Vitiligo Treatment — Excimer Laser, DermaPen and PRP

Vitiligo is an autoimmune condition in which T-lymphocytes aberrantly target and destroy melanocytes — the pigment-producing cells of the epidermis — resulting in well-demarcated, depigmented patches. Repigmentation requires two simultaneous achievements: suppression of the autoimmune attack to prevent continued melanocyte destruction, and stimulation of surviving melanocyte progenitors in the hair follicle reservoir to migrate and repopulate the…

Derma Medical Clinic's combined vitiligo protocol addresses both requirements in sequence. The first stage is a DermaPen microneedling session over the depigmented patches: the micro-channels created by the needles extend through the epidermis into the dermis, transiently disrupting the barrier that ordinarily restricts the migration of hair follicle–resident melanocyte stem cells. Immediately after needling, activated PRP (platelet-rich plasma) is…

This completes one five-week cycle. The cycle is repeated; clinical data at Derma Medical Clinic and in the published literature suggest a minimum of five complete cycles for meaningful repigmentation, with response rates varying significantly by patch location — face, trunk and genitalia respond most readily, while hands and feet require more sessions. Session duration for each cycle stage ranges from the DermaPen and PRP session (approximately two hours…
