Excimer Laser (Vitiligo & Psoriasis)
Targeted 308nm ultraviolet laser therapy for vitiligo repigmentation, localised psoriasis, and other UV-responsive skin conditions.
At A Glance
Practical planning details to help you decide quickly.
- Sessions

- Session Duration
- 15–30 minutes
- Downtime
- None

- When Results Start
- Initial repigmentation signs in 6–10 sessions; meaningful response by 20–30 sessions
- Result Longevity
- Variable; maintenance sessions often needed to sustain repigmentation
What Is It?
The Excimer laser delivers a concentrated 308nm UVB wavelength — the therapeutic range for stimulating melanocyte activity and immune modulation — precisely to affected patches without exposing surrounding healthy skin.
In vitiligo, the 308nm beam triggers melanocyte proliferation and migration from follicular reservoirs at the patch margin, promoting repigmentation in areas where melanocytes remain viable.
Compared to conventional phototherapy (whole-body NB-UVB), Excimer laser is site-specific, allowing higher fluence delivery to active patches with a fraction of the total skin exposure — reducing side effects while improving localised response.
Benefits
- Targeted repigmentation in vitiligo patches
- Higher fluence than broad-panel phototherapy with less total UV exposure
- Effective for localised and stable patches
- No systemic medication required
- Can treat cosmetically sensitive areas (face, hands, neck)
The Process
A simple three-stage journey from consultation to recovery.
2
During
Calibrated 308nm beam delivery to each patch at prescribed fluence, building dose across sessions.
3
After
SPF guidance and session interval planning based on repigmentation response.
Who Is It For?
Suitable for stable vitiligo patches, localised psoriasis, and selected UV-responsive skin conditions assessed by dermatologist.
Ideal For
- Stable vitiligo with defined patches
- Vitiligo on face, neck, or hands
- Localised plaque psoriasis
- Patients who cannot tolerate systemic phototherapy
May Not Be Ideal If
- Rapidly spreading (active) vitiligo without stabilisation
- Photosensitive conditions or medications
- Universal vitiligo (>80% depigmentation) where repigmentation potential is limited
Pre-Care & Post-Care
Good preparation and aftercare are key to safe, consistent outcomes.
Before Treatment
- - Avoid self-tanning products or UV exposure before sessions
- - Inform doctor of all current medications (photosensitising drugs require review)
- - Keep treatment areas accessible and clean on session days
After Treatment
- - Apply broad-spectrum SPF to treated areas if exposed to sun
- - Do not use tanning beds or unprotected sun exposure between sessions
- - Attend sessions consistently for best cumulative response
Safety Notes
Every medical procedure has expected reactions and rare risks.
Combination Plans
Some concerns improve faster when treatments are sequenced intentionally.
