Fungal skin infections are among the most common conditions seen in dermatology clinics across Australia. While often mild, they can cause discomfort, spread easily, and in some cases, become persistent without proper treatment.
At Skin Check Australia, our skin specialists provide accurate diagnosis and evidence-based management for all types of fungal infections — helping you achieve clearer, healthier skin.
What Is a Fungal Skin Infection?
Fungal infections (also called mycoses) occur when microscopic fungi invade the skin, hair, or nails.
These fungi thrive in warm, moist environments — such as between the toes, under the breasts, or in skin folds — and spread through direct contact, contaminated surfaces, or shared personal items.
Common Types of Fungal Infections
1. Tinea (Ringworm)
- Cause: Dermatophyte fungi
- Appearance: Circular, scaly red patches with raised edges
- Locations:
- Tinea corporis (body)
- Tinea pedis (athlete’s foot)
- Tinea cruris (groin, “jock itch”)
- Tinea capitis (scalp)
- Symptoms: Itching, flaking, cracking skin, and ring-shaped rash
2. Yeast Infections (Candida)
- Cause: Candida albicans, a naturally occurring yeast
- Appearance: Red, shiny patches with small satellite pustules
- Common areas: Skin folds, under breasts, groin, or diaper area
- Triggers: Humidity, sweating, antibiotics, diabetes, or immunosuppression
3. Nail Fungal Infections (Onychomycosis)
- Appearance: Thickened, discoloured, or crumbly nails
- Often affects: Toenails, sometimes fingernails
- Risk factors: Closed footwear, public pools, nail trauma
4. Pityriasis Versicolor
- Cause: Overgrowth of Malassezia yeast on the skin
- Appearance: Patches of lighter or darker skin, often on the chest, back, or shoulders
- Common in: Teenagers and adults in humid climates
How Fungal Infections Are Diagnosed
At Skin Check Australia, we begin with a clinical skin examination and dermoscopy to assess the pattern and depth of infection.
When needed, we may perform a skin scraping or nail clipping for microscopy and culture to identify the specific fungal species — allowing targeted treatment.
