As temperatures rise and the days become longer across the UK, spending more time outdoors becomes part of daily life. While sunlight can positively impact mood and vitamin D levels, it is also important to understand the risks associated with UV (Ultraviolet) radiation and how to properly protect your skin.
At Dottore London, we believe prevention and awareness are essential when it comes to long-term skin health.
What Is UV Radiation?
Ultraviolet (UV) radiation is a form of invisible energy produced naturally by the sun. Prolonged exposure to UV rays can damage skin cells, accelerate skin ageing, and increase the risk of developing skin cancer.
There are three main types of UV radiation:
- UVA Rays
These penetrate deep into the skin and are primarily responsible for premature ageing, wrinkles, and long-term skin damage. - UVB Rays
These affect the outer layers of the skin and are the main cause of sunburn. UVB exposure also plays a major role in the development of skin cancer. - UVC Rays
These are the most harmful rays but are absorbed by the Earth’s atmosphere and do not usually reach the ground.

Why UV Protection Matters in the UK
Many people associate sun damage with hot countries or summer holidays abroad, but UV radiation can still be strong in the UK — even on cloudy or cooler days.
Between mid-March and mid-October, UV levels in the UK are often high enough to damage the skin, particularly during the middle of the day.
Repeated exposure without adequate protection can lead to:
- Premature skin ageing
- Pigmentation and sun spots
- Eye damage
- Weakened immune response in the skin
- Increased risk of melanoma and non-melanoma skin cancers
According to health experts, the majority of melanoma skin cancer cases could be prevented through safer sun exposure habits and by avoiding sunbeds.
How to Protect Yourself from UV Radiation
Protecting your skin does not mean avoiding the outdoors — it means adopting healthy and consistent habits.
Wear Sunscreen Daily
Use a broad-spectrum sunscreen with at least SPF 30 and apply it generously to exposed skin, even when it is cloudy. Reapply every two hours, especially after sweating or swimming.
Avoid Peak Sun Hours
UV rays are strongest between 11am and 3pm. Whenever possible, seek shade during these hours.
Wear Protective Clothing
Sunglasses with UV protection, hats, and lightweight long-sleeved clothing can help reduce direct exposure.
Avoid Sunbeds
Artificial UV radiation from sunbeds significantly increases the risk of skin cancer and premature ageing.
Monitor Your Skin
Keep an eye on new moles or changes in existing marks, freckles, or lesions. Early detection is one of the most important factors in successful treatment outcomes.
When Should You Book a Skin Check?
It is important to speak with a specialist if you notice:
- A mole changing shape, size, or colour
- Persistent itching or bleeding
- New or unusual skin lesions
- Areas of skin that do not heal properly
Professional skin assessments can help identify concerns early and provide peace of mind.
