What are fungal skin infections?

A skin illustration shows a circular patch with a raised, scaly edge.

Some fungi can grow on the outer skin, hair or nails. Ringworm is one example: despite its name, it is caused by a fungus, not a worm. Yeasts can cause other kinds of skin rash.

These conditions do not all look the same or need the same medicine. An itchy, flaky patch can also be eczema, psoriasis or another skin problem, so appearance alone is not a reliable self-diagnosis.

Where are the symptoms?

A circular skin patch has a scaly outer edge.

Body or groin

Ringworm may form an itchy patch with a more noticeable edge. It can look red, grey or brown depending on skin tone, and does not always make a clear ring.

A foot illustration highlights flaky, cracked skin between the toes.

Feet and between the toes

Athlete’s foot can cause peeling, itching and cracks between the toes or on the sole. It may also spread to the nails.

A scaly scalp patch contains short, broken hairs.

Scalp or beard

Flaking with patchy hair loss or broken hairs needs an examination. Scalp ringworm usually needs oral prescription treatment; shampoo or skin cream alone is not enough.

A nail is thickened and has a discoloured, brittle free edge.

Nails

Fungus can make a nail thick, discoloured or crumbly. Injury and psoriasis can look similar, so a sample may be needed before choosing treatment.

Explore nail changes

Moist skin folds

Candida yeast can cause a sore rash in warm, damp folds, sometimes with small spots around it. Friction, sweating and other health factors can contribute.

Chest, back or upper arms

Pityriasis versicolor causes fine, flaky patches that may be lighter, darker or pink. It involves yeast normally found on skin and is not usually passed between people like ringworm.

Check the cause before treating it.

A small skin sample on a slide is examined under magnification.

01
Examine the pattern
The dermatologist checks the rash and may look at the feet, nails or scalp too. Mention when it began, previous episodes and whether anyone close to you has similar symptoms.
02
Consider a skin, hair or nail sample
Testing can help confirm fungus and distinguish it from other conditions. It is especially useful when the diagnosis is uncertain, treatment has failed or nail treatment is being considered.
03
Bring the products you have used
Show the labels of creams, tablets and home remedies. Some combination rash creams contain steroids that can change how ringworm looks and make it worse.

Treatment depends on the infection.

Unbranded topical products represent selected antifungal treatment.

Antifungals applied to the skin

A suitable cream, spray or other topical medicine may treat a localised skin infection. The product, area to cover and course length depend on the diagnosis.

Unbranded medicine packaging represents an assessed prescription.

Prescription treatment by mouth

Scalp infection, selected nail infections and some extensive or persistent rashes may need oral medicine. Health history, other medicines, pregnancy and possible monitoring matter.

Colour patches on the trunk represent one pattern of yeast-related rash.

Care for yeast-related rashes

Selected antifungal washes or creams may help pityriasis versicolor. Skin-fold candidiasis needs treatment suited to the area, along with reducing trapped moisture and friction.

OUR PROCEDURE

How we plan your care.

STEP 01

Identify the infection and affected areas

Review the rash and history
Discuss symptoms, earlier treatment, contact with animals and recurring infections. Tell the clinician about diabetes, immune conditions and any medicines you take.
Arrange testing when helpful
A scraping, hair sample or nail clipping may be recommended. Ask how you will receive the result and whether it could change the plan.

A sample is checked to help identify the cause.

STEP 02

Use the right medicine for the right area

Get clear instructions
Confirm where, how often and how long to apply or take the medicine. Treat affected sites as directed rather than only the most itchy patch.
Check safety and tolerance
Discuss allergies, pregnancy or breastfeeding and other medicines before treatment. Report side effects rather than adding another cream yourself.

Topical products represent a clearly explained treatment plan.

STEP 03

Check progress and reduce recurrence

Complete the agreed course
Improved itching does not necessarily mean the infection has cleared. Follow the agreed duration and contact the clinician if symptoms worsen or fail to improve.
Reassess persistent symptoms
A returning rash may involve reinfection, an unsuitable medicine, resistance or a different diagnosis. Further testing or a different plan may be needed.

The raised edge and surface scale are features assessed during follow-up.

Reduce moisture and avoid sharing personal items.

The spaces between the toes are areas to dry carefully after washing.

01
Keep affected areas clean and dry
Dry skin folds and between the toes gently. Change damp clothes and socks, and choose footwear and clothing that let moisture escape.
02
Reduce the spread of ringworm
Do not share towels, combs, bedding or footwear. Wash personal items regularly, clean your hands after touching a rash and wear sandals in communal showers.
03
Check possible sources of reinfection
Tell the clinician if household members have symptoms. A pet with missing fur or a suspected ringworm patch needs veterinary advice. These precautions differ from care for pityriasis versicolor.

Why can a rash keep coming back?

Repeat assessment and testing can help explain a persistent rash.

01
The cause may need another look
Not every recurring rash is fungal. A fresh assessment can check for other skin conditions or more than one problem at the same time.
02
The infection may not be fully treated
Missed applications, stopping early or an untreated affected area can make control harder. Explain any difficulty following the plan without feeling embarrassed.
03
Some fungi resist usual medicines
Drug-resistant ringworm is a recognised problem. A rash that persists despite treatment may need further testing and a different prescription, not repeated unsupervised courses.

Do not self-treat suspected ringworm with a steroid-containing combination cream. If a prescribed cream concerns you, ask the prescriber to review it.

Skin, scalp and nails recover at different speeds.

A nail diagram highlights why the affected nail must grow out over time.

There is no single treatment duration for every fungal infection. Scalp and nail treatment can take longer than treatment for a small skin patch, and a damaged nail needs time to grow out.

Itching and scale may improve before normal colour returns. With pityriasis versicolor, colour differences can remain after the yeast is controlled. Ask the clinician how to judge progress rather than extending medicine just to chase a colour change.

Other causes of an itchy or flaky rash.

Eczema

Eczema can cause dry, itchy patches but needs a different care plan. Avoid assuming every rash needs an antifungal.

Psoriasis

Psoriasis may affect skin, scalp and nails. An examination helps separate it from infection.
