Yeast Skin Infection: Care Instructions

Skip Navigation

Your Care Instructions

Yeast normally lives on your skin. Sometimes too much yeast can overgrow in certain areas of the skin and cause an infection. The infection causes red, scaly, moist patches on your skin that may itch.

Common areas for skin yeast infections are skin folds under the breasts or belly area. The warm and moist areas in the skin folds can make it easier for yeast to overgrow. Yeast infections also can be found on other parts of the body such as the groin or armpits.

You will probably get a cream or ointment that contains an antifungal medicine. Examples of these are miconazole and clotrimazole. You put it on your skin to treat the infection. Your doctor may give you a prescription for the cream or ointment. Or you may be able to buy it without a prescription at most drugstores.

If the infection is severe, the doctor will prescribe antifungal pills.

A yeast infection usually goes away after about a week of treatment. But it’s important to use the medicine for as long as your doctor tells you to.

Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It’s also a good idea to know your test results and keep a list of the medicines you take.

How can you care for yourself at home?

  • Be safe with medicines. Take your medicines exactly as prescribed. Call your doctor if you think you are having a problem with your medicine.
  • Keep your skin clean and dry. Your doctor may suggest using powder that contains an antifungal medicine in the skin folds.
  • Wear loose clothing.

When should you call for help?

Call your doctor now or seek immediate medical care if:

  • You have symptoms of infection, such as:
    • Increased pain, swelling, warmth, or redness.
    • Red streaks leading from the area.
    • Pus draining from the area.
    • A fever.

Watch closely for changes in your health, and be sure to contact your doctor if:

  • You do not get better as expected.

What do I need to know about a skin yeast infection?

Yeast is normally present on the skin. Infection happens when you have too much yeast, or when it gets into a cut on your skin. Certain types of mold and fungus can cause a yeast infection. A skin yeast infection can appear anywhere on your skin or nail beds. Skin yeast infections are usually found on warm, moist parts of the body. Examples include between skin folds or under the breasts.

What increases my risk for a skin yeast infection?

  • Elderly age, especially as skin gets thinner and tears more easily
  • Obesity that causes skin folds where moisture can collect
  • Diapers that are not changed regularly and allow moisture to sit on your baby’s skin
  • Diabetes, especially if it is not controlled
  • Bedrest that allows moisture to collect on your skin
  • Immune system problems
  • Certain medicines, including antibiotics or medicines that weaken your immune system
  • Pregnancy or hormone changes
  • Moisture left on your feet or between your toes after you bathe, or that builds up under a ring you wear

What are the signs and symptoms of a skin yeast infection?

Signs and symptoms will depend on the type of yeast causing the infection, and where the infection is located.

  • Red, scaly skin
  • Changes in skin color, especially a beefy red color
  • Itching, dry skin
  • Painful, cracking skin at the corners of your mouth
  • Thick, discolored, chipping nails
  • Skin lesions that may be red or purple and round
  • Pus bumps

How is a skin yeast infection diagnosed and treated?

Your healthcare provider may know you have a skin yeast infection from your signs and symptoms. He or she may take a sample of your skin to check for fungus. He or she may also look at areas of your skin under ultraviolet light to show which type of yeast infection you have. You may be given an antifungal cream or ointment to treat the infection. You may be given antifungal medicine as a pill if your infection is severe.

How do I care for the skin near the infection?

You may only have discolored patches of skin, or areas that are dry and flaking. Care for these skin problems as directed by your healthcare provider. If you have painful skin or an open sore, you will need to protect the skin and prevent damage. You will also need to keep the skin dry as much as possible. Ask your healthcare provider how to care for your skin while the infection clears. The following are general guidelines for caring for painful or open skin:

  • Keep the skin clean. Ask your healthcare provider if you should wash with mild soap and water. Do not use soap that contains alcohol. Alcohol can dry and irritate the skin and make symptoms worse. Your baby’s healthcare provider may tell you to use diaper cream or ointment when you change his or her diaper. This will protect the skin and prevent moisture from collecting.
  • Keep the skin dry. Pat the area dry with a towel. Do not rub, because this may irritate the skin. If you have a skin yeast infection between skin folds, lift the top part gently and hold it while you dry between your skin folds. Always dry your feet completely after you swim or bathe, including between your toes. Dry your skin if you are sweating from exercise or exposure to heat. Use a clean towel each time to prevent spreading or continuing the infection.
  • Keep the skin protected. Ask your healthcare provider if you should cover the area with a bandage or leave it open. Check your skin each day to make sure you do not have new or worsening problems. You may need to have someone check the skin if you cannot see the area easily.

What can I do to prevent a skin yeast infection?

