Microneedling, also referred to as collagen induction therapy (CIT), is performed for a variety of concerns with the ultimate goal of stimulating collagen with new skin growth. There are many microneedling devices on the market, all of which perform the same function. It is the depth of penetration of the needles, which is determined by the practitioner, that vary and affect the treatment outcome. More than one treatment is required, with the number of treatments contingent upon the skin concern and depth of the needles. Superficial treatments usually have little to no downtime, while aggressive treatments may result in several days of redness and crusting.
