Excimer Laser for Vitiligo in Lucknow

How Excimer Laser Works

The excimer laser (or excimer lamp) delivers a focused beam of 308nm UVB light directly to the vitiligo patch. Unlike full-body phototherapy (narrowband UVB), the excimer targets only the affected area, allowing higher energy doses with faster results and less exposure to surrounding skin.

Excimer vs. Narrowband UVB

Best Candidates for Excimer

• Patients with limited vitiligo — fewer than 10 patches or covering less than 10% body surface
• Facial and neck patches — these areas respond particularly well
• Patients who cannot commit to full-body phototherapy sessions
• Children — targeted approach minimizes unnecessary UV exposure

Treatment Protocol

• Frequency: 2–3 sessions per week
• Session duration: 5–15 minutes (depends on number and size of patches)
• Initial response: Repigmentation dots may appear after 10–15 sessions
• Full course: 30–60 sessions typically
• Combination: Often used alongside topical tacrolimus for enhanced results

Realistic Outcomes

• Face and neck: 60–80% repigmentation achievable in many patients
• Trunk and limbs: 40–70% repigmentation
• Hands and feet: Most resistant — results are less predictable
• Some patches may not respond despite adequate treatment
