What is micro needling and how does it work?
Micro needling is also called skin needling therapy,meso therapy or collagen induction therapy. It is a minimally-invasive non-surgical and nonablative procedure for facial rejuvenation that involves the use of a micro-needling device to create controlled skin injury.
As each fine needle punctures the skin, it creates a channel or micro-wound. The controlled injury triggers the body to fill these micro-wounds by producing new collagen and elastin in the papillary dermis. In addition, new capillaries are formed. This neovascularisation and neocollagenesis following treatment leads to reduction of scars and skin rejuvenation, i.e., improved skin texture, firmness and hydration.
There are various skin needling devices including Dermaroller? (Dermaroller GmbH); Dermapen? (Equipmed Pty Ltd; Australia) Derma-Stamps? (Dermaroller USA) and radial discs incorporating fine microneedles of various diameter and length, fabricated from a wide range of materials such as silicon, glass, metals, and polymers. The needles are up to 3 mm in length.
Professional skin needling is considered to be one of the safest skin treatment procedures. Unlike chemical peels, dermabrasion and laser treatments, skin needling causes minimal damage to the skin.
