Eczema & Dermatitis

Intertrigo

WHAT IS IT

A rash in skin folds from moisture & rubbing

HOW COMMON

Very common, especially in skin folds

CONTAGIOUS?

No — but yeast or bacteria can join in

CURABLE?

Yes, and manageable with good skin care

What Is It?

Intertrigo is a red, irritated rash that forms where skin rubs against skin and traps moisture — under the breasts, in the groin, armpits, belly folds, or between the toes. It can sting or itch, and yeast or bacteria sometimes grow in the warm, damp area and make it worse.

Signs & Symptoms

  • Red or raw, sometimes shiny rash in a skin fold

  • Itching, burning, or stinging

  • Cracked, moist, or weepy skin in the crease

  • Possible odor if yeast or bacteria are involved

  • Worse with heat, sweat, and friction

Why Does It Happen?

Intertrigo happens when friction, heat, and trapped moisture irritate the skin in a fold. The warm, damp environment can then allow yeast (Candida) or bacteria to overgrow, adding to the redness and discomfort. Excess weight, sweating, heat, and diabetes all raise the risk.

Treatment Options

Treatment keeps the fold clean, dry, and protected, and treats any yeast or bacterial overgrowth. Reducing moisture and friction is the key to healing and preventing return.

KEEP IT DRY

Gently clean and thoroughly dry the fold; barrier creams protect the skin.

ANTIFUNGAL CREAMS

Used when yeast is involved (common in warm, moist folds).

MILD ANTI-INFLAMMATORY

A short course of low-strength steroid can calm redness and itch.

ANTIBIOTICS

Topical or oral, only if a bacterial infection is present.

Tips for Managing It at Home

  • Keep folds clean and thoroughly dry; pat, don't rub

  • Use moisture-wicking fabric or a soft cloth to separate skin

  • Wear loose, breathable clothing and change damp clothes promptly

  • Managing weight and blood sugar lowers the risk of recurrence

When to Call Your Provider

  • The rash worsens, spreads, or won't heal with home care

  • Increasing pain, swelling, warmth, pus, or odor (infection)

  • Fever along with a worsening skin-fold rash

  • Frequent recurrences despite good skin care
