Dr. Chrysoula I. Liakou MD, PhD
- Treated online: Yes, usually. Photo and video assessment, prescription when appropriate.
- Most fungal skin infections clear with the right antifungal for the right body site; steroid creams used alone make them worse.
- Antifungal courses typically run one to four weeks and continue beyond visible clearing, because fungus lingers in healed-looking skin.
- Recurrent fungal infections usually have a mechanism: untreated feet or nails reseeding the skin, shared towels, or stopped courses.
- A fungal patch typically has a scaly, slowly spreading edge with clearer skin in the centre.
See a doctor in person instead for scalp infection, above all in children (it needs tablets and usually testing first), for infection spreading despite treatment, or if your immune system is weakened by illness or by medicines such as chemotherapy, biologics or high-dose steroids. Everyday fungal rashes on body, groin, feet and folds are well suited to a photo and video consultation.
Can an online doctor treat a fungal skin infection?
Usually, yes. Fungal skin infections are among the most photo-recognisable conditions, so clear pictures plus a video consultation can often provide enough information to identify the infection and prescribe the right antifungal cream, wash or tablets. Scalp and nail infections are the exceptions that often need in-person testing first, and prescribing rules vary by country.
The umbrella matters here: "fungal infection" covers ringworm on the body, jock itch in the groin, athlete's foot, yeast rashes in skin folds and the patchy discolouration of pityriasis versicolor. They share a cause but differ in treatment, duration and follow-up, which is why the doctor's first job is placing yours precisely on that map.

How an online consultation helps with a fungal skin infection
- The exact infection, named: site plus pattern usually identifies the fungus type from photographs, and that name decides the drug, the format (cream, wash or tablet) and the treatment length.
- Pharmacy or prescription, honestly: many fungal rashes clear with over-the-counter creams used properly. The doctor tells you when that is enough and when prescription treatment genuinely earns its place.
- The steroid trap, caught: steroid creams applied to unrecognised fungal rashes hide the evidence while the infection spreads. If a rash improved then worsened on a cream, that story changes the whole assessment.
- The whole map checked: fungi travel between feet, groin, folds and nails. Treating one site while another reseeds it is the classic reason infections "keep coming back", so the doctor checks all of them.
📷 Photograph the whole affected area in daylight, then a sharp close-up of the edge of the rash, where the diagnosis lives. Add photos of your toe webs (spread your toes) and any odd-looking nails even if your main patch is elsewhere, because the same fungus often travels between sites. Tell the doctor about every cream already applied, especially steroid or combination creams. Our guide to photographing a skin problem for an online doctor shows exactly how.
What the doctor checks in an online fungal skin infection consultation
The assessment is structured around site, pattern and spread. The doctor will typically assess:
- The edge and pattern: an advancing scaly border with central clearing points to ringworm-type infection; uniform redness deep in a fold points to yeast; fine flaky discolouration on the trunk points to versicolor.[1]
- Every likely site: feet and toe webs, groin, body, folds under breasts and abdomen, scalp and nails, because one untreated site quietly reseeds the others.
- Moisture and occlusion: sweat, sport, tight synthetic clothing, boots and hot climates, which fungi love and prevention has to address.
- What has been applied: antifungals used too briefly, and any steroid or combination cream, which can distort the rash into tinea incognito, the disguised form.[2]
- Contacts and sources: affected household members, pets with patchy fur, gyms, contact sports, shared towels and swimming pools.
- Tablet suitability, where relevant: your other medicines and liver health, because oral antifungals interact with several common drugs.[2]
- Background conditions: diabetes, immunosuppression and recent antibiotic courses, which all favour yeast infections in particular.
- Photo quality: daylight, cream-free skin, one wide shot and one sharp close-up per site; on the video call the doctor may ask you to angle the light so scale shows.
Where do fungal skin infections appear?
Fungal skin infections favour warm, damp places, and each site has its own name, look and treatment plan:
- Body and arms (tinea corporis): the classic expanding ring with a scaly border and clearing centre. Our ringworm page covers it in depth.
- Groin (tinea cruris, jock itch): an itchy, sharply bordered rash on the inner thighs and groin folds, common in athletes and hot weather, and usually reseeded by untreated feet.
- Feet (tinea pedis, athlete's foot): itchy peeling between the toes or dry moccasin-pattern scaling on the soles.[3]
- Skin folds (candida intertrigo): raw, glazed redness deep in folds under breasts, under the abdomen or in the armpits, sometimes with small outlying spots; covered on our intertrigo page.
- Trunk colour patches (pityriasis versicolor): fine, flaky patches that look lighter or darker than surrounding skin, most visible after sun, caused by an overgrowth of a normal skin yeast.[4]
- Scalp (tinea capitis): scaly patches, broken hairs and hair loss, mainly in children; always oral treatment and usually in-person testing first.[1]
- Nails (onychomycosis): thickened, crumbly, yellow-brown nails; months of treatment, usually with laboratory confirmation before tablets.
