Lichen Sclerosus Overview

Lichen Sclerosus can be scary, but the more information and education people have, the better they can manage this condition.

Written by Kathy Ruiz-Carter

Edited by Dr. Jill Krapf

What is Lichen Sclerosus (LS)?

Lichen sclerosus (LS) is a chronic, inflammatory skin condition. It can lead to skin changes, painful sex, and, in rare cases, vulvar cancer.

According to research, “one in 70 women presenting to a general gynecology practice with practitioners experienced in diagnosing this condition”1

have Lichen Sclerosus. Around one-third of these people will not feel symptoms but may have structural skin changes.

Biopsy-proven diagnoses of Lichen Sclerosus almost doubled between 1991 and 2011.2 Researchers believe this is due to increased awareness and not increased disease.3

This is great news and gives us hope for the future. Awareness and education of patients and practitioners are important to prevent the unknown progression of this disease.

Who can get Lichen Sclerosus (LS)?

While anyone can have LS, current research shows that prepubescent and post-menopausal vulva owners are the most affected. This research is misleading as “up to 40% of women with LS will display onset of symptoms and cutaneous (skin) changes of vulvar LS during their reproductive years”.4 We believe this often leads to reproductive-aged vulva owners being mis- and undiagnosed.

Some researchers believe symptoms present differently depending on age group. 3 This difference could be another factor in vulva owners waiting an average of 5-15 years from the onset of symptoms to be properly diagnosed.4,5

Prepubescent and post-menopausal vulva owners' main symptoms tend to be vulvar itching. In contrast, people of reproductive-aged years mostly complain of painful sex. We need more studies to determine the cause of this anomaly. Although some researchers theorize it is hormonal and has to do with estrogen levels.

What causes Lichen Sclerosus (LS)?

Although there is currently no cure for LS, we are closer to finding the cause. We know there is a protein that lives on the basement layer of the skin.

For an unknown reason, the body does not recognize this protein as itself, therefore causing the immune system to attack and create large amounts of localized inflammation. The buildup of this inflammation thickens and hardens the skin, causing Lichen Sclerosus's progressive symptoms.


This process leads some researchers to believe Lichen Sclerosus is an autoimmune condition. In addition, it mostly affects vulva owners and is often accompanied by other autoimmune disorders, which follow the pattern of other autoimmune diseases.

A retrospective study published in 2013 showed that 20-35% of the vulva owners surveyed had a second autoimmune disease. It showed the chances of thyroid diseases, such as Hashimoto thyroiditis or Graves' disease, were at least 4 times greater than any other additional condition.

Other autoimmune conditions were:

  • Vitiligo (loss of skin color in patches)
  • Alopecia areata (patchy hair loss, often in clumps the size and shape of a quarter)
  • Psoriasis (red, itchy, scaly patches, most commonly on the knees, elbows, trunk, and scalp)
  • Inflammatory bowel disease (e.g., Crohn's disease, ulcerative colitis)
  • Rheumatoid arthritis (inflammation and pain in the joints)
  • Pernicious anemia (decrease in red blood cells that occurs when the intestines cannot properly absorb vitamin B12)

This study found that “females diagnosed with LS should be screened for other autoimmune diseases, particularly for thyroid disease.”6

However, the 2018 British Association of Dermatologists guidelines for managing LS do not support routine screening for other autoimmune conditions at this time.


Some researchers also believe there is a genetic component to Lichen Sclerosus. Researchers questioned over one thousand females with vulvar Lichen Sclerosus on their family health history. It showed 12% of the participants had a first-generation relative with LS. This, along with the discovery of genes associated with Lichen Sclerosus, led researchers to suspect there is a genetic component to Lichen Sclerosus.7


Because of the prevalence of diagnosis in prepubescent and post-menopausal vulva owners, low estrogen levels could be a factor in triggering Lichen Sclerosus.8

Atrophy caused by low estrogen often accompanies an LS diagnosis. Thus, medical providers often prescribe topical estrogen to regain elasticity in the skin.

