Collagen is often called the building block of healthy skin—and for good reason. It is the most abundant protein in the human body and provides the structure that keeps skin firm, smooth and resilient.
As collagen levels naturally decline with age, many of the visible signs of ageing begin to appear.
What Is Collagen?
Collagen is a structural protein found throughout the body, including the skin, hair, bones, muscles and connective tissues.
Within the skin, collagen provides strength, elasticity and support. Together with elastin and hyaluronic acid, collagen helps maintain a youthful, healthy complexion.
Why Does Collagen Decline?
From our mid-20s onwards, collagen production gradually slows.
Several factors accelerate this process, including:
- Ageing
- Sun exposure
- Smoking
- Pollution
- Stress
- Poor nutrition
- Lack of sleep
As collagen decreases, skin becomes thinner, less elastic and more prone to wrinkles.
Signs of Collagen Loss
Common signs include:
- Fine lines
- Wrinkles
- Sagging skin
- Loss of firmness
- Dryness
- Dull complexion
- Slower skin repair
Collagen also contributes to healthy hair by supporting the scalp and surrounding connective tissues.
Can You Increase Collagen Naturally?
While ageing cannot be stopped, there are ways to support healthy collagen production.
These include:
- Wearing sunscreen daily
- Eating a balanced diet rich in protein and vitamin C
- Avoiding smoking
- Managing stress
- Getting adequate sleep
- Using evidence-based skincare ingredients
Ingredients such as copper peptides help support the skin's natural collagen production rather than simply masking visible signs of ageing.
Why Collagen Matters for Healthy Ageing
Healthy collagen contributes to skin that feels stronger, smoother and more resilient.
Supporting collagen production is one of the most effective long-term strategies for maintaining healthy skin and hair.
Instead of focusing only on reducing wrinkles, modern skincare increasingly aims to support the skin's natural ability to repair and regenerate itself.
