Causes

Friction, trapped moisture, and lack of airflow in skin folds (under breasts, armpits, groin), leading to yeast or bacterial growth.

Prevention

Keep skin folds dry, use antiperspirants or barrier creams, and wear moisture-wicking clothing.

Treatment Options

Barrier creams (zinc oxide), topical antifungals if yeast is present, and keeping the area dry.

Myths vs. Facts

Myth: Only overweight people get intertrigo. Fact: Anyone can get it, especially athletes, babies (diaper rash), or anyone in hot climates.

When to See a Dermatologist

If the area becomes raw, oozes, or develops a strong odor, indicating a secondary infection.