We need more research on hormones and Lichen Sclerosus to understand their true effect better.


Many vulva owners report symptoms after suffering trauma to the vulva skin. Traumas such as childbirth, pelvic surgery involving the vulva, bike accidents, and horseback riding.8

It's unknown how trauma factors into LS. Again, we need more research.

Multiple Factors

It is likely multiple factors play a role in developing LS. The most important thing is to get a diagnosis and begin proper treatment.

Lichen Sclerosus Symptoms

Common Symptoms

Severe Symptoms:

Secondary Symptoms:

  • Itching (mostly at night)
  • Burning
  • Pain/soreness
  • White waxy skin or patches
  • Fissures, ulcers, nonhealing legions, or blood blisters
  • Tearing of the skin
  • Chronic urinary tract or yeast infections (including yeast or bacterial infections on the outside skin of the vulva)
  • Labial resorption (tightening of the skin or loss of skin folds)
  • Clitoral phimosis (fusing of the clitorial hood)
  • Labial scarring/fusing (connections around the opening of the vagina leading to narrowing or tearing)
  • Depression
  • Isolation
  • Fatigue
  • Anxiety
  • Low self-esteem
  • Loss of sleep
  • Low libido
  • Loss of relationships
  • Pain during sex, urinating, or having a bowel movement
  • Vulvar cancer

Lichen Sclerosus presents differently for everyone. Consequently, these symptoms are what doctors look for when diagnosing, thus making it difficult for the untrained eye.

Patients can have one or a variety of common symptoms, for example, itching, white skin patches, and/or burning. Some patients are asymptomatic and don't realize they have LS until they start experiencing painful sex or problems urinating. Others, who have often gone untreated, develop severe symptoms such as fusing/scarring or, less commonly, vulvar precancer or cancer.3

Lichen Sclerosus affects mental health.

Unfortunately, most will suffer from secondary symptoms the hardest. The mental health issues related to a Lichen Sclerosus diagnosis can run deep. That's why referral for counseling should ideally accompany every diagnosis.9

The scariest part is patients may not realize they are suffering or need help, which affects their relationships, work, and general quality of life.

While all Lichen Sclerosus symptoms are difficult, mental health issues can cause the most harm. Most patients suffer alone. So they cycle in and out of loneliness, anxiety, and depression, not realizing they need help. This vicious cycle is why having a support system, whether a counselor, therapist, or support group, is important. Patients must have a place to connect. Check out our resources page for virtual support groups.

How is Lichen Sclerosus (LS) Diagnosed?

Doctors can often diagnose patients with classic Lichen Sclerosus physical symptoms by sight. These include but are not limited to waxy paper skin texture (typically in a figure-eight pattern around the labia minora and anus), scarring/fusing of the clitoral hood, vaginal opening, or labia, or resorption of the labia minora.

However, doctors should use a biopsy to diagnose Lichen Sclerosus if

  • The physician is unsure of the diagnosis.
  • The patient does not have typical symptoms.
  • Treatment is not working.
  • There is a concern about precancers or cancer.

A biopsy should be done before steroid treatment begins because steroids change the skin's texture, possibly causing false-negative results.10 Biopsies should be taken where there is active LS and sent to a pathologist knowledgeable about vulvar inflammatory skin conditions. It is also helpful for the physician to indicate what conditions they are trying to rule in or out.

It is not uncommon for biopsies to come back as “unsure” or negative due to the previously discussed factors. Early LS biopsies have come back as eczema or “nonspecific vulvitis” because they do not show the large levels of inflammation as advanced LS.11

While an optimal biopsy can diagnose LS, an inconclusive biopsy may not rule out LS completely. A specialist in vulvar skin conditions will use the history, physical exam, and biopsy to diagnose LS and develop a treatment plan.


