(Candidal skin infection; Mucocutaneous Candidiasis)
A yeast infection is a skin infection from a type of fungus. It is most common in folds of skin, between toes or fingers, and in the mouth and genitals. It is often easy to treat.
A yeast infection is caused by an overgrowth of yeast on the skin. Bacteria and yeast are normally found on the skin. They usually keep each other under control. Sometimes there is an imbalance that causes yeast to grow too much. Yeast also grows in moist conditions.
Yeast skin infections are more common in warm, humid climates.
Other things that raise the risk are:
- A weak immune system
- Certain medicines, such as antibiotics
- Uncontrolled diabetes

Symptoms of a yeast infection of the skin may be:
- Scaly rash
- Red patches of skin
- Skin breakdown
The doctor will ask about symptoms and past health. A physical exam will be done. The diagnosis may be made based on how the rash looks.
The doctor may scrape and test a small area of skin. This will confirm the presence of yeast and rule out other causes.
The goal is to clear the infection. Most yeast infections are treated with:
- Skin care—keeping the area clean and dry
- Antifungal medicine applied to the skin or taken by mouth—depending on the extent of the infection
Sometimes, a steroid ointment or lotion is also applied to the skin. This helps ease inflammation.
The risk of a yeast infection can be reduced by:
- Keeping skin clean and dry
- Wearing loose clothing with natural fibers
- Changing wet clothing as soon as possible
- Maintaining a healthy weight
- Managing health conditions, such as diabetes
