Lichen sclerosus

Lichen sclerosus is a chronic inflammatory skin condition that most often affects the vulva, causing intense itch, white fragile skin and scarring if untreated. Potent steroid ointment controls it well, and long-term follow-up matters.

Key points

The essentials at a glance.

What to look out for, who treats it, and what usually happens next.

  • Typical symptoms: persistent vulval itch (often worse at night), soreness, white shiny patches, splitting and pain with sex

  • Most common after menopause but can occur at any age, including childhood

  • Untreated, it can scar and change vulval architecture, and carries a small increased risk of vulval cancer

  • Potent topical steroid ointment (usually clobetasol) is highly effective and safe when used as directed

  • Lifelong self-checking and periodic review are advised; any persistent lump, ulcer or non-healing area needs prompt assessment

Understanding it

About Lichen sclerosus.

Lichen sclerosus is thought to be autoimmune, and it targets the delicate skin of the vulva and around the anus, turning it white, thin and fragile. Itching can be maddening, skin splits cause stinging with urine and pain with sex, and over years untreated inflammation can scar, shrinking the labia or tightening the vaginal entrance. It is not an infection and cannot be passed on.

Diagnosis is usually clinical, with a small biopsy where there is doubt. Treatment centres on a potent steroid ointment regimen that settles inflammation and protects the skin's architecture, followed by maintenance dosing, regular emollients and long-term surveillance because of the small associated risk of vulval cancer. In the UK you can start with your GP: on the NHS, a routine referral to a specialist clinic often means waiting 20–45 weeks or more to be seen, while a private consultant will typically see you within around two weeks, with any tests arranged soon after.

Frequently asked

Common questions about Lichen sclerosus.

Quick, plain-English answers to what people ask us most.

  • What is lichen sclerosus?

    Lichen sclerosus is a long-term inflammatory skin condition that most commonly affects the genital and anal area, causing thin, white patches of fragile skin. It's most common after the menopause but can affect anyone at any age.

  • What causes lichen sclerosus?

    The exact cause is unknown, but it's believed to involve the immune system mistakenly attacking the skin, with genetic and hormonal influences likely contributing. It isn't caused by poor hygiene, and it isn't contagious or sexually transmitted.

  • What does lichen sclerosus look like?

    Affected skin typically appears pale, thin, and slightly shiny or crinkled, sometimes described as looking like tissue paper, and may show small areas of bruising or cracking due to fragility. It most commonly affects the vulva in women, but can also affect the penis in men, and rarely other areas of skin.

  • Is lichen sclerosus dangerous?

    It's not immediately dangerous, but if untreated, it can lead to scarring that changes the normal anatomy of the affected area, and carries a small increased risk of skin cancer developing within the affected skin, which is why regular follow-up is recommended. With consistent treatment, these risks are significantly reduced.

  • Is lichen sclerosus hereditary?

    There's some evidence it can run in families, particularly alongside other autoimmune conditions, though most people with lichen sclerosus have no family history of it. Genetic and hormonal factors are both thought to play a role.

  • Can lichen sclerosus be cured or reversed?

    There's no outright cure, but consistent use of potent topical steroid treatment very effectively controls symptoms and prevents the scarring that would otherwise progressively alter the skin. Early treatment gives the best chance of preventing long-term anatomical changes.

  • How is lichen sclerosus treated?

    The main treatment is a strong topical corticosteroid ointment, applied according to a specific regimen initially, then reduced to a maintenance dose to keep symptoms controlled long-term. Gentle skin care, avoiding irritants, and regular specialist follow-up are also important parts of management.

  • How long do I need to use treatment for lichen sclerosus?

    Most people need long-term, often lifelong, maintenance treatment with topical steroids to keep the condition controlled, even after initial symptoms have settled. Stopping treatment completely often leads to symptoms returning, so ongoing use as directed by your specialist is important.

  • Lichen sclerosus vs thrush — what's the difference?

    Thrush is a fungal infection causing itching, soreness and discharge that responds to antifungal treatment, while lichen sclerosus is a chronic inflammatory skin condition causing characteristic pale, thin skin changes that don't improve with antifungal treatment and need specific steroid therapy. The two are sometimes confused initially, but examination usually distinguishes them clearly.

  • When should I see a specialist about lichen sclerosus, and how quickly can I be seen privately?

    Persistent genital itching or skin changes, or symptoms not improving with initial treatments like antifungals, should be assessed by a specialist. Private gynaecology or dermatology consultations can typically be arranged within about two weeks, considerably faster than standard NHS waiting times.
