Skin ageing is not just about getting older. Everyday factors like sun exposure, pollution and stress can speed things up by triggering oxidative damage.
The good news is that once you understand what is happening, it becomes much easier to protect your skin and help maintain smooth, firm, healthy-looking skin over time.
So, what is oxidative damage?
Oxidative damage happens when there is an imbalance between free radicals and your body’s ability to deal with them.
Free radicals are unstable molecules that can damage skin cells, affect DNA and speed up visible ageing. When too many build up, it leads to oxidative stress, which is one of the main reasons skin starts to lose its glow and structure.
What causes it?
A lot of it comes down to daily habits and your environment. The main triggers are:
- UV exposure
- Pollution
- Lack of sleep
- Stress
- Poor diet
All of these increase free radicals in the body, which then affect how your skin looks and feels. Over time, this can show up as fine lines, uneven skin tone, loss of firmness and a dull, tired appearance.
Why collagen matters
Collagen is what keeps your skin firm, smooth and bouncy. But oxidative stress breaks it down and slows the body’s natural production.
Over time, this can lead to thinner, less elastic skin that is more prone to wrinkles. Protecting collagen is a key part of maintaining healthy-looking skin.
Your skin’s natural defence
Your body already has its own way of dealing with free radicals. This is your antioxidant defence system.
Antioxidants help neutralise damage, support collagen, reduce inflammation and keep the skin renewing itself properly. The stronger this system is, the better your skin can cope with everyday stressors.
Key antioxidants to know
Different antioxidants support the skin in different ways, and they work best together:
- Vitamin C helps support collagen production
- Astaxanthin helps protect against sun-related damage
- Resveratrol supports the skin under oxidative stress
- Lycopene and lutein help defend against UV exposure and pollution
- Selenium supports overall cellular protection
It is the combination of these that makes the biggest difference.
Looking after your skin from within
Skincare is not just about what you apply on the surface. What you eat and how you look after yourself also has a direct impact on your skin.
Eating a diet rich in antioxidants helps support your skin’s natural defence system from within and gives a more balanced approach to protecting it.
Simple ways to support your skin every day
A few consistent habits can go a long way:
- Wear SPF daily
- Eat plenty of antioxidant-rich foods
- Avoid too much direct sun exposure
- Get enough sleep
- Manage stress where possible
It does not have to be perfect. What matters most is consistency over time.
