Vitiligo Overview

Vitiligo causes patches of skin to lose their color. Additionally, it can also affect the eyes and hair. Furthermore, people of any age, sex, and ethnicity can develop it. Notably, vitiligo patches are more sensitive to sunlight. Moreover, melanocytes are the cells responsible for producing melanin. Specifically, melanin gives skin its color and protects it from the sun’s ultraviolet (UV) rays.

Facts on vitiligo

Here are some key points about vitiligo:

  • First, vitiligo can affect people of any age, sex, and ethnicity.
  • Second, there is no cure, and it is usually a lifelong condition.
  • Third, vitiligo is an autoimmune disease.
  • In addition, vitiligo is not contagious.
  • Finally, treatment options may include exposure to special UV light wavelengths and medications to restore color and slow the development of new depigmented patches.

What is Vitiligo?

Vitiligo is a skin condition in which patches of skin lose their color. Furthermore, the total area of skin that vitiligo affects varies between individuals. In addition, it can also affect the eyes, the inside of the mouth, and the hair. In some cases, affected areas may remain discolored for the rest of the person’s life; however, others may experience spontaneous re-pigmentation. Moreover, the condition is photosensitive. This means, consequently, affected areas are more sensitive to sunlight than unaffected areas. Additionally, it is hard to predict whether the patches will spread and how much. Specifically, the spread might take weeks, or on the other hand, the patches may remain stable for months or years.
Finally, lighter patches tend to be more visible in people with darker skin tones.

Symptoms of Vitiligo

The characteristic symptom of vitiligo is, specifically, the appearance of flat lighter-colored spots or patches on the skin. Initially, the first white spot that becomes noticeable is often an area of a sunburn or minor injury. Furthermore, it may start as a simple spot, a little paler than the rest of the skin; however, as time passes, it becomes paler until it eventually turns white. Moreover, the patches vary in shape and size. In some cases, the edges can sometimes be inflamed, which sometimes results in itchiness. Typically, however, it does not cause any discomfort, irritation, soreness, or dryness in the skin. Nevertheless, it is typically more prone to sunburn. Additionally, the effects of vitiligo vary between people. For example, some people may have only a handful of white dots that develop no further, while, on the other hand, others develop larger white patches that join together and affect more significant areas of skin. Finally, some people may also experience hearing loss, loss of eye pigmentation, and other autoimmune diseases, such as thyroid disease.

Causes and Risk Factors of Vitiligo

What causes vitiligo is unknown; however, there are a few theories. Some possible causes include: 1. Genetics: For instance, an estimated 20% of people with vitiligo have a first-degree relative with the condition. 2. Autoimmune response: In this case, the body’s immune system attacks and kills melanocytes. 3. Oxidative stress: Specifically, when people have an imbalance of oxygen molecules and antioxidants, it may lead to vitiligo. 4. Environmental factors: Moreover, emotional distress, sunburn, or chemical exposure may lead to vitiligo.
What causes vitiligo is unknown. However, there are a few theories.
Some possible causes include:
  • Genetics: For instance, an estimated 20% of people with vitiligo have a first degree relative with the condition.
  • Autoimmune response: In this case, the body’s immune system attacks and kill melanocytes.
  • Oxidative stress: Specifically, when people have an imbalance of oxygen molecules and antioxidants, it may lead to vitiligo.
  • Environmental factors: Moreover, emotional distress, sunburn, or chemical exposure may lead to vitiligo.
Consequently, a person has a greater chance of getting vitiligo if they have a family history of the condition. Nevertheless, certain autoimmune diseases are linked to an increased risk. About 15–25% of people with vitiligo have another autoimmune condition.
These other autoimmune conditions include:

Complications

Vitiligo may not develop into other diseases, but people with the condition are more likely to experience:
  • Changes to vision and tear production, such as iritis
  • Hearing loss
  • Increased risk of skin cancer
  • Painful sunburn
  • Social stigmatization and mental stress
Most people with vitiligo do not have these conditions, but a doctor may do tests to rule them out.

Overcoming social challenges

If the skin patches are visible, the social stigma of vitiligo can make it more challenging to cope. Embarrassment can lead to problems with self-esteem, and in some cases, anxiety and depression can result.
Increasing awareness about vitiligo, such as by talking with friends about it and seeking role models with vitiligo, can help people with the condition overcome these difficulties. Connecting with others who have vitiligo may also help.
Anyone with this condition who experiences symptoms of anxiety and depression can ask their dermatologist to recommend a mental health professional.