Scientists have studied treatments for Lichen Sclerosus for decades. New ones pop up every so often. Unfortunately, physicians adopt them before they are proven effective due to the lack of solid research and patients' demand for more options.

Ultra-potent steroids are the one treatment that has consistently come out on top. Consequently, they are considered the gold-standard treatment for LS.

Steroids as a Treatment for Lichen Sclerosus (LS)?

Researchers have studied steroids as a treatment for Lichen Sclerosus for over 50 years. They continuously come out on top as the most effective treatment for most people.

This is because of what steroids do; they reduce inflammation. The inflammation causes Lichen Sclerosus symptoms. Treatments must reduce inflammation until the skin regains its normal texture to reach remission.

Unfortunately, there is a lot of misinformation about topical steroid treatment for LS. Myths such as topical steroids:

  • Thin the skin.
  • Get into the bloodstream and causes glaucoma, migraines, and other side effects.
  • Suppress the immune system.
  • Affect your adrenal system.
  • Cause scarring/fusing.

These myths have been busted.12 They are not true. On the contrary, steroids have been proven safe and effective over long-term use.13

How to apply steroids for optimal treatment of Lichen Sclerosus (LS).

The critical part of topical steroid use in treating Lichen Sclerosus is ensuring the patient is applying their steroids optimally. Both the schedule of steroid application and how it is applied to the genitals are crucial for success.

For optimal delivery of the topical steroid, it is important to: 3

  • Soak for 15-20 minutes in warm water before applying the steroid. Patients can use a tub, sitz bath, litter box, kiddie pool, or shower for soaking. Soaking softens the skin and opens the pores, enabling the steroid to penetrate deeper, closer to the bottom layer of the skin, targeting the deepest inflammation. It's important to pat dry after soaking, before applying the steroid, to remove any water that could prohibit the steroid from being absorbed.
  • Use an ointment versus a cream. Ointments are more potent and last longer. Furthermore, many creams contain alcohol. For those with tears or fissures, this can cause additional burning, deterring many from continual steroid use.
  • Rub the ointment in for 90-120 seconds. Due to the high levels of inflammation LS causes, soaking alone is often insufficient in allowing the steroid to penetrate deep enough. Extensive rubbing pushes the medication deeper into the skin, making it more likely to reach its target.
  • Use between a fingertip and half a pea-sized amount. Work your way down to the minimum you need without symptoms returning. Using the minimal amount will ensure overuse of the product does not occur.

How often to apply ultra-potent topical steroids to treat Lichen Sclerosus (LS).

Steroid schedule guidelines vary from country to country, as well as by steroid potency. Unfortunately, these inconsistencies confuse patients and practitioners, making it hard to know which treatment plan is accurate.

It's important physicians learn the guidelines and then develop treatment plans tailored to each patient's unique case. Not only should they create individualized treatment plans, but they also need to explain them to the patients so they become partners in their care.

The following are general application guidelines in the United States for ultra-potent topical steroids, but again, they vary even among individual doctors.

  • Once a day, every day for one month.
  • Then once every other day for one month.
  • Then, twice a week for life to stop your symptoms from returning. Twice a week is considered maintenance.
  • If symptoms return, begin the schedule over again.

Second-line Lichen Sclerosus (LS) treatment.

Topical calcineurin inhibitors are second-line treatments for Lichen Sclerosus. They also reduce inflammation but work in a different way than steroids.

When studied against steroids, TCIs took longer to have the same effect as steroids and had a higher occurrence of vulvar cancer. Thus making them second to steroids but a good option for people who do not want or can not tolerate steroids.14

Experimental Treatments

Recently, a couple of new treatment options have been growing in popularity. These treatments include platelet-rich plasma injections and Co2 fractional laser. However, current research lacks enough evidence showing these treatments reduce the inflammation caused by Lichen Sclerosus, therefore controlling the condition.

