Skin needling is also called micro-needling 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 a controlled skin injury.
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 but typically 0.5 mm length is used to minimise bleeding and enable rapid recovery.
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.
