How to Treat Intertrigo: The Overlooked Rash in Skin Folds

Intertrigo, or intertriginous dermatitis, is a common skin condition in areas where the skin folds, such as the armpits, groin, under the breasts, neck, and between the toes or fingers. Excess moisture, friction between skin surfaces, heat, and poor air circulation cause it.

Affected skin may become red, itchy, sore, and sometimes cracked or oozing if an infection develops. While not contagious, intertrigo can cause significant discomfort and interfere with daily activities.

What Causes Intertrigo?

Several factors can trigger intertrigo, including:

• Excess moisture, such as from sweat or bodily fluids
• Skin-to-skin friction, especially in people who are overweight
• Warm, moist, and enclosed areas of skin, such as under the breasts or belly folds
• Lack of proper airflow
• Secondary infections caused by fungi, bacteria, or viruses

Symptoms can worsen if the affected area remains wet or continues to rub. Infections may cause the rash to emit an unpleasant odour.

How to Treat It

Treatment depends on the severity of the condition and whether there is an associated infection:

1. Keep the Area Clean and Dry

This is the most crucial step. Use a gentle, fragrance-free soap, rinse thoroughly, and pat the area dry—avoid rubbing harshly. A handheld showerhead can help reach tricky folds.

2. Use a Regenerative Cream

To soothe inflammation and promote skin repair, apply a product like wund+™ Regeneration Cream. It moisturizes and helps restore the skin’s protective barrier without irritation.

3. Protect Against Infection

If the skin is broken or at risk of infection, spray with wund+™ Wound Spray, which contains hypochlorous acid. It is a gentle, sting-free antiseptic that is effective against bacteria and fungi that commonly cause skin infections.

4. Treat Any Scarring

For recurring irritation that leads to dark marks or scarring, use wund+™ Scar Gel. Its stem cell-based Centella Asiatica formula helps support skin regeneration and fades residual blemishes.

Tips to Prevent Recurrence

Preventing intertrigo is better than having to treat it. Here are some preventive tips:

• Wear loose, breathable clothing made of cotton that absorbs sweat
• Maintain a healthy weight to reduce skin fold friction
• Use an antifungal powder in skin folds (avoid regular powder or cornstarch)
• Limit prolonged contact with sweat, urine, or stool—use absorbent pads if needed
• Use air conditioning or a dehumidifier in hot and humid environments
• Dry yourself thoroughly after bathing or exercising
• Wear open footwear if intertrigo affects areas between your toes
• Manage chronic conditions such as diabetes effectively
• Avoid harsh soaps or fragranced creams that can worsen irritation
• Refrain from scratching, as it can cause open wounds and increase the risk of infection

If symptoms worsen or you notice discharge or a foul odor, consult a doctor.

The wund+™ can be a helpful part of your daily skincare routine, especially if you’re prone to rashes, irritation in skin folds, friction, or moisture-related wounds.
