Fungal Skin Infection vs. Eczema: How To Tell The Difference And Find Relief?


Both fungal skin infections and eczema commonly cause itchy, irritated skin. But their distinguishing characteristics, underlying causes, and most effective treatments differ. Recognizing key differences as part of a professional diagnosis allows proper, targeted treatment to resolve discomfort and achieve healthy skin.

Understanding Fungal Skin Infections  

Fungal skin infections, also termed tinea infections or dermatophytosis, are caused by various fungal species infecting the keratin protein of the skin, hair, or nails.

Fungal Skin Infection

Common fungal skin infections include:

➔  Athlete’s foot (tinea pedis) – Feet, especially between the toes

➔  Jock itch (tinea cruris) – Groin area

➔  Ringworm (tinea corporis) – Body, scalp, face, arms

➔  Nail infections (tinea unguium) – Fingernails or toenails

Getting To Know Eczema

Eczema refers to inflammation of the skin producing red, itchy, cracked, scaly, or oozing rashes. Various types of eczema exist, based on appearance and causes, including:

Atopic dermatitis – Dry, itchy rash from allergies or asthma

Contact dermatitis – Localized rash from contact irritants  

Dyshidrotic eczema – Blisters on palms and soles

Nummular eczema – Circular patches, often from dryness

Seborrheic dermatitis – Red, greasy lesions caused by malassezia yeast

Key Differences Between Fungal Skin Infections And Eczema

CharacteristicFungal Skin InfectionEczema
CauseFungal pathogenInternal inflammation, allergies
LocationWarm, moist areas like feet, groinCan occur anywhere including drier areas
Lesion borderOften defined, raised edgesIndistinct, patchy borders
TimelineStatic, persistentFluctuates in severity
Itch severityTends to be less itchyOften very itchy
ContagiousnessCan spread through contactNot contagious
OdorSometimes have distinct odorsNo odor
TextureDry, scalyOozing, weeping

The key differentiator is the fungal pathogen cause versus intrinsic inflammatory processes. Location, appearance, and contagious potential also help distinguish a fungal infection from eczema.

Paying attention to these nuances guides proper diagnosis and targeted treatment.

Diagnosis And Medical Examination

Doctors diagnose based on:

➔  Visual inspection – Evaluating rash characteristics 

➔ Microscopic exam – Scrapings checked for the presence of fungal hyphae

➔  Cultures – Identifying the particular fungal organism

➔  Allergy testing – Patch testing to identify eczema triggers

Treatment Approaches

Fungal infection – Antifungal topical ointments, oral medication for more severe cases

Eczema – Emollients to moisturize, topical steroids to reduce inflammation, allergen avoidance

Preventive Measures 

Good hygiene – Thoroughly clean and dry infected areas to prevent recurrence and transmission

Manage irritants – Avoid triggers like harsh soaps, and fragrances that can worsen eczema

Protect vulnerable areas – Keep feet dry, wear breathable fabrics, moisturize after bathing

Self-Care And Home Remedies

OTC antifungal creams – Clotrimazole, ketoconazole, terbinafine for fungal infections

Colloidal oatmeal baths – Soothe eczema itch and inflammation 

Cool compresses – For eczema flares to ease inflamed skin

Light therapy – UVB phototherapy helps some eczema cases

When To Seek Professional Help?

Consult a dermatologist promptly if rashes:

➔ Worsen despite home treatment

➔ Spread 

➔ Cause discharge or weeping

➔ Become severely inflamed

➔ Are accompanied by fever  

Prompt diagnosis and prescription treatment can control symptoms, prevent complications like skin infections, and reduce the risks of recurrence in surrounding areas or to other individuals.


Distinguishing fungal skin infections from various eczema types allows proper diagnosis and targeted therapies.

While uncomfortable, understanding the characteristic differences between these common skin conditions guides effective conventional and natural relief options.


1. Can fungal infections trigger eczema flares?

Yes, the fungus can prompt flares in atopic dermatitis. Treating the infection and moisturizing helps control eczema. 

2. Do antifungals work for eczema?

Only if a fungal infection is contributing to eczema flares. Otherwise, they provide no direct eczema symptom relief.

3. Can I use antifungal cream for eczema on my face?

Only if prescribed by your dermatologist. The skin on the face is very sensitive. Most require only gentle moisturizers.

4. What natural remedies help fungal infections?

Tea tree oil, garlic, apple cider vinegar and coconut oil have antimicrobial and antifungal properties. But medical treatment is still recommended.

5. Can fingernail fungal infections spread to the face?

No, dermatophytes that infect nails don’t spread from the hands to the face or body. Different fungal varieties infect other areas.
