Skin mycosis (fungal skin infection) is a group of diseases caused by different fungi that live on the outer layers of the skin, hair, or nails and can lead to red, scaly, itchy patches or changes in skin color. Most forms are superficial (only on the surface), treatable, and not dangerous, but they can be persistent or spread if not managed correctly.
This is general information. With a scan you'll receive a detailed, personalized analysis — including individual risk assessment, progression tracking and recommended actions.
Skin mycoses are caused by different groups of fungi: dermatophytes (mold‑like fungi that feed on keratin in skin, hair, and nails), Candida (yeast‑like fungi that normally live on the body), and Malassezia (yeast that lives in oily skin areas). Infection develops or flares when conditions favor fungal overgrowth, such as warmth, moisture, skin damage, tight clothing, or a weakened immune system.
You are more likely to develop skin mycosis if you live in a warm, humid climate, sweat a lot, wear tight or non‑breathable clothing or shoes, share towels or footwear, or have conditions like diabetes, obesity, or a weakened immune system. Long‑term antibiotics, steroids, or other immunosuppressive medicines also increase the risk, especially for Candida infections.
Most skin mycoses are treated with topical antifungal medicines (creams, gels, sprays, or shampoos) applied once or twice daily for several weeks, and by keeping the area clean, dry, and well‑ventilated. More extensive, recurrent, or deep infections, or infections in people with weak immunity, may need prescription oral antifungals and medical supervision.
To prevent skin mycoses, keep your skin clean and dry, especially in folds, between the toes, and in the groin; wear breathable shoes and clothing; and avoid sharing towels, shoes, or razors. Managing conditions like diabetes, limiting unnecessary antibiotics or steroids, and promptly treating small fungal spots can also reduce recurrences.
See a doctor if the rash is spreading quickly, very painful, or not improving after 2–3 weeks of proper antifungal treatment, or if you have diabetes, a weak immune system, or fever and feel unwell. For mild, stable rashes, you can use over‑the‑counter antifungals and monitor changes with our AI skin analysis, but seek medical advice if you are unsure of the diagnosis.
Usually not dangerous but can spread or complicate; medical review needed if severe or persistent.

Genital herpes is a sexually transmitted infection caused by herpes simplex virus types 1 or 2. It usually shows up as painful blisters and sores on or around the genitals, anus, or nearby skin. The virus stays in the body for life and can flare up again from time to time. Treatment can’t remove the virus, but it can shorten outbreaks, ease symptoms, and reduce the risk of passing it on.
Herpes simplex is a common viral infection that causes recurring clusters of small, painful blisters on the skin or mucous membranes, most often around the mouth or genitals. The virus stays in the body for life and can reactivate from time to time, especially during stress, illness, or other triggers.
Chickenpox is a highly contagious infection caused by the varicella zoster virus, usually affecting children. It starts with fever and tiredness, followed by an itchy red rash that turns into fluid-filled blisters and then crusts. In healthy kids it usually clears on its own in about 7–10 days, but it can be dangerous for infants, pregnant women, adults, and people with weak immune systems. After chickenpox, the virus stays in the body and can later cause shingles.
Trichomycosis is a fungal infection that affects hair and hair follicles, most often on the scalp (tinea capitis) or in the beard area (tinea barbae). It can cause patches of hair loss, flaking, redness, pustules, and sometimes permanent scarring if not treated in time.
