Using Microneedling in the Treatment of Vitiligo

The document discusses the use of microneedling as a treatment for vitiligo, a pigmentary skin disorder characterized by white patches on the body due to the absence of pigment-producing cells in the epidermis. Microneedling, which can be performed using various tools such as manual rollers, derma rollers, automated needle pens, and microneedling fractional radiofrequency tools, is superior to traditional needle injections as it allows for better control over the injection's depth and reduces pain. The procedure involves minimal damage to the epidermis, creating micro-conduits in the stratum corneum that trigger a cascade of events in the dermal papillary layer, leading to the production of growth factors that stimulate collagen and elastin synthesis. The document concludes that microneedling is an effective and tolerable treatment for vitiligo, even in difficult-to-treat areas like the extremities or stubborn regions.
