Lichen Sclerosus

Lichen sclerosus is a long-term skin condition that usually affects the genital and anal areas. Symptoms can vary, but many people notice small, white patches on the skin that may become larger over time.

A common symptom is intense itching, which can be worse at night. The skin may also become thin and fragile, making it more likely to tear, bleed, or blister easily. This can cause soreness, burning, or discomfort.

Some people experience pain during sexual intercourse, or discomfort when passing stools if the area around the anus is affected. In men, the foreskin may become tight and difficult to pull back.

Over time, the skin may scar or change in appearance. If you notice any of these symptoms, it’s important to have them checked by a Specialist for proper assessment and management.

Lichen sclerosus often starts as small, shiny white spots on the skin. These can grow into larger patches that look thin, pale, and slightly wrinkled, sometimes described as having a “parchment-like” appearance.

The skin may also appear red, swollen, or occasionally bruised. Because it becomes fragile, small cracks or tears can develop.

In more advanced cases, scarring can occur, which may change the shape of the genital area. For example, the foreskin may become tighter in men, or the labia may appear smaller in women. If you notice any unusual skin changes, a Specialist can examine the area and advise on treatment.

Lichen sclerosus can develop at any age, but it is most commonly seen in two groups: women after menopause and children before puberty. It is more common in females, but it can also affect males, often involving the foreskin.

Because the symptoms can look similar to other skin conditions, it’s important to have any persistent changes checked. Early diagnosis helps manage symptoms effectively and prevent complications.

If left untreated, lichen sclerosus can lead to scarring and permanent changes to the genital skin.

In women, this may cause the labia to fuse or the vaginal opening to narrow, which can make sexual intercourse painful. In men, the foreskin may become tight and difficult to retract, sometimes affecting urination or erections.

There is also a small risk of developing a type of skin cancer (squamous cell carcinoma) in the affected area, so regular monitoring is important.

Ongoing symptoms like itching, pain, and discomfort can also affect your quality of life. Early treatment can help control symptoms, reduce scarring, and lower the risk of complications.

The exact cause of lichen sclerosus is not fully understood. However, it is not an infection and cannot be passed to others through sexual contact or skin-to-skin touch.

It is thought to be linked to an overactive immune system, where the body mistakenly attacks healthy skin, causing inflammation and changes in the skin’s appearance. It may also be associated with other autoimmune conditions.

Genetics and hormonal changes may play a role, which is why it is more commonly seen after menopause, although it can affect people of any age. In some cases, it may develop in areas of previous skin damage or scarring.

While the exact cause is unknown, certain factors may increase the likelihood of developing lichen sclerosus.

These include:

• An overactive immune system or existing autoimmune conditions (such as thyroid disorders or vitiligo)
• A family history of the condition
• Hormonal changes, particularly after menopause or before puberty
• Previous skin damage or scarring in the affected area

It’s important to remember that lichen sclerosus is not contagious and cannot be passed on through sex.

Lichen sclerosus can become more severe if it is not diagnosed or treated early. Ongoing inflammation may lead to more noticeable skin changes and scarring over time.

Other factors that can worsen symptoms include:

• Not using prescribed treatments regularly
• Friction or irritation from scratching, tight clothing, or ongoing skin trauma
• Secondary infections, such as thrush or bacterial infections

Hormonal changes and smoking may also affect how the condition behaves. Regular follow-up and sticking to your treatment plan can help keep symptoms under control.

Yes, you can develop lichen sclerosus even if you use a condom. This is because it is not a sexually transmitted infection and is not caused by sexual activity.

Using a condom does not prevent the condition. If you notice symptoms such as itching, white patches, or skin changes, it’s best to have them checked by a Specialist.

No—lichen sclerosus is not something that can be passed from one person to another, so nobody gave it to you.

It is a non-infectious skin condition, most likely related to the immune system, genetics, or hormonal factors. It is also not caused by poor hygiene or lifestyle choices.

