Microneedling is a technique in which micro-channels are created in the skin by means of very small microneedles, which ensure that natural wound healing is stimulated. This procedure triggers growth factors that regenerate the skin without creating scar tissue. The non-inflammatory growth factors or keratinocytes are mainly located in the top layer of the skin. The better these work, the better the fibroblasts and the melanycotes will work and these in turn will produce more collagen.
