What Is Intertrigo, and What Can You Do About It?

If you've ever noticed a red, raw, or irritated rash developing in a skin fold, under the breasts, in the groin, between the thighs, or under the arms, you may be dealing with intertrigo. It's more common than most people realize, and the good news is that it's very treatable once you know what you're dealing with.

What Is Intertrigo?

Intertrigo is a skin condition that develops in areas where skin rubs against skin. The friction, combined with heat and moisture that gets trapped in skin folds, creates the perfect environment for irritation, and often for secondary infections from yeast, bacteria, or both.

It's not contagious, and it's not a sign that you're doing something wrong. Intertrigo can happen to anyone, though certain factors do make it more likely.

Who Is Most at Risk?

Several things can increase your chances of developing intertrigo:

• Body weight - More skin folds mean more areas where moisture can become trapped.

• Diabetes - Higher blood sugar levels promote yeast and bacterial growth.

• Hot, humid weather - Heat and sweat make skin folds a breeding ground for irritation.

• Tight or non-breathable clothing - Synthetic fabrics that don't wick moisture away make things worse.

• Incontinence - Prolonged moisture exposure from urine or stool is a significant trigger.

• Infants and young children - Diaper rash is actually a form of intertrigo.

What Does It Look and Feel Like?

Intertrigo typically appears as a reddish-brown rash that may be raw, weeping, or crusty. Common symptoms include:

• Itching or burning in the affected area

• A foul odor (especially when a secondary infection is present)

• Skin that looks macerated (soft and waterlogged)

• In more severe cases, cracking, bleeding, or oozing

When yeast (most commonly Candida) gets involved, you may notice satellite lesions — small red bumps or pustules just outside the main rash. A bacterial infection can make the area smell more strongly and feel more painful.

How Is It Treated?

Treatment depends on whether a secondary infection has developed.

For uncomplicated intertrigo, the main goals are keeping the area dry and reducing friction. This can mean:

• Gently cleaning and thoroughly drying the affected skin

• Applying a barrier cream or powder (like zinc oxide) to reduce moisture and friction

• Wearing loose, breathable clothing

• Placing a soft cloth or absorbent dressing between skin folds if needed

If yeast is involved, your dermatologist will likely recommend an antifungal cream such as clotrimazole or miconazole.

If bacteria are the culprit, a topical or oral antibiotic may be prescribed.

Low-potency topical corticosteroids are sometimes used for a short period to reduce inflammation and relieve itching, but should be used carefully in skin folds, as this skin is thinner and more prone to side effects from prolonged steroid use.

Can It Come Back?

Yes, intertrigo tends to recur, especially if the underlying conditions (excess moisture, friction, or diabetes) aren't addressed. The good news is that consistent skin care habits can significantly reduce flare-ups.

When Should You See a Dermatologist?

You should make an appointment if:

• The rash isn't improving after a few days of home care

• The affected area is spreading, blistering, or bleeding

• There's significant pain or a strong odor

• You're not sure whether it's intertrigo or something else (like psoriasis, eczema, or a fungal infection)

A dermatologist can examine the area, determine whether an infection is involved, and tailor a treatment plan to your specific situation.

The Bottom Line

Intertrigo is a common, manageable condition, but it can become more difficult to treat if it's left alone or misidentified. If you're dealing with a persistent rash in a skin fold, don't wait it out. Early treatment makes a real difference, and your dermatologist is here to help.