Do I need a prescription antifungal, or will a pharmacy cream do?
Many fungal skin infections clear with over-the-counter antifungals: terbinafine cream typically for 1–2 weeks, or clotrimazole or miconazole for up to 4 weeks, on body, groin or feet, used for the full course and a little beyond visible clearing.[2] Prescription treatment earns its place when patches are large, multiple or on thick skin, when a proper cream course has failed, and for scalp, nail and widespread infections.
Prescription options include stronger topical antifungals, antifungal shampoos used as body washes for versicolor (over-the-counter in some countries, prescription in others), nystatin or imidazole preparations for yeast in folds, and oral tablets such as terbinafine, itraconazole or fluconazole for stubborn, widespread, scalp or nail disease.[2][4] Tablets come with a medicines-interaction and liver check first, and in pregnancy topical treatment is preferred. Two honest notes: antibiotics do nothing against fungi, so they are never part of this treatment; and when a cream "has not worked", the usual explanations are a wrong diagnosis, a course stopped early, or a site that needed tablets from the start.
The steroid-cream warning: tinea incognito
A steroid cream on an unrecognised fungal rash is the most common wrong turn in this whole area. The steroid suppresses redness and itch, so the rash seems to improve for a week or two, while the fungus spreads unopposed underneath. The patch then returns larger, patchier and without its classic border: tinea incognito, the disguised infection that is harder to recognise and slower to clear.[2][5] Never use a steroid or combination cream on an undiagnosed ring or scaly patch. If you already have, do not feel foolish, it is extremely common: just tell the doctor exactly what you applied and for how long, because it changes what they look for and usually lengthens the antifungal course. Combined antifungal-plus-steroid creams have a legitimate but narrow role, calming severe itch briefly and only ever alongside a proper antifungal, never instead of one.
Do home remedies work for fungal skin infections?
Mostly no. Keeping skin clean, dry and ventilated genuinely helps, but popular remedies such as vinegar soaks, garlic, and undiluted tea tree oil have weak evidence and regularly irritate or even burn skin, making the rash harder to diagnose. Antifungal creams are inexpensive, safe and reliable; they are the sensible first step, not the last resort.
Where the do-it-yourself instinct does pay off is prevention: dry thoroughly after washing, especially between toes and inside folds; change out of sweaty clothes promptly; choose breathable fabrics; alternate shoes so they dry; wear flip-flops in shared showers; wash towels hot and stop sharing them; and treat athlete's foot early, because feet are the reservoir that reseeds groin and body infections. If a household member or pet has a scaly patch, treating them at the same time stops the infection circulating.
Which fungal infection treatment might the doctor recommend?
Treatment follows the body site and the story. This is the framework our doctors use, aligned with the cited guidance:[2][3][4]

| Presentation | Likely first step | Suitable for online care? | When referral or in-person care is needed |
|---|---|---|---|
| Classic ring on body or groin | Topical antifungal: terbinafine 1–2 weeks, or clotrimazole or miconazole up to 4 weeks | Usually yes | Not clearing after two weeks of correct use, or the diagnosis is unclear |
| Itchy peeling toe webs or scaly soles | Topical antifungal plus a drying routine; oral treatment for moccasin-pattern or recurrent disease | Usually yes | Broken, hot or spreading skin; and any foot infection with diabetes needs same-day in-person care |
| Raw red rash deep in a skin fold | Antifungal for yeast, with drying and barrier measures; briefly combined with a mild steroid if very itchy | Usually yes | Weeping, very painful or repeatedly relapsing folds, or diabetes needing wider review |
| Flaky lighter or darker patches on trunk (versicolor) | Antifungal shampoo used as a wash, or topical antifungal; tablets for extensive recurrence | Usually yes | Extensive or repeatedly recurring disease, per local pathways |
| Scalp or nails involved | Oral treatment; scalp cases (mainly children) and nails usually need laboratory confirmation first | Assessment online; treatment often starts in person | Always for children's scalp infection; kerion (boggy tender scalp swelling) the same day |
Availability of individual medicines and who may prescribe them vary by country; your doctor confirms what applies where you are.

See available times →How long does treatment take, and why do infections come back?
Skin infections on body, groin and feet usually improve within one to two weeks of correct treatment, but the full course matters: often 1–4 weeks depending on the product, continued a little beyond the point the skin looks normal, because fungus lingers in skin that looks healed.[2] Versicolor has an extra honesty note: the fungus clears in weeks, but the pale or dark patches take months to blend back as pigment recovers, and that slow colour correction is not treatment failure.[4] Nails are the marathon: months of treatment and slow regrowth.
