Lichen Planus in London – Consultant Dermatologist Diagnosis & Treatment
Noticing itchy, purple bumps on the skin, painful mouth patches or nail changes? At Skinhorizon Clinic, lichen planus is assessed and managed by a consultant dermatologist with experience in complex immune-mediated skin disease.
Lichen Planus – At a Glance
What Is Lichen Planus?
Lichen planus is a chronic inflammatory condition that affects the skin, and sometimes the scalp, nails and mucous membranes such as the mouth or genitals.
It is thought to be immune mediated. The immune system targets cells in the outer layer of the skin and mucosa, causing small itchy bumps, colour change or fragile, sore areas. The condition can be limited and mild, or more widespread and uncomfortable.
Lichen planus is not contagious and is not caused by poor hygiene. It often needs specialist assessment to confirm the diagnosis, rule out look-alike conditions and select safe, effective treatment options.
What Are the Symptoms of Lichen Planus?
Symptoms vary depending on where the lichen planus is affecting the body, but several patterns are typical.
- Itchy, flat-topped, purple or reddish bumps on the wrists, ankles or lower back
- Fine white lines or a network pattern on the surface of lesions
- Dark marks where previous lesions have healed, especially in darker skin types
- Scalp involvement leading to scaling or patchy hair loss (lichen planopilaris)
- Nail changes, including ridging, thinning, splitting or nail loss
- White streaks or sore patches in the mouth (oral lichen planus)
- Sore, fragile or white patches in genital areas, sometimes overlapping with lichen sclerosus
Lichen planus can be localised to a small area or involve several body sites at the same time. A full skin, scalp, nail and mucosal review helps to build an accurate overall picture.
What Causes Lichen Planus?
Lichen planus is believed to be an immune-mediated condition. The immune system mistakenly targets cells at the junction between the outer and deeper layers of the skin or mucosa, leading to inflammation and damage.
In some patients, a similar eruption can be triggered by certain medications or by contact with specific substances, such as some dental materials. This is called a “lichenoid reaction” and may resolve when the trigger is addressed.
Other factors that can be relevant include:
- Past or current medical conditions that need to be reviewed
- Skin trauma or scratching (the Koebner phenomenon)
- Possible overlap with other inflammatory or autoimmune conditions
During your assessment at Skinhorizon Clinic, we review your medical history, medications and any potential triggers, and we tailor investigations to your specific pattern of disease.
Is Lichen Planus Serious?
Lichen planus can be very itchy and cosmetically distressing, but in many patients it can be controlled with appropriate treatment and careful follow-up.
Some forms, particularly longstanding mucosal disease (for example oral lichen planus or genital changes overlapping with lichen sclerosus), may carry a small risk of precancerous or cancerous transformation over time. This is why regular specialist review and prompt assessment of any persistent sore or thickened area are important.
Scalp and nail involvement, such as lichen planopilaris, can leave permanent scarring if not recognised and treated early. We therefore pay particular attention to scalp tenderness, hair loss and nail changes during your visit.
How Is Lichen Planus Diagnosed at Skinhorizon Clinic?
Lichen planus is usually diagnosed by an experienced dermatologist using a combination of careful clinical assessment and, where needed, a skin biopsy.
- Consultant examination: your dermatologist will review your history and examine the skin, scalp, nails, mouth and genital areas sensitively and respectfully.
- Dermoscopy: magnified examination of the skin helps to identify patterns typical of lichen planus and rule out other conditions.
- Skin biopsy: a small sample of one or more lesions may be taken and analysed via our diagnostic skin biopsy service to confirm the diagnosis.
- Blood tests: selected blood tests may be arranged through our dermatology-focused blood panels if clinically appropriate.
Where there is scalp, hair or nail involvement, additional evaluation with trichoscopy or nail assessment may be part of your overall work-up.
How Is Lichen Planus Treated?
Treatment for lichen planus aims to reduce inflammation, relieve symptoms and minimise the risk of scarring or long-term damage.
At Skinhorizon Clinic, your personalised treatment plan may include:
- Potent topical steroid creams or ointments applied to active skin lesions
- Topical steroid scalp lotions or foams for scalp involvement
- Specialist topical treatments for mouth or genital involvement, often in partnership with oral lichen planus or lichen sclerosus care
- Short courses of oral steroids or other systemic medicines for more extensive or resistant disease
- Careful skincare advice, including emollients, avoidance of irritants and sun protection where indicated
In more complex cases, additional immunomodulatory medicines may be discussed with you. We always balance potential benefits with safety and monitoring requirements, and we will provide clear written information before starting any stronger treatment.
Your Lichen Planus Journey at Skinhorizon Clinic
We follow a structured, consultant-led pathway so you know what to expect at each stage.
- 1. Initial consultation: a detailed review of your symptoms, history and previous treatments, with a full skin, scalp, nail and mucosal examination.
- 2. Diagnostic plan: dermoscopy, biopsy and blood tests are arranged where appropriate to confirm the diagnosis and rule out mimicking conditions.
- 3. Personalised treatment plan: we agree on a step-by-step regimen for creams, scalp treatments, mouth or genital care and any systemic medicines if needed.
- 4. Symptom control and monitoring: follow-up visits allow us to track progress, optimise treatment and monitor for any potential side effects.
- 5. Long-term support: we focus on maintaining control, protecting areas at risk of scarring and ensuring prompt review if new symptoms appear.
What Results Can You Expect?
Many patients notice improvement in itch, redness and active lesions within a few weeks of starting the right topical or systemic treatment plan.
Pigmentation changes, especially in darker skin tones, may take longer to fade and sometimes leave persistent darker areas where previous lesions have healed. We will discuss realistic expectations for your skin type.
Lichen planus can be a long-term condition, with phases of activity and quiet periods. Our aim is to calm flares quickly, limit scarring or permanent hair and nail damage, and support you with clear guidance for long-term self-management and review.
Lichen Planus – Before and After Treatment
We do not display individual photos on this page, but we document your skin carefully in the clinic so progress over time can be monitored.
Patients may experience intensely itchy, widespread bumps on the wrists, ankles or trunk, with visible colour change and, in some cases, hair or nail involvement.
With tailored management, lesions can become flatter, less itchy and less inflamed, with reduced new activity and stabilisation of hair and nail changes where possible.
Worried About a Possible Lichen Planus Rash?
If you have persistent itchy bumps, mouth changes or nail problems, a consultant dermatologist can help clarify the diagnosis and build a safe, evidence-based treatment plan.

Lichen Planus – Frequently Asked Questions
Is lichen planus contagious?
Lichen planus is not contagious and cannot be passed from person to person through skin contact, sharing towels or everyday activities.
Does lichen planus go away on its own?
Some cases of lichen planus improve over time, but the condition can last for months or years. Treatment helps to control symptoms, limit flares and protect areas at risk of scarring.
Is lichen planus an autoimmune disease?
Lichen planus is considered immune mediated. The immune system reacts against the skin or mucosa, but the exact trigger is not always clear. Your consultant will review your history for any potential contributing factors.
Can lichen planus affect hair and nails?
Yes. Scalp involvement, known as lichen planopilaris, can cause patchy scarring hair loss, and nails may become ridged, thin or split. Early diagnosis and treatment are important to try to prevent permanent change.
When should I seek urgent review for lichen planus?
You should seek urgent assessment if you notice a persistent sore, lump, thickened patch or non-healing ulcer in the mouth or genital area, especially if it changes quickly or bleeds easily.
