308 nm Excimer Treatment for Vitiligo in Amman
Targeted UVB Phototherapy for Localized Vitiligo, Selected Psoriasis Plaques and Selected Alopecia Areata
EXCIMER IS A TREATMENT TOOL - NOT A SUBSTITUTE FOR DIAGNOSIS.
The 308 nm excimer delivers targeted UVB phototherapy directly to selected affected patches while limiting unnecessary exposure of surrounding uninvolved skin.
At Nova Derma, we use the Kernel 308 nm Excimer as part of a dermatologist-led treatment plan. The diagnosis, location, extent and activity of the condition determine whether targeted treatment is appropriate.
How Targeted 308 nm Treatment Works
The Kernel 308 nm Excimer directs UVB light at selected affected patches. Unlike whole-body phototherapy, it treats limited areas rather than exposing large areas of uninvolved skin. This makes targeted treatment particularly useful when the condition is localized enough for individual patches to be treated directly.
## Conditions we may treat with 308 nm excimer
- Localized vitiligo. Vitiligo is the main focus of this page. In appropriately selected localized patches, 308 nm excimer may be used to encourage repigmentation as part of an individualized vitiligo plan. Response varies by body site and disease characteristics: facial areas may respond better than fingers, hands and feet, and no individual result can be guaranteed.
- Selected localized or persistent psoriasis plaques. For a limited number of persistent plaques, targeted 308 nm UVB can be directed to affected skin while minimizing exposure of surrounding normal skin. Excimer is not intended to replace systemic or broader treatment when psoriasis is widespread, severe or significantly affecting quality of life.
- Selected localized alopecia areata, as an adjunct to medical treatment. Response in alopecia areata is less predictable than in vitiligo or localized psoriasis, so patient selection and follow-up are particularly important.
Depending on the diagnosis, targeted phototherapy may be used alongside topical or other medical treatment rather than as the only therapy.
There is no fixed number of sessions. The course depends on the diagnosis, location, size of the treated areas, disease activity and individual response, and progress is judged over time rather than after a single visit.
Who Is a Good Candidate?
308 nm excimer is most useful when the condition is localized and suitable for targeted phototherapy. Assessment by the dermatologist comes before any treatment decision.
Most Useful When
- The condition is localized, so individual patches can be treated directly.
- Vitiligo is confined to selected patches and the dermatologist considers targeted treatment appropriate.
- There is a limited number of persistent psoriasis plaques that can be directed to selectively.
- Alopecia areata is localized, and excimer is being used as an adjunct to condition-specific medical treatment.
Treatment May Need to Be Modified or Postponed If There Is
- Significant irritation or blistering in the treatment area.
- Sunburn.
- Active skin infection.
- A photosensitivity disorder.
- Medication that significantly increases photosensitivity.
- A previous excessive reaction to phototherapy.
Treatment is generally well tolerated. Some patients feel mild warmth, and temporary redness or itching can occur afterward.
During and After a Treatment Session
The handpiece is directed to the selected treatment areas, and the treatment dose is adjusted according to the diagnosis, body area, skin response and any previous-session reaction.
- Sessions can be relatively brief when only small or limited patches are involved.
- Temporary redness.
- Mild warmth or itching.
- Temporary darkening or increased pigmentation of treated skin.
- Occasionally a stronger reaction such as blistering, if the skin response is excessive.
The skin response is reviewed and used to guide subsequent treatment. Targeted phototherapy usually involves a course of repeated treatments, and progress is judged over time.
Is Excimer the Same as Whole-Body Phototherapy?
No. Excimer is targeted to selected patches. Whole-body or cabinet phototherapy treats a much larger skin surface and may be more appropriate when disease is widespread. The 308 nm excimer at Nova Derma is therefore a localized treatment option, not whole-body phototherapy.
Is 308 nm Excimer Appropriate for Your Condition?
If you have localized vitiligo, limited psoriasis or selected localized alopecia areata, dermatologist assessment can determine whether targeted 308 nm phototherapy fits the diagnosis and treatment goal.
