PMLE is a common skin condition caused by exposure to sunlight or artificial ultraviolet light. Here are the causes, symptoms, diagnosis, treatment, and prevention methods:
Symptoms of PMLE include an abnormal immune response to sunlight or artificial UV light. There is no clear cause of the condition, but some components of sunlight, including UV rays, may play a role in triggering it. A person's susceptibility to PMLE may also be influenced by genetics.
In the hours and days following sun exposure, PMLE symptoms usually manifest as red, itchy, or burning skin. The affected areas may develop raised bumps, blisters, or patches of small, red lesions. The face, neck, chest, and arms are commonly affected by these symptoms.
A comprehensive medical history of the patient as well as a physical examination of the skin are necessary to diagnose PMLE. To determine if PMLE exists, dermatologists may conduct phototesting, in which small areas of the skin are exposed to varying degrees of UV light.
PMLE treatment options include topical corticosteroids to reduce inflammation and itching, moisturizers, and antihistamines, to alleviate discomfort, and oral corticosteroids or immunosuppressive medications may be required in severe cases. Additionally, phototherapy sessions under controlled conditions may reduce the severity of symptoms over time and desensitize the skin to UV light.
In order to prevent PMLE, you need to wear protective clothing such as wide-brimmed hats and long-sleeved shirts as well as broad-spectrum sunscreen that has a high SPF rating. PMLE flare-ups can also be reduced by avoiding peak sunlight hours, usually between 10 a.m. and 4 p.m. It's important to apply sunscreen generously and reapply it every two hours, especially after swimming or sweating.
