Photoprotection: The Most Important Anti-Aging Intervention

Daily sunscreen use reduces visible aging signs by up to 24% and prevents 80% of UV-induced skin damage. Photoaging causes up to 80% of facial aging. This is the single most cost-effective anti-aging intervention available.

UV Radiation: UVB vs. UVA

• UVB (290-320nm): Epidermis; sunburn, DNA damage, skin cancer risk
• UVA (320-400nm): Dermis; collagen/elastin degradation, photoaging. Penetrates window glass — indoor exposure causes photoaging too.

SPF and PA Ratings

• SPF 15: blocks 93% UVB | SPF 30: 97% | SPF 50: 98% | SPF 100: 99%
• PA+: PPD 2-4 | PA++: PPD 4-8 | PA+++: PPD 8-16 | PA++++: PPD 16+
• For anti-aging: PA+++ or PA++++ is essential
