Milia rubra is characterized by what symptoms?

Milia rubra, also known as heat rash or prickly heat, is characterized by small red vesicles, accompanied by itching of the skin. This condition typically occurs due to excessive heat and moisture, leading to a blockage of sweat glands. When the body overheats, especially in hot and humid environments, the normal perspiration process is disrupted, causing inflammation and resulting in the formation of these small, itchy red spots.

The symptoms of milia rubra are specifically linked to the body's response to heat and can manifest in areas where sweat glands are more prevalent, like under the arms or in skin folds. This condition does not result in large, painful blisters or dry flaky patches, which are symptoms related to other skin conditions. Identifying milia rubra accurately is important for effective treatment and prevention, particularly by managing exposure to heat and ensuring adequate skin ventilation.
