AbstractThe acquired pigmentary skin disorder known as vitiligo, which appears as white macules and patches all over the body, is brought on by the lack of pigment-producing cells from the epidermis. Micro needling has been utilized in Vitiligo treatment. Simple injection needles or microneedling tools like manual rollers, derma rollers, automated needle pens, and micro needling fractional radiofrequency tools can be used to perform the procedure. Microneedling is superior to traditional needle injections because it allows greater control over the injection's depth and reduces pain. Transdermal medicine delivery with micro needle delivery systems is non-painful and requires no cutting or stitching. Minimal harm to the epidermis is caused by the needles as they puncture the stratum corneum and form micro-conduits. In the dermal papillary layer, this causes a cascade of events that culminates in the creation of growth factors that drive collagen and elastin synthesis. Solid, coated, dissolving, hollow, and swell able polymer micro needles manufactured using micro fabrication process are all viable options for this application. According to the information that is currently available, micro needling is an effective and enjoyable treatment for vitiligo. It can also be useful for treating difficult-to-treat areas like the extremities or stubborn regions.
