Phototherapy for Vitiligo: Causes, Treatment, and Symptoms

Vitiligo is a skin condition characterized by the loss of skin color in patches, caused by the destruction of melanocytes. Phototherapy is an effective treatment for this condition. Below is an overview of the causes, symptoms, and treatment options available for vitiligo.

Causes of Vitiligo

Several factors may contribute to the development of vitiligo:

  • Autoimmune Response:
    • The immune system may mistakenly attack melanocytes.
  • Genetic Factors:
    • Family history may increase the risk of developing vitiligo.
  • Environmental Triggers:
    • Sunburn, skin trauma, or exposure to certain chemicals can trigger vitiligo.
  • Hormonal Changes:
    • Hormonal fluctuations during pregnancy or puberty can contribute to the condition.
  • Stress:
    • Emotional stress may trigger or worsen vitiligo.

Symptoms of Vitiligo

The main symptom of vitiligo is the appearance of white patches on the skin:

  • Faded Skin Color:
    • Patches of skin that have lost their original pigmentation.
  • Varied Size:
    • Patches can vary in size and shape, and may appear anywhere on the body.

Phototherapy Treatment for Vitiligo

  • Types of Phototherapy:
    • UVB Therapy uses ultraviolet B light.
    • PUVA Therapy combines psoralen medication with UVA light.
  • How It Works:
    • Light stimulates melanin production in the skin.
    • Helps repigment the affected areas.
  • Treatment Sessions:
    • Sessions are typically scheduled two to three times a week.
    • Duration varies but usually lasts 15 to 30 minutes.
  • Aftercare:

    • Use sunscreen to protect treated areas from sun exposure.

What to Expect During Treatment

    • A dermatologist assesses your skin and treatment plan.
  • Procedure:
    • Protective eyewear is provided during the treatment.
    • Some may experience mild discomfort during the session.
