Miliaria

What Is Miliaria (Heat Rash)?

Miliaria, commonly known as heat rash, is a skin condition caused by blocked sweat ducts that trap sweat beneath the skin. It often appears as small, red bumps or clear fluid-filled blisters and is most common in hot, humid environments.

At SOMA Skin & Laser, we diagnose and treat all forms of miliaria, from mild cases to more persistent or recurrent outbreaks.

Types of Miliaria

Miliaria is classified based on the depth of sweat duct blockage:

  • Miliaria crystallina – Clear, pinpoint blisters without inflammation; usually mild

  • Miliaria rubra – Red, itchy bumps (most common); often called “prickly heat”

  • Miliaria pustulosa – Inflamed, pus-filled lesions

  • Miliaria profunda – Firm, flesh-colored bumps; often in recurrent cases

Who Gets Miliaria?

While infants are most commonly affected, miliaria can occur at any age, especially:

  • In hot, humid climates

  • After fever or illness

  • During intense physical activity

  • When wearing tight or non-breathable clothing

Diagnosis & Treatment at SOMA Skin & Laser

Miliaria is typically diagnosed through a clinical skin exam. We tailor treatment based on severity and recurrence:

Treatment Options:

  • Topical soothing agents (calamine, hydrocortisone, menthol-based creams)

  • Antibacterial or anti-inflammatory agents (if pustular or infected)

  • Cooling therapies and lifestyle recommendations

  • Moisture-wicking clothing and proper skincare

In rare or resistant cases, we may recommend a short course of oral medications or consider underlying conditions contributing to sweat duct blockage.
