Sunscreen every day: how to use SPF properly
Why daily broad-spectrum SPF 30+ is the simplest anti-ageing step, how much to apply, when to reapply, and why cloudy days and windows still count.
- Broad-spectrum, SPF 30 or higher, every day
- About two finger-lengths for face and neck
- Apply 15 minutes before going out; reapply every 2 hours, and after swimming or sweating
- UV reaches the skin on cloudy days and through windows
