption of both as much as possible.

Over-the-Counter (OTC) Skincare Products

The right skincare products contain collagen that has been broken down in the lab into smaller fragments, allowing the skin to absorb them more readily. This signals to cells to grow new collagen and also acts as a humectant on the skin's surface.

When selecting products to support collagen renewal, look for formulations with these key ingredients, found in concentrated moisturisers and serums.

• Niacinamide for Collagen

  Provides metabolic support to fibroblasts to better synthesise collagen and elastin. It not only helps create proteins but also interferes with enzymes responsible for their destruction. Niacinamide also protects and preserves the skin barrier to prevent excess transepidermal water loss.

• Peptides for Skin Ageing

  Peptides send direct signals to fibroblasts to create collagen and elastin. They also reduce the rate at which existing collagen breaks down, helping to preserve skin firmness over time.

• Vitamin C and Collagen

  Vitamin C is the essential tool used by enzymes to shape and build collagen. Without it, the collagen ropes formed aren't strong enough to hold their structure. It also neutralises free radicals that cause premature protein breakdown, acting as an antioxidant for the skin.

• Retinol for Ageing Skin

  This notable active ingredient penetrates the skin and converts into retinoic acid, which then activates fibroblasts. A PubMed article notes that topical retinol applied to aged human skin causes major changes, transforming both the epidermis and the dermis.

Explore Professional Laser Treatments for Collagen Loss with Age

Over-the-counter skincare can deliver collagen-supporting benefits, but these products generally have limitations in terms of penetration depth. In-clinic treatments offer the opportunity for more potent delivery to the skin's middle layer. At SDL Australia, we provide clinical treatments designed to stimulate collagen at a deeper level.
