Ultraviolet exposure contributes to pigmentation, premature ageing and skin cancer risk. Most of that exposure is incidental rather than from deliberate sunbathing.
Choosing and using sunscreen
Use a broad-spectrum sunscreen every morning, including on cloudy days and indoors near windows. The most common mistake is applying too little: roughly two finger-lengths of product is needed for the face and neck.
Reapplication matters
Sunscreen wears off with sweat, water and time. Reapply every two to three hours when you are outdoors. For pigmentation concerns, a tinted formulation adds protection against visible light as well.
Protection beyond sunscreen
Sunscreen works best alongside physical measures. Shade, wide-brimmed hats, sunglasses, long sleeves and window film all reduce total exposure, particularly during peak hours.
- Avoid peak midday sun where possible
- Wear a wide-brimmed hat and sunglasses
- Consider window film for cars and desks near windows
- Reapply sunscreen through the day
Key takeaway
Apply enough sunscreen, reapply it, and combine it with shade and clothing for meaningful protection.
