From the Research
Lime phytophotodermatitis is a skin reaction that occurs when certain plant compounds called furocoumarins (found in limes, lemons, celery, and other plants) contact the skin and are then exposed to UV light, and the most effective treatment involves immediately washing the affected area with soap and water, applying cool compresses to reduce inflammation, and using over-the-counter hydrocortisone cream (1%) 2-3 times daily for 3-5 days to manage symptoms, as recommended by the most recent study 1.
Causes and Symptoms
The condition is caused by the activation of furocoumarins by UV light, leading to cellular damage and an inflammatory response in the skin, resulting in characteristic reddening, blistering, and subsequent darkening of affected areas 1. The symptoms of lime phytophotodermatitis can be severe and may include blistering, extensive involvement, and hyperpigmentation that fades over months 2.
Treatment and Prevention
Treatment for severe cases with blistering or extensive involvement may include oral antihistamines like diphenhydramine (25-50mg every 6 hours) to help with itching, and topical aloe vera gel for soothing relief 3. It is essential to avoid sun exposure to the affected area until healed and use broad-spectrum sunscreen (SPF 30+) when outdoors 4. The condition typically resolves within 1-2 weeks but may leave hyperpigmentation that fades over months 5.
Key Considerations
Phytophotodermatitis can be easily misdiagnosed as other skin conditions, including fungal infection, cellulitis, allergic contact dermatitis, and even child abuse 4. Therefore, it is crucial to be aware of the condition and its causes to provide proper management and avoid unnecessary distress for patients 3.