Diagnosis of Vitiligo

Any person can develop vitiligo at any age. However, it usually appears between ages 20 and 30 years. It can also occur in early childhood.
When a person seeks medical treatment, a doctor typically asks about family history and performs a physical exam, especially on the skin.
A doctor may also use a black light, an ultraviolet light shined on the skin, to help identify depigmented skin that appears chalky under the light.

Treatment of Vitiligo

The American Academy of Dermatology describes vitiligo as “more than a cosmetic problem.” It is a health issue that needs medical attention.

Several remedies can help decrease the visibility of the condition, though some people may not want to treat the condition at all.

Using sunscreen

The American Academy of Dermatology recommends using sunscreen to protect the skin. The lighter patches of skin are especially sensitive to sunlight, and they can burn quickly. A dermatologist can advise on a suitable type of sunscreen.

Phototherapy with UVB light

common treatment option is exposure to certain wavelengths of ultraviolet B (UVB) light, called phototherapy. Home phototherapy units are available but must be used with the supervision of a physician.

If a person goes to a clinic for treatment, a healthcare professional may recommend two to three visits per week.

If there are white spots across large body areas, UVB phototherapy may help. It involves full-body treatment in an office setting.

UVB phototherapy, combined with other treatments, can positively affect vitiligo. However, the result is not predictable, and there is still no treatment to fully re-pigment the skin.

Phototherapy with UVA light

Done in a healthcare setting, UVA treatment involves people taking a drug that increases their skin’s sensitivity to UV light. Then, in a series of treatments, a qualified healthcare professional exposes the affected skin to prescribed doses of UVA light.

According to a 2017 meta-analysis, progress is typically evident after 6–12 months of therapy.

Skin camouflage

While many people feel comfortable or enjoy how vitiligo looks, it may not be comfortable for everyone with the condition.

In cases of mild vitiligo, a person can camouflage the white patches with colored cosmetic creams and makeup. They can select tones that best match their skin tone.

Topical corticosteroids

Corticosteroid ointments are creams containing steroids. A 2017 review of studies concludes that applying topical corticosteroids to the white patches is an effective treatment.

Corticosteroids should be used with caution on the face and only under the guidance of a physician because of potential side effects, such as:

  • First, acne lesions
  • Second, spider veins
  • Lastly, thinning of the skin

Calcipotriene (Dovonex)

In fact, calcipotriene is a form of vitamin D used in topical therapy, often in combination with corticosteroids or phototherapy. Side effects may include:

  • itching
  • redness
  • burning

Drugs affecting the immune system

The topical medications tacrolimus and primecrolimus are drugs known as calcineurin inhibitors. They may help with smaller patches of depigmentation.

However, pimecrolimus contains a boxed warning from the Food and Drug Administration (FDA) about rare cases of malignancy, such as skin cancer and lymphoma, reported in people treated with calcineurin inhibitors.

Skin grafts

In a skin graft, a surgeon carefully removes healthy patches of pigmented skin and uses them to cover affected areas.

This procedure is not very common because it takes time and can result in scarring in the area.

Blister grafting involves producing a blister on more typical skin using suction. The top of the blister is then removed and placed on an area where the pigment was lost.

Tattooing

Micropigmentation, or medical tattooing, includes implanting pigment into the skin. It may work in people with light to medium skin tones.

Drawbacks can include difficulty matching the color of skin and the fact that tattoos fade but do not tan. Sometimes, skin damage caused by tattooing can trigger another patch of vitiligo.

Depigmentation

Depigmentation can be an option when the affected area is widespread, covering half of the body or more. It works by reducing the skin color in unaffected parts to match the whiter areas better.

Depigmentation involves applying strong topical lotions or ointments, such as monobenzyl ether of hydroquinone (MBEH), 4-methoxyphenol, and phenol.

The treatment is permanent, but it can make the skin more fragile. In addition, people must avoid extended exposure to the sun. Depigmentation can take 1–4 years depending on the depth of the original skin tone.

Ruxolitinib (Opzelura)

Opzelura is a topical Janus kinase (JAK) inhibitor. It’s the only medication approved by the FDA to restore lost pigment in people with vitiligo. It can treat a small area of the body in people 12 years and older with nonsegmental vitiligo.

Prognosis

Vitiligo is not fatal. People with this condition can lead happy and healthy lives.

However, the diagnosis can be emotionally challenging for some people. Some develop a concern about their appearance, especially as it grows to larger areas of the skin, which can affect one’s quality of life.

People can also develop secondary conditions, such as inflammation in the ear or eyes.