  • Do not share clothing or towels
  • Wear shower shoes if you need to use a public shower
  • Dry your feet completely after you bathe, and apply antifungal powder or cream as directed
  • Put on socks before you get dressed so you do not spread fungus from your feet
  • Wear light clothing that allows air to get to your skin
  • Manage your weight to prevent skin folds where yeast can collect
  • Manage diabetes
  • Use antibiotics correctly to prevent antibiotic resistance
  • Change your baby’s diaper often, and keep the area clean and dry as much as possible
  • Use a diaper cream or ointment that contains zinc oxide or dimethicone on your baby’s diaper area as directed

When should I seek immediate care?

  • You have signs of infection, such as pus, warmth or red streaks coming from the wound, or a fever.

When should I call my doctor?

  • Your symptoms worsen or do not get better within 7 to 10 days.
  • You have new or returning signs of a skin yeast infection after treatment.
  • You have questions or concerns about your condition or care.

Treatment of mycosis in the clinic “Miracle Doctor”: types, forms, prevention

The causative agents of mycosis are microscopic fungal organisms parasitizing in the skin.

There are a huge number of microorganisms on the body, including molds and yeasts. Some of them perform important functions for the body, but some of them, multiplying, can cause serious diseases.

Signs and symptoms of mycosis

  • Itching or burning pain.
  • Cracks in the skin and peeling.
  • Very dry scaly skin.
  • Itching red (or sulfur) patches on the scalp.
  • Wet reddish spots with small red bumps.
  • Reddened areas on the skin with a white spot in the center.
Athlete’s foot, athlete’s groin and ringworm

Mold fungi (dermatophytes) cause epidermophytosis of the foot, groin, as well as ringworm on the skin of the body and head. These fungi live in the dead tissues of the hair, nails and skin surface. Poor hygiene, constantly moist skin and minor skin and nail lesions increase sensitivity to this type of fungal disease.

The first symptoms of inguinal epidermophytosis are itching and rash. This disease, also called “bordered eczema”, affects the groin and anus. Athlete’s foot usually finds itself on the feet, palms and areas between the toes and hands.

Candida albicans

A persistent bright red rash in the diaper area may indicate a yeast fungus, Candida albicans, which appears in a warm, humid environment. Diseases caused by Candida usually develop between skin folds in overweight people. Among the factors that increase the risk of getting sick are pregnancy, obesity, diabetes, cancer, AIDS, human immunodeficiency virus, etc.

Dermatomycosis (mycosis of the skin)

This is a type of yeast infection that manifests itself in a thin, moldy, fungal covering of the skin. The only symptom is slowly growing patches of discolored skin. A common disease among teenagers and young adults.

Dermatomycosis appears more often in children. The characteristic rings may be irregular in shape. They begin at the scalp, but may be lower and grow depending on the severity of the disease, and the infection gradually spreads from the central part of the lesion to the periphery. This infection is highly contagious and is transmitted through shared hats, combs, brushes, and various hairdressing supplies. Carriers of ringworm can be pets.

Diagnosis of mycosis

To diagnose a fungal infection, a doctor only needs to examine the skin. In difficult cases, a laboratory analysis of the cells of the affected area will be required.

Treatment of the fungus is selected depending on the type of mycosis. With epidermophytosis of the feet, inguinal epidermophytosis or ringworm, cosmetic ointments, lotions, special sprays or talc are used. In most cases, this approach is the most effective.

In severe cases or in the chronic course of the infection, the doctor prescribes oral medications.


Diaper rash and irritated skin can be treated with an antifungal cream, provided the affected area is kept dry and clean. Frequent change of diapers or diapers will help with this. For more serious candida infections, your doctor may prescribe oral antifungal medicines. But they should be taken only under the strict supervision of a doctor, because the wrong dosage can cause serious side effects.


Frequent showering will greatly improve the condition. Also use topical medications containing selenium sulfide (selsan, excel) or antifungal creams such as ciclopirox (loprox).

Prevention of athlete’s foot

Athlete’s groin
  • Keep affected areas clean and dry.
  • Do not wear clothing that rubs the skin.
  • If you wear running shoes, keep them clean.
  • Shower and change clothes after exercise.
Athlete’s foot
  • Keep your feet well ventilated, especially between the toes.
  • Only wear socks made from natural materials such as cotton or wool.
  • If you sweat profusely, change your socks and stockings at least twice a day.
  • Wear light shoes made from natural materials that allow the skin to “breathe”.
  • Change your shoes so that each pair is dry with sweat.
  • In public areas such as swimming pools, showers and fitness centers, wear waterproof footwear.
  • Use antifungal talc or spray every day.
  • Do not wear other people’s shoes.

