Vitiligo: Causes, Symptoms, Diagnosis, Treatment, and Prevention

The condition vitiligo is characterized by patches of color or pigment loss on the skin. It can affect the entire body, but it is more noticeable on areas exposed to the sun, such as the face, hands, and feet. While it is neither contagious nor harmful to the body, vitiligo can affect the quality of life and self-esteem of a person significantly.

What causes vitiligo?

It is believed that vitiligo is caused by an autoimmune disorder in which the immune system mistakenly attacks the cells that produce melanin, the pigment that gives skin its color. Some factors that may trigger or worsen vitiligo include:

  • Genetic predisposition: Vitiligo tends to run in families, and some genes have been linked to the condition.

  • Stress: Physical or emotional stress may trigger or aggravate vitiligo.

  • Sun exposure: Sunburn or excessive sun exposure may damage the skin and trigger vitiligo.

  • Chemical exposure: Some chemicals, such as phenols, catechols, and hydroquinones, may cause depigmentation of the skin.

  • Hormonal changes: Hormonal fluctuations, such as during pregnancy, puberty, or menopause, may affect the skin’s pigment production.

  • Skin injury: Cuts, burns, or infections may trigger vitiligo in some people.

What are the symptoms of vitiligo?

The main symptom of vitiligo is the appearance of white or light patches of skin that vary in size, shape, and location. It may be possible for the patches to spread or remain stable over time, and they may be symmetrical or asymmetrical. People with vitiligo may also experience hair loss, eye loss, mucous membranes in the mouth, nose, genitals, and anus.

  • Itching or burning sensation on the affected skin

  • Sensitivity to sunburn and skin cancer

  • Premature graying of the hair

  • Psychological distress and social stigma

How is vitiligo diagnosed?

Vitiligo is usually diagnosed by a dermatologist, a doctor who specializes in skin conditions. The diagnosis is based on:

  • Physical examination: The doctor will examine the skin and look for the characteristic patches of vitiligo. The doctor may also use a device called a Wood’s lamp, which emits ultraviolet light, to make the patches more visible.

  • Medical history: The doctor will ask about the onset, duration, and progression of the condition, as well as any family history or other medical conditions that may be related to vitiligo.

  • Skin biopsy: The doctor may take a small sample of the affected skin and examine it under a microscope to rule out other skin disorders, such as psoriasis, eczema, or fungal infection.

  • Blood test: The doctor may order a blood test to check for the presence of antibodies or other markers of autoimmune diseases, such as thyroid disease, diabetes, or anemia.

How is vitiligo treated?

There are no cures for vitiligo, but there are treatments that can help restore some color to the skin or even out the skin tone. Vitiligo treatment options depend on a variety of factors, including the extent, location, and type of the condition, the age, skin color, and preferences of the patient, as well as the availability and cost of the treatment. Some of the most common treatments include:

  • It may be possible to stimulate the growth of pigment cells or reduce inflammation with some topical creams, including corticosteroids, calcineurin inhibitors, and vitamin D analogs. It is possible for oral medications, such as psoralen, to enhance the effects of light therapy or to make the skin more sensitive to sunlight.

  • In light therapy, the affected skin is exposed to light sources, such as ultraviolet A (UVA), ultraviolet B (UVB), or narrowband UVB (NBUVB), to stimulate melanin production. In PUVA (psoralen plus UVA), light therapy is combined with psoralen, a drug that makes the skin more responsive to light.

  • An excimer laser can be used to target depigmented patches and stimulate pigment cell growth by focusing a beam of light.

  • Skin grafting, blister grafting, or tattooing are surgical procedures that involve transplanting healthy skin or pigment cells from one part of the body to another. Surgery is usually reserved for small and stable areas of vitiligo that do not respond to other treatments.

  • There are some people who choose to cover up the patches of vitiligo with makeup, self-tanners, and skin dyes. These products can help camouflage the skin and improve appearance, but they do not treat the underlying condition.

How can vitiligo be prevented?

There is no known way to prevent vitiligo, but some measures may help reduce the risk or severity of the condition, such as:

  • Avoiding or limiting exposure to the sun or other sources of ultraviolet light, and using sunscreen and protective clothing when outdoors.

  • Avoiding or minimizing contact with chemicals that may cause depigmentation, such as hair dyes, bleaches, or detergents.

  • Managing stress and practicing relaxation techniques, such as meditation, yoga, or breathing exercises.

  • Eating a balanced diet and taking supplements that may support the skin’s health, such as vitamin B12, folic acid, copper, zinc, or antioxidants.

  • Seeking professional help and joining support groups if vitiligo affects the mental or emotional well-being.
