Vitiligo

• Vitiligo is a long-term skin condition where the skin loses its natural color (pigment), resulting in white patches that can appear anywhere on the body. It happens when melanocytes—the skin cells that produce melanin—are destroyed or stop functioning. Vitiligo is not contagious, but it can affect a person’s confidence and emotional well-being.

• The exact cause of vitiligo is still unknown, but experts believe it is linked to a combination of autoimmune, genetic, and environmental factors.

​

• Autoimmune response:

  • The body mistakenly attacks its own pigment-producing cells

​

• Genetics:

  • Runs in families in about 30% of cases

​

• Other triggers may include:

  • Stress

  • Skin injury (cut, sunburn)

  • Exposure to certain chemicals

  • Thyroid disease or other autoimmune conditions

• Vitiligo can affect people of any age, gender, or skin tone, but is often more noticeable in people with darker skin.

​

• Types of Vitiligo:

  • Non-segmental (Generalized):

    • Most common, affects both sides of the body (e.g., both hands, knees)

  • Segmental:

    • Appears on one side or part of the body

  • Localized or focal:

    • Affects only a few small areas

• White or pale patches on skin

• Common on hands, face, arms, feet, and around body openings (mouth, eyes)

• Graying of hair, eyelashes, or beard early in life

• Loss of pigment inside the mouth or nose

• Usually not itchy or painful, but may feel dry

• Vitiligo treatments aim to restore skin color, stop the spread, and improve appearance and confidence. There is no cure, but several options can help manage the condition.

1. Topical Corticosteroids

​

• These reduce inflammation and may help restore pigment.

  • Best for localized or early-stage vitiligo

  • Common examples: Clobetasol, Betamethasone

  • Most effective on face or trunk, less so on hands and feet

​

• Long-term use can thin the skin—use under medical guidance.

​

2. Topical Calcineurin Inhibitors

​

• Non-steroidal creams that suppress the immune system locally.

  • Examples: Tacrolimus (Protopic), Pimecrolimus (Elidel)

  • Safe for delicate areas like the face, eyelids, and genitals

  • Fewer side effects than steroids, safe for children and long-term use

​

3. Phototherapy (Light Therapy)

​

• Narrowband UVB (NB-UVB) is commonly used.

  • Helps stimulate melanocytes to produce pigment

  • Can be done at home (with a device) or in clinics

  • Requires multiple sessions per week for several months

​

• Works well for widespread vitiligo or resistant patches

​

4. Oral Medications

​

• Used in more aggressive or widespread cases.

  • Corticosteroids (short-term) to control spreading

  • Immunosuppressants like Methotrexate or Azathioprine (in some cases)

​

• These come with more side effects and are usually a last resort.

​

5. Skin Camouflage and Cosmetic Products

​

• Used to temporarily blend white patches with the surrounding skin.

  • Tinted creams, self-tanners, or camouflage makeup

  • Dermablend and Microskin are popular brands

  • Helps improve self-esteem and confidence in social settings

​

6. Depigmentation Therapy

​

• For people with extensive vitiligo, this removes remaining pigment for a uniform skin tone.

  • Medication: Monobenzone cream

  • Permanent and requires commitment

• Mild Effects:

  • Skin dryness, redness, or irritation

  • Sensitivity to sunlight after light therapy

  • Temporary stinging (with tacrolimus or steroid creams)

​

• Serious (but rare):

  • Skin thinning (from steroid overuse)

  • Increased risk of skin infections

  • Long-term immunosuppressive drugs may weaken immune system

​

• 📝 Always follow medical guidance and use sunscreen during and after treatment.

• Doctors usually diagnose vitiligo by:

  • Physical exam of the skin

  • Wood’s lamp test (UV light to highlight depigmented patches)

  • Blood tests to check for autoimmune conditions (thyroid, diabetes, etc.)

  • Skin biopsy (rarely needed)

While you can’t prevent vitiligo, you can manage and slow its progression:

• Use Sunscreen Daily (SPF 30+):

  • Vitiligo patches are more prone to sunburn

​

• Moisturize daily:

  • Keeps skin healthy and prevents dryness or cracking

​

• Protect skin from injury:

  • Cuts or friction can sometimes trigger new patches

​

• Manage stress:

  • Emotional stress may worsen autoimmune responses

​

• Explore camouflage options:

  • Makeup or self-tanners can help improve appearance

1. Can vitiligo be cured?

• No. There’s no permanent cure, but treatments can help repigment the skin or control its spread.

​

2. How long do treatments take to work?

• Results can take several weeks to months. Phototherapy may require 6–12 months for visible improvement.

​

3. Is vitiligo dangerous?

• No, it’s not life-threatening or contagious. But it can have emotional or psychological impacts.

​

4. Can diet help vitiligo?

• No specific diet cures vitiligo, but a healthy, antioxidant-rich diet supports skin health.

​

5. Will vitiligo come back after treatment?

• Sometimes, especially under stress or sun exposure. Ongoing care helps reduce the risk.