There is currently no known way to prevent lichen sclerosus, as the exact cause is not fully understood.

It is not caused by anything you have done, and it is not contagious. The most important step is early diagnosis, which helps manage symptoms and prevent long-term skin changes.

If you notice ongoing itching, soreness, or white patches in the genital area, it’s best to seek medical advice so appropriate treatment can be started early.

Lichen sclerosus is usually diagnosed through a consultation and a physical examination by a Specialist. They will examine the skin for typical signs, such as white, thin, or slightly wrinkled patches.

In many cases, this is enough to make a diagnosis. If there is any uncertainty, a small skin biopsy may be recommended. This involves taking a tiny sample of skin under local anaesthetic and sending it to a laboratory for confirmation.

A correct diagnosis is based on a combination of your symptoms and a physical examination.

Your Specialist will look for typical skin changes and ask about symptoms such as persistent itching or discomfort. Your medical history is also important, especially if you have any autoimmune conditions.

In some cases, a skin biopsy may be needed to confirm the diagnosis and rule out other conditions.

Yes, other conditions can sometimes be mistaken for lichen sclerosus.

Fungal infections like thrush are a common example, as they can also cause itching and discomfort. However, antifungal treatments will not improve lichen sclerosus because it is not an infection.

Other skin conditions such as eczema, psoriasis, or vitiligo can also look similar. If symptoms are ongoing or not improving, it’s important to have a proper assessment to ensure the correct diagnosis and treatment.

If the diagnosis is not clear from an examination, a skin biopsy may be used to confirm it. This involves taking a small sample of skin under local anaesthetic for laboratory testing.

Swabs may also be taken if there is a concern about an underlying infection. A formal assessment is the most reliable way to confirm the diagnosis and start the right treatment.

No, you do not have to tell your partner from a medical point of view. Lichen sclerosus is not contagious and cannot be passed on through sex or physical contact.

However, sharing this information is a personal choice. Some people choose to discuss it with their partner, especially if it affects comfort during intimacy or involves ongoing treatment.

Yes, lichen sclerosus can be managed very effectively, although it is a long-term condition and cannot be permanently cured.

Treatment focuses on relieving symptoms, such as itching and soreness, and preventing scarring. The main treatment is a strong steroid ointment, usually applied regularly at first and then reduced as the skin improves. Many people find their symptoms improve significantly with this approach.

Using gentle moisturisers (emollients) and avoiding irritants can also help protect the skin. Regular follow-up is important to monitor the condition and adjust treatment if needed.

Treatment can greatly improve your comfort by reducing itching, pain, and irritation, which can otherwise affect daily life and sleep.

It also helps prevent scarring and long-term changes to the genital area, which can lead to discomfort during sex or difficulty with normal function. Early treatment helps maintain the normal structure of the skin.

In addition, regular monitoring reduces the risk of complications, including a small risk of skin cancer. Overall, treatment helps protect both your physical health and quality of life.

Lichen sclerosus is usually treated with medication rather than surgery. Most people respond well to steroid ointments, which help control inflammation and symptoms.

Surgery is only considered in certain cases, usually to manage complications. For example, if scarring causes tightening of the skin, a procedure may be needed. In men, circumcision may be recommended if the foreskin becomes too tight.

Yes, there are simple steps you can take to help manage symptoms and protect your skin alongside medical treatment.

These include:

• Using gentle, fragrance-free products or soap substitutes
• Avoiding scented soaps, wipes, or bubble baths
• Wearing loose, breathable cotton underwear
• Applying a plain moisturiser or barrier cream regularly
• Gently patting the area dry instead of rubbing
• Avoiding scratching, as this can worsen symptoms

These measures can improve comfort but should be used together with prescribed treatment.

In most cases, treatment can be started without issue. However, some situations may require a delay or adjustment.

For example, if there is an active infection such as thrush or herpes, this may need to be treated first. If the diagnosis is unclear, further tests or a biopsy may be needed before starting treatment.

