Role of microneedling in vitiligo

Abstract

Vitiligo isn’t only a cosmetic illness; it is accompanied by social ostracism and stigmatisation, resulting in a significant psychological burden for those afflicted. A range of therapeutic modalities has been employed, exhibiting varying re-pigmentation rates, such as: intralesional, systemic and topical corticosteroids; psoralen ultraviolet A photochemotherapy and narrow-band ultraviolet B phototherapy; monochromatic excimer light laser; calcineurin inhibitors; afamelanotide; prostaglandin F2 alpha analogue (Latanoprost); erbium laser-assisted dermabrasion; CO2 fractional laser; and surgical procedures. However, an adequate therapy for vitiligo remains elusive. A method utilising needling in vitiligo demonstrated positive levels of re-pigmentation. It may be accomplished with basic injection needles or microneedling (MN) apparatuses, including manual rollers, automated needle pen devices, dermarollers, and MN fractional radiofrequency devices. The recovery rates after treatment with MN have enhanced patient satisfaction and professional knowledge of this prevalent therapy for vitiligo.