Double-blind placebo trials have proven platelet-rich plasma (PRP) and Co2 Fractional Laser ineffective. However, we need more research and larger clinical trials to truly rule them or possible effective combinations out.15,16,8

Day-to-day Care

The following is a list of complementary treatments and care options patients may consider adding to their routine to manage their Lichen Sclerosus and related symptoms found in the eBook, “Lichen Sclerosus Fundamentals: Information for Newly Diagnosed Folks, LS Patients, Caregivers, and Healthcare Providers” by Jaclyn Lanthier.

Pelvic Floor Physical Therapy:

Although pelvic floor physical therapy doesn't treat Lichen Sclerosus, it does treat possible secondary symptoms, such as

  • chronically tight pelvic floor muscles
  • painful sex
  • urinary issues such as urgency, burning, and discomfort
  • bowel issues such as constipation

A pelvic floor physical therapist (also known as a pelvic floor physiotherapist/PFPT) can also work on loosening the scar and fibrotic tissue caused by LS. PFPTs use gentle stretching and bring more blood flow to the area, causing the skin to be more elastic. Learn more at lssupport.net/pfpt.


Emollients/moisturizers are recommended by specialists, as topical steroid treatments can reduce moisture in the skin. They help protect, moisturize, soften, and relubricate the skin.

Furthermore, they help reduce friction, which can cause irritation and result in a flare. When used with a treatment plan that addresses the inflammation caused by Lichen Sclerosus, emollients/moisturizers can help prevent the skin from sticking together and fusing. 

Barrier creams

Barrier creams are thicker than emollients and moisturizers. Some examples are Vaseline or Aquaphor. They create a barrier between the vulvar skin and things it comes in contact with, such as urine, water, underwear, clothing, etc.

This barrier can be especially helpful if patients have fissures or tears. For example, urine can burn and sting breaks in the skin, but using a barrier cream over open wounds can reduce pain, protect the skin, and promote healing. 

Therapy and counseling

As mentioned above, Lichen Sclerosus is just as hard, if not harder, on patients' mental health than their physical health. Most doctors do not refer patients for counseling. Still, it can be extremely beneficial to work through depression, fear, health anxiety, sexual health, loss of sexual identity, and anything else that may come up from Lichen Sclerosus. 

Topical estrogen and testosterone creams

Although they do not impact inflammation, topical estrogen and testosterone creams can improve skin health. They are to complement a Lichen Sclerosus treatment plan.

Hormone creams help reverse dryness and atrophy. They also help plump the skin back up. There are many different types of application options that can be used internally in the vagina and externally on the vulva.

Stress management

Stress can be a huge trigger for many with Lichen Sclerosus. Exploring different de-stressing techniques can help patients achieve remission faster and remain in remission longer.

Practicing mindfulness and meditation practices, shaking and dancing, exercise, yoga, baking, essential oils, listening to music, and painting/drawing are all ways to manage stress. 

Diet & Nutrition

Some people with Lichen Sclerosus feel diet/food is their biggest LS trigger. It may be beneficial to talk to a registered dietician or nutrition therapist to test for food sensitivities, allergies, etc. Some have found benefits following a low oxalate diet; others have found benefits following the autoimmune protocol.

There are currently only two studies explicitly focused on diet and Lichen Sclerosus. Both have issues, and their results are inconclusive. Thus, it can be helpful to have a nutrition therapist or dietician help patients navigate different diet options. 

Naturopath or functional medicine doctor

Naturopath or functional medicine doctors work with patients to figure out their symptoms' root cause(s). They may suggest food sensitivity testing, GI MAP testing, etc. Once they establish root causes, they work with patients on diet, lifestyle, supplements, etc., to address their Lichen Sclerosus condition.


Lichen Sclerosus is a complex and aggressive condition. Its effects are mental and physical. Due to the lack of awareness by both patients and practitioners, many people suffer in isolation, depression, anxiety, and more unknowingly.
