The skin is exposed every day to multiple invisible environmental stressors. UV radiation and air pollution are two of the main factors associated with premature skin ageing, the appearance of pigmentation spots, and a loss of radiance.
Today, photoprotection is understood as more than just sunscreen use: it is a comprehensive approach that includes daily habits and overall skin support.
UV radiation: a key environmental stressor for the skin
Ultraviolet (UV) radiation is one of the primary external factors affecting skin health. It is mainly divided into:
UVA: penetrates deeper into the skin and is associated with signs of premature ageing
UVB: affects the more superficial layers and is linked to sunburn
Both UVA and UVB contribute to oxidative stress, a natural process that can affect cells and accelerate the breakdown of collagen over time. This may contribute to the appearance of fine lines, pigmentation changes, and increased skin sensitivity.
Pollution: an additional factor in skin ageing
Alongside UV exposure, environmental pollution can also impact skin condition.
Pollutant particles may:
Contribute to oxidative stress
Disrupt the skin’s natural barrier
Be associated with low-grade inflammation in the skin
Over time, these factors may contribute to a tired-looking complexion, uneven tone, and reduced radiance.
Oxidative stress and the skin
UV exposure and pollution share a common biological pathway: oxidative stress.
This occurs when there is an imbalance between free radicals and the body’s ability to neutralise them.
Over time, oxidative stress may be associated with:
Changes in cellular structure
Gradual breakdown of collagen and elastin
Visible signs of skin ageing
Supporting the skin’s natural antioxidant defences is therefore an important aspect of long-term skincare.
A 360° approach to photoprotection
Modern skincare takes a holistic approach to daily skin support, combining external and internal strategies.
1. External protection (OUT)
Daily use of broad-spectrum SPF
Physical barrier against UV exposure
2. Internal support (IN)
A diet rich in antioxidants and essential nutrients
Nutrients that help support the skin’s normal structure and function
Lifestyle factors that contribute to overall skin health
This combined approach helps support the skin in dealing with daily environmental stressors.
Antioxidants and skin health
Antioxidants play a key role in protecting cells from oxidative stress.
Key nutrients commonly associated with skin health include:
- Vitamin C: contributes to normal collagen formation
- Astaxanthin: a potent antioxidant
- Lycopene and lutein: help support the skin against environmental stress
- Resveratrol: supports normal cellular function
Together, these nutrients contribute to the body’s natural antioxidant network.
Supporting the skin from within
Experts increasingly recognise the importance of a holistic approach to skin health.
Rather than relying on a single solution, skin wellbeing is best supported through a combination of:
- A balanced diet rich in fruits, vegetables, healthy fats, and adequate protein
- Sufficient sleep to support natural skin renewal processes
- Regular physical activity to support circulation and oxygenation
- Daily sun protection to help reduce UV exposure
Where appropriate, targeted nutritional supplementation may also be considered to support dietary intake.
Year-round skin protection matters
A common misconception is that sun protection is only necessary in summer.
In reality:
- UVA rays are present throughout the year
- Environmental pollution affects the skin daily
- Cumulative exposure contributes to long-term skin changes
For this reason, consistent year-round photoprotection and skincare habits are important for maintaining healthy-looking skin over time.
