Vulval Skin Conditions: Symptoms, Identification and UK Treatment

Vulval skin conditions refer to a group of dermatological disorders that affect the vulva—the external part of the female genitals. While many women immediately suspect vaginal thrush or a sexually transmitted infection (STI) when they experience discomfort, many cases are actually due to inflammatory skin conditions. These are not contagious and are often related to the sensitive nature of the skin in this region.

According to the British Association of Dermatologists, the skin of the vulva is more permeable and sensitive than skin elsewhere on the body. This makes it particularly susceptible to irritation from soaps, fabrics, and environmental factors. Common non-infectious conditions include vulval dermatitis (eczema), psoriasis, and general vulval irritation (pruritus vulvae). Understanding the difference between an infection and a skin condition is the first step toward effective relief.

Symptoms of vulval skin conditions can vary depending on the underlying cause, but they often overlap with infectious diseases, leading to frequent misdiagnosis. Patients in the UK commonly report the following:

• Persistent Itching: Often worse at night or after exercise.
• Burning or Stinging: Particularly when passing urine or during sexual intercourse.
• Redness and Swelling: The skin may appear inflamed or brighter than usual.
• Skin Changes: This might include thickened, 'leathery' patches (lichenification) or fine, silvery scales associated with psoriasis.
• Splits or Cracks: Small, painful fissures in the skin folds.

It is important to note that unlike thrush, these conditions do not typically cause a significant change in vaginal discharge. If you have itching without an unusual discharge, a dermatological cause is more likely.

Vulval Dermatitis (Eczema)

This is one of the most common causes of vulval soreness. It can be 'irritant contact dermatitis,' caused by things like scented wet wipes, bubble baths, or tight synthetic clothing. Alternatively, it may be 'allergic contact dermatitis,' a reaction to a specific ingredient in a cream or detergent. The skin usually looks red and may feel dry or flaky.

Vulval Psoriasis

Psoriasis can affect the vulva even if it is not present elsewhere on your body. Because the area is moist, vulval psoriasis often lacks the typical thick silvery scales found on elbows or knees. Instead, it usually appears as well-defined, bright red, shiny patches. It can be very persistent and requires specific management according to NICE clinical guidelines.

Pruritus Vulvae

This is a term used to describe chronic vulval itching where no specific skin disease is immediately visible. It is often a cycle of itching and scratching that damages the skin barrier, leading to further irritation.

Management of vulval skin conditions always begins with a 'vulval care regime' as recommended by NHS trusts across the UK. Minimising irritation is crucial for allowing the skin barrier to heal.

• Wash with water only: Avoid all soaps, bubble baths, and 'feminine hygiene' washes, even those claiming to be pH balanced.
• Use a soap substitute: If you must use a cleanser, use a plain emollient cream (such as aqueous cream or Zerobase) to wash.
• Avoid irritants: Stop using scented liners, wet wipes, and vaginal deodorants.
• Wear breathable fabrics: Choose loose-fitting cotton underwear and avoid tight leggings or jeans for long periods.
• Pat dry: After washing, gently pat the area dry with a soft towel rather than rubbing.

If you have been treating a suspected case of thrush with over-the-counter creams for more than a week without success, it is time to speak to a GP online. Many women feel embarrassed to discuss vulval symptoms, but online consultations provide a discreet, professional environment to address these concerns.

A GP can help differentiate between a fungal infection and a skin condition. During a video or phone consultation, you can describe your symptoms in detail. In the UK, GPs follow NICE CKS (Clinical Knowledge Summaries) to determine if you require a topical steroid, a soap substitute, or an anti-fungal treatment. An online doctor can also issue a private prescription for stronger creams that are not available over the counter, helping you manage the flare-up quickly.

Treatment depends on the specific diagnosis made by a healthcare professional. For inflammatory conditions like dermatitis or psoriasis, NICE guidance typically suggests a tiered approach:

• Emollients: These are moisturising treatments applied directly to the skin to reduce water loss and provide a protective layer. They should be used liberally and frequently.
• Topical Steroids: For active inflammation, a doctor may prescribe a mild to moderate corticosteroid cream or ointment. These are used once or twice daily for a short period (usually 1-2 weeks) to 'calm' the immune response in the skin.
• Antihistamines: If itching is preventing sleep, a non-sedating or mildly sedating antihistamine may be suggested to break the itch-scratch cycle.

If symptoms do not improve with these standard treatments, your GP may refer you to a specialist vulval clinic or a dermatologist for further investigation, such as a skin biopsy.
