Actinic (Solar) Purpura

Senile Purpura

Overview

Actinic purpura, also called solar purpura or senile purpura, is a common benign condition caused by sun damage and aging that weakens blood vessel walls and the surrounding connective tissue in the skin. This leads to easy bruising, producing dark purple or red blotches, typically on the forearms and hands, from minor trauma or even without noticeable injury.

Key Symptoms

• Dark purple or red irregularly shaped patches on the skin
• Flat, non-raised lesions that do not blanch with pressure
• Most common on forearms and dorsal hands
• Bruises appear with minimal or no trauma
• Lesions resolve slowly over 1–3 weeks, often leaving brown discoloration
• Thin, fragile, easily torn skin in affected areas

Affected Areas

Forearms, Dorsal hands, Arms, Any sun-damaged skin

Care Instructions

1. No specific treatment is required as this is a benign condition.
2. Protect skin from further sun damage with SPF 30+ sunscreen and protective clothing.
3. Avoid blood thinners and NSAIDs if possible (consult your doctor before stopping medications).
4. Use moisturizers to help maintain skin integrity.
5. Wear long sleeves to protect fragile forearm skin from trauma.
6. See a dermatologist if bruising is unusually severe or widespread to rule out other causes.
