Intertrigo Under the Breasts: Home Care

The fold beneath the breast combines warmth, sweat and skin-to-skin contact. Bra edges and movement can add friction, leaving skin red, itchy, stinging, tender or cracked. Moisture can allow yeast to multiply, and a rash with small nearby spots may need assessment for [Skin Yeast Infection](/conditions/cutaneous-candidiasis/). The broader condition is called [Intertrigo](/conditions/intertrigo/), and it can affect people with any body shape.

Clean the fold with lukewarm water and a mild, fragrance-free cleanser, then pat it dry. A cool hairdryer setting can help reach the crease without rubbing. Wear a well-fitting, breathable bra and change it after sweating. A fresh, soft cotton or moisture-wicking cloth can separate the skin, but replace it whenever damp and wash it regularly. Avoid fragranced creams, scrubbing, tight synthetic fabric and household remedies that sting. If a clinician confirms yeast, [Topical Antifungal Treatment](/treatments/medical-dermatology/topical-antifungal-therapy/) may be advised. If sweating drives repeated episodes, ask about [Prescription Antiperspirant](/treatments/medical-dermatology/prescription-antiperspirant/).

Arrange a review if the rash does not improve, keeps returning, bleeds, cracks deeply, smells unpleasant or causes significant pain. Seek prompt care for pus, fever, rapidly spreading redness, increasing warmth, swelling or red streaks. Do not assume every rash beneath the breast is intertrigo: contact allergy, eczema and infection can look similar and require different treatment.

Could this be yeast or contact irritation? Is a cloth barrier suitable for my skin? Which cleanser, cream or antifungal should I use? How should I manage sweating, bra friction and recurrence?
