Vitiligo (white spot disease)

Overview

In vitiligo (white spot disease), the skin loses its pigmentation in individual areas because the pigment-forming cells (melanocytes) are lost. Sharply demarcated white patches develop. The condition is frequently based on an autoimmune process.

The excimer laser can be used to treat circumscribed areas. It delivers monochromatic UV light at a wavelength of 308 nm in a targeted manner only onto the affected spots and spares the healthy skin. The aim is to stimulate repigmentation.

Areas of application

• Circumscribed vitiligo areas
• Vitiligo on the face and in other well-responding regions
• As a complement to further medically recommended measures

Procedure

1. Examination and consultation

   We assess the extent and location of the affected areas and discuss with you the treatment options and their limits.

2. Targeted excimer treatment (308 nm)

   The UV light is directed in a targeted manner only onto the depigmented spots. Through this pinpoint application, higher, effective doses can be reached without unnecessarily burdening the healthy skin.

3. Repeated sessions

   The treatment is carried out over several sessions. Repigmentation builds up slowly and varies from person to person; complementary topical therapies can be useful.

What to expect

• Vitiligo usually requires many sessions over an extended period.
• Repigmentation develops slowly and varies greatly from person to person; areas on the face usually respond better than, for example, the hands and feet.
• In the treated areas, a temporary, mild sunburn-like reaction can occur.
• Treatment success cannot be guaranteed.

Risks & notes

• Redness and a sunburn-like reaction in the treated area are temporarily possible.
• A temporary tanning of the surrounding skin can occur and usually recedes after the end of therapy.
• Because this is a UV treatment, blistering can occur if the dose is too high; with cumulatively high UV doses, a slightly increased long-term skin cancer risk cannot be entirely ruled out – as with any UV therapy. The dose is therefore medically controlled and limited; we discuss the individual risk with you.
• The treatment is usually a self-pay or IGeL service; private insurers often cover the costs.

Frequently asked questions

Is vitiligo curable?

Vitiligo cannot be cured in the strict sense. However, with treatments such as the excimer laser, repigmentation can be stimulated in suitable areas. Success varies from person to person.

How many sessions are needed?

As a rule, many sessions over an extended period are required. Repigmentation builds up slowly and varies from person to person.

Does the health insurance cover the costs?

The treatment is usually a self-pay or IGeL service. Private insurers often cover the costs. We clarify the framework with you in advance.