Recurrence almost always has a mechanism rather than bad luck: a course stopped early, feet or nails left untreated while the groin was treated, shoes and towels reseeding the skin, a pet or family member with an untreated patch, or heat, sweat and occlusion never addressed. Fixing the loop is part of the consultation, not an afterthought. If a rash keeps failing sensible treatment, the diagnosis deserves rethinking: discoid eczema and psoriasis both mimic fungal patches, and skin scrapings in person settle stubborn uncertainty.
When we treat a fungal skin infection online, and when we refer you
We treat online: body and groin ringworm; athlete's foot, including recurrent cycles; yeast rashes in skin folds; pityriasis versicolor; suspected tinea incognito after steroid creams, where the history makes the diagnosis; tablet courses for suitable stubborn cases after a medicines check; and reviews when treatment is not clearing on schedule.
We refer or redirect you: scalp infection, above all in children, for oral treatment and usually testing in person; a kerion, the same day; nail infections where local pathways require confirmation before months of tablets; infection spreading despite treatment, or in anyone immunocompromised; foot infections in people with diabetes, in person the same day; and any rash where the diagnosis stays uncertain after photo and video review, where skin scrapings give the answer. In those cases the consultation buys you a precise next step, not another cream.
When to get in-person care
Fungal skin infections are rarely dangerous. Get prompt in-person care for a kerion (a boggy, tender scalp swelling), for infection spreading fast despite treatment, for any significant skin infection if you are immunocompromised or have diabetes, or if broken infected skin becomes hot, swollen and rapidly redder. If that comes with high fever, confusion or rapid breathing, call 112 immediately.
Treating fungal skin infections at home: what helps and what does not
For most fungal skin infections, including athlete’s foot and ringworm of the body or groin, home treatment is genuinely right: pharmacy antifungal creams used for the full course even after the rash fades, careful drying especially between the toes, and not sharing towels.
What home care cannot do: creams cannot cure fungal nails or scalp infections, which need prescription oral antifungals to reach the problem, and they cannot help when the diagnosis is wrong, because eczema and psoriasis imitate fungus convincingly. An infection that is spreading, returning or unmoved after four weeks of proper cream deserves a doctor’s eye.
The strongest at-home treatment is still a doctor. A video consultation brings one to your sofa, usually within about 15 minutes: an honest assessment, and a prescription to a local pharmacy when treatment is right. Book a video consultation: the exact price is shown before you pay.

Frequently asked questions about fungal skin infections
Can an online doctor prescribe antifungal treatment in Europe?
Yes, after a consultation. A prescription is never issued without one: the doctor identifies the infection from your photos and history by video first, then prescribes the antifungal cream, wash or tablets that fit. You get a prescription you can use at a pharmacy near you in most EU countries, and your doctor confirms what applies in your country. Scalp and nail infections often need in-person testing before oral treatment starts.
How much does a fungal skin infection consultation cost?
The exact price of a video consultation is shown before payment, and there is no subscription. If the doctor can’t treat you online, you get a full refund and clear directions to the right care.
How quickly can a doctor look at my rash?
Appointments are available daily from 7am to 11pm, often within about 15 minutes. Fungal rashes are among the most photo-recognisable skin problems, so one consultation with clear pictures is usually enough for a diagnosis and a treatment plan.
Do home remedies like vinegar or tea tree oil cure fungal infections?
The evidence is weak, and irritation is common: vinegar, garlic and undiluted tea tree oil can inflame or burn skin and make the rash harder to diagnose. Keeping skin clean and dry genuinely helps, but the reliable treatment is an antifungal cream used for the full course, with prescription options when that is not enough.
Why does my fungal infection keep coming back?
Usually a loop is running: treatment stopped as soon as the itch faded, untreated athlete’s foot or fungal nails reseeding the skin, damp shoes and shared towels, or a family member or pet with an untreated patch. Break every link at once: full-length treatment, drying routines, hot-washed towels, and checking feet, nails and contacts.
I used a steroid cream and the rash got worse. Why?
Steroid creams calm redness and itch while letting fungus spread, so the rash improves briefly, then returns larger and odd-looking, a pattern called tinea incognito. It remains very treatable: tell the doctor exactly what you applied and for how long, expect a somewhat longer antifungal course, and avoid steroid creams on undiagnosed rashes in future.
Are fungal skin infections contagious?
Mildly, yes. They spread through skin contact and shared towels, bedding, sports mats and changing-room floors, and some come from pets. Once effective treatment starts, the risk drops quickly and normal work, school and sport are generally fine: keep the area covered where practical and stop sharing towels.
How long until my skin colour evens out after pityriasis versicolor?
Often months. Antifungal treatment kills the yeast within weeks, but the lighter or darker patches fade only as pigment production recovers, and sun exposure makes the contrast more obvious in the meantime. Persisting colour change after treatment is expected, not failure; new scaly patches are the sign that treatment is actually needed again.
