Vulvar Lichen Sclerosus: Symptoms, Diagnosis and Treatment
Persistent vulvar itching, pale patches, soreness or skin changes deserve assessment. Learn what lichen sclerosus is, how prescription treatment and follow-up help, and which changes to report.
In this guide
What is vulvar lichen sclerosus?
Lichen sclerosus is a long-term inflammatory skin condition that often affects the skin around the vulva and anus. It can cause itching, pale or white smooth or crinkled patches, soreness, small tears or bleeding after friction. It is not caused by poor hygiene, is not an infection and is not contagious. It can affect people of any age and skin tone.
Notice changes in skin as well as itching
The affected skin may look pale, white, shiny, smooth or crinkled, but appearance varies and can be harder to recognize on different skin tones. It may feel fragile, itch, sting, split or bleed when rubbed. Pain during sex or discomfort when passing urine can occur if the skin becomes tight or sore.
Symptoms can be mistaken for thrush or irritation
Thrush, eczema, contact irritation and other vulvar conditions can cause itching too. Repeated antifungal treatment may not help if the cause is a skin condition. A clinician can examine the area and consider other causes rather than assuming that every itchy vulva is an infection.
The condition is not your fault and cannot be passed to a partner
Lichen sclerosus is not caused by sexual activity, poor cleanliness or a partner. It does not spread through touch or sex. A partner does not need treatment for lichen sclerosus, though intimacy should pause or change if it hurts and you want it to.

Diagnosis and when to seek review
A clinician may be able to recognize lichen sclerosus by examining the skin and hearing how symptoms have changed. Sometimes another test or specialist opinion is needed, especially if the appearance is unclear or an area does not heal. You can ask for a chaperone and for each examination step to be explained.
Arrange an appointment for persistent itch or pale patches
Ask for an assessment if you notice an itchy pale patch on the vulva or around the anus, pain with sex or urination, or symptoms that do not improve with the treatment you were given. Earlier diagnosis can reduce ongoing irritation and lower the chance that scarring goes unnoticed.
Ask whether the diagnosis is clear and whether a biopsy is needed
Many cases are diagnosed from the symptoms and appearance. If the clinician is uncertain, treatment is not working, or a thickened, ulcerated or changing area needs checking, they may discuss a small skin sample or specialist referral. Ask what the test can answer and how you will receive the result.
Report a persistent lump, thickened area or sore
Lichen sclerosus slightly increases the risk of vulvar cancer, though the risk is low. Tell a clinician about a new lump, a thickened or changing patch, or an ulcer or sore that does not heal. This is a reason to have the change assessed, not a reason to assume that it is cancer.
Treatment, comfort and long-term follow-up
Lichen sclerosus cannot currently be cured, but prescribed treatment often controls symptoms and helps protect the skin. A strong steroid ointment is commonly used under medical guidance, often with regular follow-up. Do not use someone else's steroid or change the schedule without asking the clinician who prescribed it.
Use prescription steroid ointment exactly as directed
A clinician may prescribe a potent topical steroid for an initial period and then adjust the plan according to the skin's response. Ask where to apply it, how much to use, how long to continue and what to do if irritation worsens. Correctly prescribed treatment is intended for the affected skin; fear of the word steroid should not lead you to stop without advice.
Reduce friction and irritants if they bother your skin
Unscented gentle skin care, a barrier ointment and loose breathable underwear may reduce irritation for some people. Avoid scratching, fragranced products or anything that stings. These comfort steps support prescribed care but do not replace it or prove whether lichen sclerosus is present.
Keep follow-up even after symptoms improve
Symptoms can improve while the condition still needs monitoring. Ask how often the clinician wants to review you, how to check for new changes and whom to contact if the skin changes. Follow-up can be adapted to your symptoms and access to care; it should not involve an examination without your consent.
Lichen sclerosus: frequently asked questions
Is lichen sclerosus an STI or contagious?
No. NHS guidance says it is not caused by infection, is not contagious and is not caused by poor personal hygiene. A partner does not need treatment for this condition.
Can it be cured?
There is no cure at present, but prescription treatment can control symptoms and help protect the skin. A clinician can explain the initial treatment and any maintenance or follow-up plan.
Can lichen sclerosus lead to cancer?
It is associated with a small increase in vulvar cancer risk. Most people will not develop cancer, but a persistent ulcer, new lump or thickened or changing area should be assessed promptly.
Should I stop treatment when itching improves?
Do not change or stop a prescribed schedule without checking with the clinician. Symptoms can settle before the follow-up plan is complete, and the prescriber can tell you whether to continue, reduce or restart treatment.
Words you can use
Ask about persistent vulvar skin changes
When itching, pale patches, tearing or soreness keeps returning
“I have noticed [itching / a pale patch / soreness / a skin change] since [date]. It affects [sleep, urination, movement or intimacy]. Could you check for lichen sclerosus and other skin conditions? Please explain the examination first, and tell me whether a biopsy, prescription ointment or follow-up would be useful.”
