The Indoor Sun Trap: Why Your Office Window Is a Skin Saboteur
By Dr. Mark Gray, Harvard-Trained Dermatologist and Ao Co-Founder
The Deceptive Nature of Indoor UV
Indoor UV is a sneaky foe – standard glass blocks UVB but lets 50-75% UVA through (Journal of Investigative Dermatology). A study of 84 office workers found those near windows had 170% more skin damage on exposed sides.
Standard glass blocks less than 50-75% UVA rays
Statistics on Lifetime Indoor Exposure
Alarming stat: Indoor exposure causes 65% of lifetime UVA dose (Environmental Protection Agency). Fact: UVA penetrates clouds and glass, generating free radicals that degrade collagen 24/7. Dermatology evidence from a Korean study showed office dwellers with 20% higher photoaging scores.
Amplification in Urban Environments
In urban settings like California offices, reflected UV from buildings amplifies this trap. Long-term, it leads to uneven pigmentation and weakened barriers.
Daily Strategies to Counter Indoor Risks
Daily indoor suncare is essential. Ao's Essential Sun Shield set, with mineral SPF for broad defense, traps this saboteur – preventing silent accumulation.
