A skin yeast infection, most often caused by Candida, develops when this naturally occurring fungus overgrows, typically in warm, moist areas of the body such as skin folds, under the breasts, in the groin, or between fingers and toes. It causes red, itchy, sometimes sore patches, often with a slightly raised, scaly edge.

01 · Know
What is Yeast infection (skin)?
A skin yeast infection, most often caused by Candida, develops when this naturally occurring fungus overgrows, typically in warm, moist areas of the body such as skin folds, under the breasts, in the groin, or between fingers and toes. It causes red, itchy, sometimes sore patches, often with a slightly raised, scaly edge.
It's more common in warm weather, with excess sweating, in people with diabetes, or those taking antibiotics or with a weakened immune system, all of which can encourage yeast overgrowth.

Practical steps
Take these self-care steps
These measures can help ease symptoms, support recovery, and reduce the chance of things worsening — but they don't replace medical advice if symptoms are severe or persistent.
- 1Keep the area clean and thoroughly dry.Yeast thrives in moisture, so drying skin folds carefully after washing is one of the most effective preventive steps.
- 2Use an antifungal cream as directed.Apply consistently for the full recommended duration to fully clear the infection.
- 3Wear loose, breathable clothing.This reduces moisture build-up in skin folds and helps prevent recurrence.
- 4Manage underlying conditions.If you have diabetes, keeping blood sugar well controlled can help reduce the risk of yeast infections.
- 5Consider using a barrier cream in prone areas.This can help protect skin folds from moisture and friction that encourage yeast overgrowth.

BarnMD Bottom Line
Skin yeast infections usually respond well to antifungal cream and keeping the area clean and dry, though recurrent infections are worth discussing with a doctor.
Thoroughly drying skin folds after washing or sweating is one of the simplest, most effective ways to prevent yeast infections recurring.
