Targeted Light / Excimer (308 nm)
What is Targeted Light / Excimer Laser (308 nm)?
308 nm Excimer Laser for Vitiligo is particularly beneficial for individuals with localized vitiligo and areas that require precise, targeted treatment.
Ideal Candidates for Excimer Laser Therapy
- Patients with limited or localized vitiligo patches
- Individuals with stable or slowly progressing vitiligo
- Patients who have not achieved desired results with topical medications alone
- Children requiring focused treatment with minimal exposure to unaffected skin
- Individuals with facial, neck, or cosmetically sensitive lesions
- Patients looking for a non-invasive treatment option
When Excimer Laser May Not Be Recommended

How 308 nm Excimer Laser for Vitiligo Helps Restore Skin Pigmentation
Vitiligo occurs when melanocytes, the pigment-producing cells in the skin, are damaged or destroyed by an autoimmune response. 308 nm Excimer Laser for Vitiligo can target affected areas to help stimulate repigmentation.
Mechanism of Action
The 308 nm Excimer Laser works by:
- Delivering targeted UVB light to depigmented patches
- Suppressing abnormal immune activity affecting melanocytes
- Stimulating dormant melanocytes within hair follicles
- Encouraging migration of pigment cells into affected areas
- Promoting melanin production and gradual repigmentation
Because treatment is focused only on vitiligo patches, higher therapeutic doses can often be delivered safely and effectively.
