What is Collagen and why should we care?

November 27, 2025

Let’s talk about Collagen

The building block of our skin

It’s one of the biggest buzz words in the Aesthetics world-and for very good reasons…

Collagen is the key building-block structural protein keeping our skin youthful, firm and smooth.

Here’s the science behind it-and the treatments to optimise it!

Collagen is a protein that acts as a scaffolder in the skin. It provides:

It works alongside Elastin (for stretch) and Hyaluronic Acid (for hydration) to maintain a healthy, youthful appearance. As long as collagen levels remain high, the skin will look plump and resilient.

The bad news?

Collagen starts to decline from around age 25. Production naturally peaks in your late teens and early twenties. From the mid twenties, the body starts to produce 1-1.5% less collagen per year. 

This is a normal (sadly) part of ageing but can be accelerated by UV exposure, Alcohol, Smoking, Stress, Pollution, Poor sleep and poor diet.

How quickly do we lose collagen?

On average:

These biological processes explained why people start to notice visible ageing in their 30s with a more dramatic change in their 40’s and 50’s. 

The good news: can collagen loss be delayed or reversed?

Here’s what works:

– Daily SPF

THE most powerful anti-ageing product bar none is a broad spectrum SPF, ideally SPF 50. Daily use protects against UV-induced collagen breakdown and prevents premature ageing.

– Active Skincare 

– Aesthetic treatments

Modern aesthetic medicine offers several highly effective collagen-stimulating treatments:
