Skin needling, also called micro needling therapy or collagen induction therapy (CIT) is a minimally invasive skin-rejuvenation procedure that involves the use of a device that contains several fine needles. The needles are used to puncture the skin to create a controlled skin injury. Each puncture creates a channel and triggers the body to heal these microscopic wounds by producing new collagen and elastin. Through the process of neovascularization and neocollagenesis, there is improvement in skin texture and firmness, as well as reduction in scars, pore size, and stretch marks. When utilized for generalized skin resurfacing, products such as topical growth factors, platelet rich plasma, and anti aging serums are better absorbed in the skin as an adjunct to treatment.
What to expect
Topical anesthetic cream is used to keep the patient comfortable during the procedure. Multiple treatments will be necessary as the number of needling sessions depends on the individual skin condition. Four to six treatments may be recommended for mild to moderate acne scarring, whereas deeper scars, stretch marks, and wrinkles may require more then five treatments. An interval of 4 to 6 weeks between treatments is typically recommended. Some redness may occur immediately after treatment, but it usually subsides by the next day so there is little to no downtime.
