What causes underarm rash and how can I care for it?

What is an armpit rash?

An underarm rash is any change in the skin under your arms that results in redness, itchiness, bumps, flakiness or swelling. It can look different depending on the cause of irritation, ranging from small red dots to dry or even broken skin. But don’t worry – most underarm irritation is temporary and easy to care for once you identify the cause. 

What causes armpit rash?

From shaving to sweating, our underarms go through a lot, which can lead to irritation or changes in skin texture. Common triggers include:

• Shaving, which can cause skin barrier damage, razor burn, ingrown hairs or micro-cuts.
• Tight or synthetic clothing, which can trap moisture and cause chafing.
• Trapped sweat in sweat glands in your skin, which can develop heat rash.
• Stress or hormonal changes, which can trigger sensitivity or sweating.
• Skin conditions like eczema, bacterial infections or allergic reactions.

How can you help care for underarm irritation?

• Give your skin a break: Pause shaving and switch to loose, breathable clothing to minimize friction and chafing while your underarms heal.
• Keep underarms dry and clean: Gently cleanse with lukewarm water and a mild, moisturizing formula (like our Dove body washes), then gently pat dry.
• Apply an over-the-counter treatment if needed. For inflammatory rashes, a thin layer of hydrocortisone cream can help. If you suspect it’s a yeast infection, try an anti-fungal cream or powder instead. If your armpit rash persists, speak with a medical professional.
