Vulval Lichen Sclerosus: Symptoms, Causes, and Effective Treatment in the UK

Vulval lichen sclerosus is a chronic inflammatory skin condition that primarily affects the genital and anal areas in women. In the UK, it is most frequently diagnosed in women over the age of 50, although it can occur in girls before puberty and in younger women. The condition causes the skin of the vulva to become thin, white, and crinkled—often described as having a 'cigarette paper' texture.

While the exact cause remains unknown, evidence suggests it is an autoimmune condition where the body’s immune system mistakenly attacks healthy skin cells. It is not caused by an infection, it is not a result of poor hygiene, and it is absolutely not a sexually transmitted infection (STI). According to NICE (National Institute for Health and Care Excellence) guidelines, early intervention is the gold standard for preventing long-term complications such as scarring or architectural changes to the vulva.

Recognising the symptoms of lichen sclerosus is the first step toward effective management. The condition can sometimes be mistaken for persistent thrush or menopause-related dryness, but it has distinct features:

• Intense Itching: Often the most prominent symptom, which may be worse at night and disrupt sleep.
• White Patches: Small white spots that eventually merge into larger, thin, shiny patches.
• Fragile Skin: The skin may tear easily, leading to small red or purple spots (bruising) or open sores.
• Pain and Soreness: This can make daily activities, exercise, or sexual intercourse uncomfortable.
• Anal Involvement: In about 30% of cases, the skin around the anus is also affected, sometimes forming a 'figure of eight' pattern around the vulva and anus.

If left untreated, the inflammation can cause the labia minora (inner lips) to shrink or fuse, and the hood of the clitoris to bury, which can lead to significant physical discomfort and emotional distress.

Because lichen sclerosus shares symptoms with other vulval conditions—such as vulvar eczema, psoriasis, or bacterial vaginosis—a formal diagnosis by a healthcare professional is vital. A GP will typically perform a visual examination of the area. In some cases, if the diagnosis is unclear or the skin does not respond to initial treatment, you may be referred to a gynaecologist or dermatologist for a vulval biopsy.

A biopsy involves taking a tiny sample of the skin under local anaesthetic to be examined under a microscope. While this may sound daunting, it is a routine procedure in the UK that provides a definitive answer and ensures you are receiving the correct treatment for your specific skin type.

The primary goal of treatment is to relieve symptoms and prevent the condition from worsening. According to British Association of Dermatologists (BAD) guidelines, the most effective treatment is a very strong topical corticosteroid cream or ointment, such as clobetasol propionate (Dermovate).

How to apply treatment

• Apply a small 'pea-sized' amount to the affected areas once a day, usually at night.
• Your doctor will likely advise a 'tapering' schedule—for example, daily for three months, then moving to alternate days, and eventually twice a week for maintenance.
• It is important not to stop the cream abruptly without medical advice, as the inflammation may return.

In addition to steroids, using soap substitutes (emollients) instead of scented body washes is highly recommended. Emollients create a protective barrier on the skin, reducing irritation from urine and sweat.

Discussing genital health can be difficult for many patients. Using an online doctor service in the UK provides a discreet, calm, and professional environment to discuss your symptoms. A private online GP can review your history, offer advice on symptom management, and provide private prescriptions for necessary treatments like Dermovate or high-quality emollients.

Furthermore, because lichen sclerosus is a lifelong condition, regular monitoring is required. An online consultation allows for convenient follow-up appointments to discuss how your skin is responding to the steroid regimen without the need to travel to a physical clinic. If your symptoms are severe or unusual, an online GP can also advise on the next steps for a physical referral within the NHS or private sector.

While there is currently no cure for lichen sclerosus, the majority of women find that their symptoms are well-controlled with the correct use of topical steroids. Most patients enter a period of 'remission' where the skin looks and feels much healthier.

It is important to note that there is a small increased risk (approximately 3-5%) of developing vulval squamous cell carcinoma (a type of skin cancer) in areas affected by long-term lichen sclerosus. Therefore, UK health experts recommend performing a monthly self-examination. If you notice any new lumps, ulcers that do not heal, or thickened areas of skin, you must see a doctor immediately for an urgent review.
