Sun-Induced Skin Rashes

Photodermatoses Characteristics

• Chronic actinic dermatitis (CAD) manifests as persistent dermatitis on chronically sun-exposed skin, more common in older individuals with cumulative sun damage, according to the British Journal of Dermatology 1, 2

Prevention and Risk Factors

• The Centers for Disease Control and Prevention (CDC) recommends minimizing sun exposure during peak UV hours (10 AM - 4 PM, especially 11 AM - 1 PM) and using broad-spectrum sunscreens with SPF ≥15 providing both UVA and UVB protection 3, 4, 5
• Cloud cover provides minimal protection, with 80% of UV rays penetrating light clouds, and reflective surfaces such as water, sand, snow, and pavement increase UV radiation reaching the skin 3, 4, 5
• Fair-skinned individuals with red/blond hair who burn easily face the highest risk for all photodermatoses 3, 4
