Lichen Sclerosus in Women: Symptoms, Treatment and UK Support

Lichen sclerosus is a chronic, inflammatory skin condition that primarily affects the genital and anal areas, though it can occasionally appear on other parts of the body. In the UK, it is most frequently diagnosed in women over the age of 50, although it can affect females of any age, including children. The condition causes the skin to become thin, white, and crinkled, often described as having a 'cigarette paper' texture.

According to the British Association of Dermatologists (BAD) and NICE guidelines, lichen sclerosus is not contagious and cannot be spread through sexual contact. While the exact cause remains unknown, it is widely believed to be an autoimmune condition where the body’s immune system mistakenly attacks the skin cells. There is also a known link between lichen sclerosus and other autoimmune disorders, such as thyroid disease or vitiligo.

The symptoms of lichen sclerosus can range from mild to severe. Some women may be asymptomatic initially, with the condition only discovered during a routine cervical screening or pelvic examination. However, most women experience one or more of the following:

• Intense itching (pruritus): Often worse at night, this is the most common and distressing symptom.
• White patches: Small, shiny white spots that can grow into larger, thinned-out patches of skin.
• Skin fragility: The skin may tear easily, leading to painful sores, bleeding, or bruising (purpura).
• Pain and discomfort: This is particularly common during sexual intercourse (dyspareunia) or when passing urine or stools.
• Structural changes: Over time, untreated inflammation can lead to scarring, which may cause the labia minora to shrink or the clitoral hood to fuse.

If you notice any unusual skin changes in the vulval area, it is important to seek medical advice. In the UK, a GP will usually examine the area and may refer you to a gynaecologist or dermatologist for a formal diagnosis. In some cases, a small skin biopsy may be required to confirm the condition and rule out other skin disorders.

First-Line Treatment

The gold-standard treatment for lichen sclerosus in the UK is a very potent topical corticosteroid, such as clobetasol propionate (Dermovate). When used according to a specific tapering schedule, these creams reduce inflammation, stop the itching, and prevent further scarring. Most patients start with a once-daily application for three months, gradually reducing the frequency as symptoms stabilise.

Maintenance and Emollients

Long-term management involves using soap substitutes and emollients to protect the skin barrier. Patients are advised to avoid scented products, bubble baths, and tight-fitting synthetic clothing which can exacerbate irritation.

Discussing genital health can feel daunting, but seeking early advice is essential for managing lichen sclerosus effectively. You should consider booking a consultation with an online doctor in the UK if:

• You have persistent vulval itching that does not respond to over-the-counter thrush treatments.
• You have noticed new white patches or changes in the texture of your genital skin.
• You are experiencing pain during sex or when using the bathroom.
• You have a confirmed diagnosis but your current treatment is no longer controlling your symptoms.
• You need a referral letter or advice on how to access specialist dermatology services.

An online GP can provide a safe, confidential space to discuss your symptoms, offer advice on emollient use, and help you understand the next steps in the diagnostic pathway.

Beyond medical treatment, certain lifestyle adjustments can help manage the discomfort associated with lichen sclerosus:

• Gently pat dry: After washing or using the toilet, pat the area dry with a soft towel rather than rubbing.
• Barrier creams: Applying a plain emollient before swimming or passing urine can protect the skin from irritation.
• Cotton underwear: Wear loose, white cotton underwear to allow the skin to breathe.
• Avoid irritants: Switch to non-biological washing powders and avoid using vaginal deodorants or wipes.
• Silk pillows or cushions: Some women find sitting on a silk or soft foam ring helps reduce pressure on the vulva during flare-ups.

While lichen sclerosus is a lifelong condition, it is usually well-controlled with intermittent steroid use. However, there is a small risk (approximately 3-5%) of developing a type of skin cancer called squamous cell carcinoma (SCC) in the affected area. This is why the NHS recommends that women with lichen sclerosus perform a monthly self-examination and attend annual reviews with their doctor.

If you notice a persistent lump, a sore that does not heal, or a thickened area of skin that feels different from your usual lichen sclerosus patches, you must seek an urgent medical review.