Allergies to certain creams and your overall health, including pregnancy or breastfeeding, may also affect which treatments are most suitable. Your Specialist will guide you on the safest and most appropriate option.

Lichen sclerosus is a long-term condition, but with the right treatment, most people are able to manage it well and live comfortably.

Treatment helps control symptoms like itching and soreness, and prevents scarring or skin changes. Many people have long periods where their skin feels normal, although flare-ups can still happen from time to time.

Regular follow-up is important, as untreated lichen sclerosus can lead to permanent skin changes. There is also a small increased risk of skin cancer in the affected area, but this risk is much lower when the condition is properly managed.

No, there is no medical requirement to tell your partner. Lichen sclerosus is not contagious and cannot be passed on through sexual contact.

Sharing this information is a personal choice. Some people choose to discuss it with their partner, especially if it affects comfort during intimacy or ongoing treatment.

Lichen sclerosus does not usually affect your ability to get pregnant or have a healthy pregnancy. Symptoms may even improve or stay stable during pregnancy.

During childbirth, there may be a slightly higher risk of skin tearing if there is scarring, but many people can still have a vaginal delivery. Your maternity team can support you to reduce this risk.

It’s helpful to inform your healthcare team so they can plan your care appropriately.

No, you do not become immune. Lichen sclerosus is a long-term condition, and symptoms can return even after successful treatment.

With proper management, many people have long periods without symptoms, but flare-ups can still occur. Ongoing monitoring helps keep the condition under control.

There is no known way to prevent lichen sclerosus, as the exact cause is not fully understood.

It is not caused by poor hygiene and is not contagious. The most important step is early diagnosis and treatment to manage symptoms and prevent skin changes.

Looking after your skin by avoiding irritants, such as scented products, and wearing breathable clothing can help reduce discomfort if symptoms develop.

No, lichen sclerosus cannot be passed to your baby during pregnancy or childbirth.

It is not an infection and is not contagious, so it cannot be spread to your baby or to a partner. It is thought to be related to the immune system rather than something that can be caught or transmitted.

If you have concerns about your symptoms or comfort during delivery, your healthcare team can support you.

Lichen sclerosus does not usually affect your baby or your ability to have a healthy pregnancy.

However, if there is scarring or narrowing of the vaginal opening, there may be a slightly higher risk of tearing during vaginal delivery. In some cases, your healthcare team may recommend an episiotomy to reduce this risk. Rarely, a caesarean section may be considered if scarring is severe.

It is also common for symptoms to flare up after delivery due to hormonal changes.

Lichen sclerosus is not very common during pregnancy. It is more often diagnosed after menopause, although it can affect people at any age.

If you already have the condition, your symptoms may change during pregnancy. Some people notice improvement, while others may experience flare-ups.

The condition does not usually affect your baby’s development or your delivery options.

Yes, treatment can usually continue during pregnancy and is important to keep symptoms under control.

The main treatment is topical steroid creams, which are considered safe when used as prescribed. These help reduce inflammation and protect the skin.

Your healthcare team may monitor you more closely during pregnancy to ensure your treatment remains suitable.

Lichen sclerosus cannot be prevented, but you can take steps to manage symptoms and protect your skin during pregnancy.

These include:

• Continuing your prescribed treatment
• Using fragrance-free moisturisers and soap substitutes
• Avoiding irritants such as scented products
• Informing your midwife and healthcare team about your condition

Monitoring your symptoms and seeking advice if they change can help reduce discomfort and support a smoother delivery.

Lichen sclerosus can sometimes flare up after childbirth due to hormonal changes, which may cause itching or discomfort.

If you had any tears or stitches during delivery, the skin may feel more sensitive while healing. Using gentle skincare and moisturisers can help support recovery.

The condition does not affect breastfeeding or your baby. Treatments such as topical steroid creams are considered safe to use while breastfeeding when applied as directed.
