SPF On The Go
Whether you’re commuting, working indoors, or travelling, UV exposure never really stops. Glass filters heat and UVB, but UVA light still penetrates, meaning daylight exposure continues inside or while driving. Daily protection keeps you covered wherever you go.
Commuting
- Car windows block UVB but let most UVA through, which drives long-term ageing.
- Studies show drivers often develop more wrinkles and pigmentation on the window-facing side of the face. Source: PubMed – UVA Transmission Through Glass
- Apply SPF before leaving home - don’t rely on glass for protection.
Office Days
- Daylight through office or home windows still includes UVA.
- Apply SPF each morning and you’ll stay protected all day indoors.
- If you sit next to a bright window, consider light reapplication in the afternoon.
Travel
- UV intensity rises by about 10–12% for every 1,000 metres of altitude. Source: PubMed – Altitude and UV Radiation
- Snow, sand, and water reflect UV, increasing exposure by up to 80% in some conditions. Source: World Health Organization - UV Radiation Guide
- Carry SPF when flying or driving long distances - UV is stronger at altitude and in bright conditions.
Perspective
- Daily SPF use protects you wherever you spend your time, not just outdoors.
- Glass, cloud, and shade reduce heat, not UV exposure.
- Protecting skin every day is the simplest way to keep it healthier for life.
