A skin yeast infection, also called cutaneous candidiasis, is a fungal infection caused by an overgrowth of Candida, most commonly Candida albicans. Candida normally lives on the skin without causing problems, but warm, moist environments can allow the yeast to multiply and cause an infection. (medlineplus.gov)
Skin yeast infections most often develop in skin folds where heat and moisture become trapped, including under the breasts, in the groin, between the buttocks, under the abdomen, between fingers or toes, and in the armpits. Babies commonly develop a yeast-related diaper rash.
A skin yeast infection is usually treatable with antifungal medications. Most infections improve with proper treatment and by keeping the affected area clean and dry.

Skin yeast infections are very common and can occur in people of all ages. They are more likely to develop in areas where skin rubs together or stays moist.
People with obesity, diabetes, weakened immune systems, or those taking antibiotics or corticosteroids may have a higher risk of developing cutaneous candidiasis. Infants commonly develop Candida diaper rash because of prolonged moisture and skin irritation.
Risk Factors for Candidiasis – CDC

Explains who is more likely to develop Candida infections and why.
Symptoms vary depending on the location and severity of the infection.
Common symptoms may include:
Common locations include:
A healthcare provider usually diagnoses a skin yeast infection by examining the rash and reviewing your symptoms and medical history.
They may ask about:
Additional testing may be recommended if the diagnosis is uncertain or the infection does not improve with treatment.

https://medlineplus.gov/fungalinfections.html
Provides information about diagnosing fungal skin infections.
Skin yeast infections occur when Candida yeast grows excessively on the skin.
Common causes and contributing factors include:
Candida thrives in moist environments. When moisture remains trapped against the skin, the normal balance of microorganisms can be disrupted, allowing yeast to multiply.
Risk Factors for Candidiasis – CDC
https://www.cdc.gov/candidiasis/risk-factors/
Explains how moisture, medications, diabetes, and immune-system changes increase the risk of Candida infections.
Several factors can worsen symptoms or delay healing.
Common factors include:
Using corticosteroid creams without confirming the diagnosis may temporarily reduce redness while allowing the fungal infection to worsen.

Most skin yeast infections improve completely with appropriate antifungal treatment.
However, infections may recur if contributing factors such as moisture, obesity, uncontrolled diabetes, or immune suppression remain present.
People with recurrent infections may need evaluation for diabetes or other medical conditions affecting the immune system.

Usually not. Candida normally lives on the skin, and most skin yeast infections are not considered highly contagious.
Poor hygiene alone does not cause Candida infections, but prolonged moisture and skin irritation may contribute.
Yes. High blood sugar increases the risk of Candida infections.
Avoid using steroid creams unless recommended by your healthcare provider, as they can worsen fungal infections.
Yes. Candida commonly causes diaper rash in infants.

This guide is intended for educational purposes only and should not replace medical advice, diagnosis, or treatment from your healthcare provider. Skin yeast infections can resemble bacterial infections, eczema, psoriasis, ringworm, contact dermatitis, and other skin conditions that require different treatments. Always use antifungal medications as directed and avoid using topical steroid creams unless recommended by your healthcare provider, as they may worsen fungal infections. Contact your healthcare provider if symptoms worsen, spread, recur frequently, or do not improve after treatment. Call 911 immediately if you experience difficulty breathing, swelling of the face or throat, loss of consciousness, or another medical emergency.
