Collagen is the most abundant protein in the human body. It is the structural framework that gives our skin firmness, elasticity, and resilience. But collagen is not infinite, and its decline is one of the most significant contributors to visible skin ageing.
Why Collagen Declines
From our mid-to-late 20s, collagen production begins to slow. Each year, we produce around 1% less collagen, and the quality of the collagen we do make becomes less organised and less effective at supporting the skin’s structure.
This decline is influenced by:
-
Chronological ageing: the natural slowdown of cellular processes
-
Sun exposure: UV light accelerates collagen breakdown
-
Lifestyle factors: smoking, poor diet, stress, and lack of sleep can all compromise collagen health
Over time, this loss appears as fine lines, skin laxity, hollowness, and a less smooth skin surface.
Why Rebuilding Collagen Takes Time
Unlike hydration, which can be improved almost instantly with skincare, collagen rebuilding is a slow process. Once triggered, the body needs weeks to lay down new collagen fibres. These fibres continue to mature and strengthen for months.
This is why in-clinic collagen stimulation treatments are often planned in courses, with results building gradually over three to six months and continuing to improve with the right maintenance.
Treatments vs. Topicals and Supplements
There is a lot of marketing around collagen creams and supplements, but the science tells a more nuanced story.
Topical collagen:
Collagen molecules are too large to penetrate the skin barrier. While collagen-containing creams can help with hydration, they do not directly boost collagen levels in the dermis. To stimulate collagen production, treatments must trigger a controlled healing response in the skin.
Even high-profile product launches, such as the recently released collagen-infused face sculpting wrap from Skims, fall into the same category. While innovative in design, the collagen within the material cannot enter the dermis where structural change occurs. Any benefit is likely related to temporary compression, hydration, or cooling, rather than true collagen rebuilding.
Examples include:
Collagen supplements:
When consumed, collagen is broken down into amino acids during digestion in the same way as any other protein source. While some studies suggest hydrolysed collagen peptides may support skin health, results are often modest and vary between individuals. A balanced diet that includes protein, vitamin C, zinc, and healthy fats can provide the same building blocks for collagen synthesis without relying solely on supplements.
Why In-Clinic Treatments Work Best
Collagen stimulation treatments work directly in the dermis where collagen is formed. They create targeted micro-injuries or deliver energy into the deeper skin layers, activating fibroblasts, the cells responsible for collagen production. This bypasses the limitations of molecule size and digestion, ensuring that stimulation happens exactly where it is needed.
When combined with a nutrient-rich diet, SPF protection, and supportive home care, these treatments deliver results that topical products and supplements alone cannot match.
Collagen decline is inevitable, but how you respond to it is within your control. The most effective approach combines in-clinic collagen stimulation, a healthy lifestyle, and targeted skincare that protects and supports the skin’s structure.
At The Aesthetic Edit, we create collagen plans that are as individual as your skin because rebuilding your skin’s foundation is not about quick fixes, it is about long-term results. Book a consultation to learn more.
