Abstract:

Solar urticaria is a rare disease that causes swelling triggered by Ultraviolet Irradiation (UVA and/ or UVB) and/or visible light, and is also considered a type of physical urticaria. After a few minutes of sun exposure, an itchy or burning rash appears, which usually disappears after 1 h to 2 h. There is no specific treatment; only symptomatic treatments such as antihistamines, sun avoidance, and sunscreens are provided. We describe the case of a 30-year-old Chinese man who began to develop urticaria while playing soccer outside. After approximately 20 min of sun exposure, itching was observed and erythema and wheals appeared on the sun-exposed skin area. He was treated with antihistamines and sunscreen, with no relief. Physical shading with clothing is effective; however, physical shading of the face and other parts of the body during sports and other activities is often difficult. Therefore, we focused on exploring whether application of blemish balm cream, defined in this paper as a sunscreen cream containing foundation. An irradiation test was performed and the area where Blemish Balm cream was applied was irradiated with visible light, but no rash occurred. This case showed that Blemish Balm cream on patients could prevent wheals, by physically shaded visible light as the active wavelength.
