Lichen Planus: How to Recognise It, Everyday Skin Care, and When Dermatology Review Is Needed
Lichen planus causes itchy, flat-topped purple or dark patches on the skin and sometimes white patches in the mouth. Learn how it is recognised, what helps day to day, and which signs need a dermatologist.
Key takeaways
- Lichen planus is a non-infectious inflammatory condition that can affect the skin, mouth, nails, scalp, and genitals.
- Skin patches often settle over months to a couple of years, while mouth lichen planus can be longer-lasting and needs regular review.
- A dermatologist should confirm the diagnosis, and mouth sores that do not heal, bleed, or change in appearance need prompt assessment.

Short answer: lichen planus is an inflammatory condition that is not contagious. On the skin it usually appears as itchy, shiny, flat-topped bumps that look purple, brown, or dark grey, often on the wrists, ankles, and lower back. In the mouth it can cause lacy white patches or sore areas. A doctor or dermatologist should confirm the diagnosis, and treatment is usually aimed at easing itch and inflammation while the condition settles.
What is lichen planus?
Lichen planus happens when the immune system reacts against cells in the skin or mucous membranes. The exact trigger is often unknown. In some people similar reactions can be linked to certain medicines or to other health conditions, which is why a doctor may review your medicine list and sometimes suggest blood tests.
Common signs
- Itchy, shiny, flat-topped bumps on the wrists, forearms, ankles, shins, or lower back.
- Patches that look purple on lighter skin and brown, grey, or dark on darker skin tones.
- Fine white lines on the surface of patches.
- Lacy white patches, redness, or painful sores inside the cheeks, gums, or tongue.
- Ridged or thinning nails, or patchy hair loss if the scalp is affected.
Everyday care that helps
- Use a gentle, fragrance-free cleanser and moisturise regularly to reduce dryness and itch.
- Avoid scratching and keep nails short, as injury to the skin can trigger new patches.
- Take lukewarm rather than hot showers and wear loose cotton clothing.
- If the mouth is affected, keep up gentle oral hygiene, visit a dentist regularly, and limit spicy, acidic, or very hot foods if they sting.
- Avoid tobacco and limit alcohol, especially with mouth symptoms.
How doctors treat it
A dermatologist may confirm lichen planus by examination and sometimes a small skin biopsy. Treatment is chosen according to how widespread and uncomfortable the patches are and may include prescription creams, mouth gels, or other medicines. Dark marks can remain after patches settle, especially on darker skin, and usually fade slowly.
When to see a doctor
- A new itchy rash that you have not had diagnosed.
- Mouth sores or white patches that last more than a few weeks, bleed, thicken, or change in appearance.
- Painful genital sores or discomfort passing urine.
- Nail changes or patchy hair loss on the scalp.
- Itch that disturbs sleep despite regular moisturising.
Where homeopathy fits
Some people choose homeopathic products such as Bakson Lichen Aid Drops as optional complementary support alongside dermatological care. They are not a substitute for diagnosis, prescribed treatment, or regular review of mouth lichen planus, and should not replace medicines your doctor has advised.
Long-standing mouth lichen planus needs periodic review by a dentist or doctor. Any mouth ulcer or patch that does not heal, bleeds, or feels hard or lumpy should be checked promptly.
