Sun protection advice
Effective sun protection is one of the most important steps you can take to reduce sun damage, slow skin ageing and lower your risk of skin cancer. Small changes to daily habits can make a significant difference over time.
Understanding UV exposure
Ultraviolet (UV) radiation from the sun damages skin cells even on cloudy days. UVA penetrates more deeply and contributes to ageing and some skin cancers, while UVB is responsible for burning and direct DNA damage.
UV intensity is highest around midday and in late spring and summer, but can also be significant when reflected from water, sand, snow or concrete.
Key elements of sun protection
A good sun protection routine includes:
- Sunscreen with SPF 30 or higher, broad spectrum and water resistant for outdoor activities
- Protective clothing such as long sleeved tops, high necklines and tightly woven fabrics
- Hats with a wide brim to protect face, ears and neck
- Sunglasses with UV protection to safeguard the eyes and surrounding skin
- Shade during peak sun hours, especially between 11 am and 3 pm
How to use sunscreen correctly
Sunscreen is most effective when:
- Applied generously 20 to 30 minutes before going outdoors
- Reapplied every two hours and after swimming, sweating or towel drying
- Used on all exposed areas, including ears, back of the neck, tops of feet and backs of hands
Daily use on the face and other regularly exposed sites can significantly reduce cumulative sun damage.
Special considerations
People with fair skin, a history of sunburn, previous actinic keratoses or skin cancer should be especially careful with UV exposure. Certain medications and treatments, including some topical creams and photodynamic therapy, can also increase photosensitivity.
