Heat Rash: How to Treat and Soothe Your Skin Deeply?

Heat rash, also known as miliaria or prickly heat, occurs when sweat becomes trapped under the skin due to heat and humidity. The result? Small red or white bumps that itch, tingle, and on dark, olive, or mixed skin tones, sometimes leave behind persistent dark spots.

So, how can you effectively treat heat rash? What steps should you take to calm inflammation, avoid scarring, and restore an even complexion?

Follow this expert “in & out” routine to:

• Immediately soothe your skin
• Prevent marks and hyperpigmentation
• Strengthen the skin barrier and avoid recurrences

Why treat heat rash without delay?

Heat rash indicates that your sweat glands (small ducts that expel sweat) are clogged. When sweat builds up under the skin, it creates local inflammation responsible for itching and tingling.

Warning: On darker skin tones, inflammation can quickly trigger post-inflammatory hyperpigmentation (PIH). Even a small rash can leave behind brown or black spots that are difficult to fade if the skin isn’t soothed in time.

Step 1: Cool the skin to stop inflammation

Why? Cooling the skin immediately reduces inflammation and lowers the risk of worsening breakouts.

Expert tips:

• Lukewarm showers (not cold): very cold water can cause rebound inflammation.
• Loose, breathable clothing: opt for cotton to reduce friction.
• Cool compresses (never ice): apply for 5 to 10 minutes on affected areas to calm the burning sensation.

Step 2: Gently cleanse to prevent infection

Why? Harsh cleansing can irritate the skin further and weaken the skin barrier, leading to new lesions.
