Guide To The Symptoms And Types Of Heat Rash

Miliaria Profunda

Miliaria profunda is a term used to describe when an individual experiences the retention of sweat deep in the sweat ducts that leaks into their dermis. The dermis is a deeper layer of the skin that is rich with blood vessels and sits below the epidermis. The sweat in the skin of an affected individual becomes trapped at the dermo-epidermal junction. Miliaria profunda is most prevalent among men who have had repeated episodes of miliaria rubra. The most common cause of the development of miliaria profunda is repeated exposure to intense heat and humidity over time. Miliaria profunda causes the development of larger and deeper-seated papules in an individual's skin that may be flesh-colored, asymptomatic, painful, and can range from one to four millimeters in size. The papules that develop from miliaria profunda can be described as white or red lumps that may feel prickly. Itchiness of the skin is not common in miliaria profunda because these papules are located below an individual's itch receptors.
