Abstract
Since it has been developed and improved over the last two decades, microneedling is one of the few examples that combine technology and simplicity. It is an effective, safe, and minimally invasive technique involving puncturing of the skin by rolling a handheld device with fine needles. The success of the technique is precisely to provide regeneration rather than cicatrization. As opposed to ablative procedures, microneedling preserves the epidermis and promotes normal collagen formation in place of scar collagen [1]. In addition to acne scars, it is also used for skin rejuvenation, other etiologies scars, stretch marks, alopecia, acne, hyperhidrosis and as a transdermal delivery system for therapeutic drugs and vaccines (drug delivery) [2].