We treat fungal diseases (malacesia) in the veterinary clinic

Veterinary clinic VetOstrov > Services > Dermatology > Fungal diseases of dogs and cats


Malasseziasis (malasseziasis ) is a disease caused by the yeast fungus malassezia dermatitis, which normally can be found in small amounts on the skin and in the external ear canal of the dog and does not require treatment. Malacesia is not infectious to humans and other animals. Skin disease with this fungus occurs when there are disorders in the dog’s body. For example:

  • allergic reactions,
  • hormonal disorders,
  • decrease in immunity.

As a result, the microclimate on the skin changes, and the fungus begins to multiply actively. For malacesia, the most favorable are humidity, heat, inflamed skin in poorly ventilated areas of the body, therefore, the perioral and perianal areas, skin folds, and the external auditory canal are most often affected.

Areas of the body affected by malacesia develop redness or darkening, thickening of the skin, a specific odor and mild to severe itching may appear.

Diagnosis of Malacesiasis

To make a diagnosis, a scraping or swab is taken from the skin or external auditory canal for cytological examination. The diagnosis is confirmed by the detection of a large number of malacesia in the cytology. Since malacesia is normally present on the skin in small amounts, a culture test for malacesia has no diagnostic value.

Treatment of malacesia

Topical or systemic antifungals are prescribed for treatment. In some cases, the treatment is quite long. Since malacesiosis is usually secondary, it is necessary to diagnose and treat the underlying disease.


Candidiasis – a skin infection requiring treatment, the result of the overgrowth of candida fungi, which are normally present in small quantities on the mucous membranes. Its growth occurs as a result of predisposing factors such as:

  • chronic injuries,
  • immunosuppression,
  • long-term use of cytotoxic drugs or broad-spectrum antibiotics.

Candidiasis disease in dogs is rare. Mucosal lesions are characterized by erosions and superficial ulcers, both on the mucous membranes themselves and on the mucocutaneous areas. These can be single or multiple non-healing ulcers covered with a grayish-white coating or plaques.

Skin lesions are characterized by non-healing erosions, erythema, exudation, and crusting of the skin and nail bed.

Diagnosis of candidiasis

Diagnosis is by cytology. Cytology reveals signs of purulent inflammation with numerous yeast fungi, rarely pseudohyphae. A histological examination is also carried out. A culture can be performed by culture, but since candida can normally be present in small quantities on the mucous membranes, a positive culture must be confirmed cytohistologically.

Treatment of candidiasis

Topical or systemic antifungals are used for treatment.

The prognosis for recovery is good, but depends on the cause of the candida growth.

The disease is not contagious to humans and other animals.

Dermatophytosis (lichen)

Dermatophytosis is a fungal disease that is caused by fungi microsporum canis, Microsporum gypseum, Trichophyton mentagrophytes. The superficial layers of the skin, hair and claws are affected. Dermatophytosis is a highly contagious disease. HUMAN CAN BE SICK! Therefore, mandatory treatment and control of the disease is required.

M.canis is the most common. Some animals may be carriers of dermatophytosis without showing clinical signs. Asymptomatic in dogs is rare, sometimes in Yorkshire terriers.

Skin manifestations of dermatophytosis are very diverse. Lesions can be different in number, shape and localization. When affected by dermatophytosis on the body appear single (localized form) or multiple (generalized form) foci, often rounded. It may just be a focus of alopecia, with no signs of inflammation. Sometimes the hair in the focus may appear broken off, or as if trimmed, there may be redness, crusted papules or seborrhea. One of the manifestations of dermatophytosis is folliculitis or furunculosis on the face of an animal, very similar to pyoderma. Sometimes there is a lesion of creon – a nodular formation as a result of an immune response to the introduction of a dermatophyte.

Diagnosis of dermatophytosis

Due to the fact that external manifestations of dermatophytosis are diverse, external examination is not enough to make a diagnosis, additional examination methods are needed. One of the simplest and most inexpensive methods is to use a Woods lamp. Under its light, some types of microspores give a greenish-light green glow on the hair shaft. The next method is hair microscopy – to detect dermatophyte spores. Detection of spores is sufficient to confirm the diagnosis. Also, for the diagnosis, crops are made on special media, followed by microscopy of the grown cultures.

Treatment of dermatophytosis

Tactics of treatment depends on the severity of the disease, age and immune system of the animal, conditions of detention. Sometimes treatment can last several months. Topical and systemic antifungal drugs are used for treatment. Long-haired dogs should be trimmed to facilitate local treatments and to reduce their spread of spores in the environment. There are special vaccines for the treatment and prevention of dermatophytosis.

The disease is highly contagious, all animals in contact should be examined. If there are several animals in the house, then it is best to treat all of them completely with medicated shampoos.
