Skin Rejuvenation using Micro needling

Micro needling rejuvenates the skin by stimulating the production of collagen, hence the term collagen induction therapy. The procedure initiates the wound healing or inflammatory response, and with it the release of histamine and several growth factors in the dermal layer. Here, fibroblasts increase in number producing more collagen and elastin. New collagen can be developed up to a depth of 0.5mm using a 1.5mm needle. Micro needling also breaks down hardened scar strands and allows the dermal layer to revascularize. The new collagen produced by microneedling, is cross-linked in a natural basket-weave lattice, unlike the parallel arrangement of collagen fibres in scar tissue.

This unit includes the relationship between the inflammatory response and skin remodelling, skin ageing and disorders, topical anaethesia, and the principles of micro needling. It also covers vital information that clients must understand for them to make an informed consent for this procedure. Theory is assessed by short answer questions completed online, with oral questioning, observational checklists and case studies completed during practical training, which includes adaptation of procedures to meet the client’s needs using dermal rollers and automated devices.
