Polymorphous Light Eruption (PMLE)
Definition: Polymorphous Light Eruption (PMLE) is a sun-induced rash that occurs after the first significant sun exposure in the spring or summer. It presents as red, itchy bumps or blisters.
Cause: PMLE is caused by a sensitivity to UV light, particularly UVA rays.
Types:
- Mild PMLE: Causes small red spots on exposed skin.
- Severe PMLE: Results in blisters or plaques.
Protection Before the Cause: - Gradually increase sun exposure over time to build skin tolerance.
- Apply broad-spectrum sunscreen and wear UV-protective clothing.
Cure After the Cause: - Use anti-itch creams and cold compresses to relieve symptoms.
- Oral antihistamines or corticosteroids may be prescribed for severe cases.
Conclusion: PMLE is common in those with sensitive skin, but sun protection can prevent flare-ups, and most symptoms resolve with time.
