What is Microneedling?

Microneedling therapy or collagen induction therapy (CIT) is a minimally invasive skin-rejuvenation procedure that involves the use of a device that contains fine needles used to puncture the skin to create a controlled skin injury. Each puncture creates a channel that triggers the body to fill these microscopic wounds by producing new collagen and elastin. Through the process called neovascularization and neocollagenesis, there is improvement in skin texture and firmness, as well as reduction in scars, pore size, and stretch marks.

Microneedling has had superior results and is a simple and fast method for safely treating wrinkles and scars. Because the epidermis is not compromised, the procedure can be repeated safely and is also suited to regions where laser treatments and deep peels are not typically performed. Microneedling therapy is now becoming widely used as a treatment for photoaged skin to improve the skin’s appearance and quality, and to improve or even prevent scarring.

It can be performed in an office setting and does not require extensive training or costly equipment. It is cost-effective, and can be done on areas of skin that may not be suitable for peeling or laser resurfacing, such as around the eyes and mouth, hands, and chest. The procedure is well tolerated with minimal downtime, and can be easily personalized by going deeper on some areas where skin damage requires a more aggressive approach.

A Topical anesthetic cream is used to keep the patient comfortable during the procedure. The number of needling sessions depends on the individual skin condition. Three or four treatments may be recommended for mild to moderate acne scarring, whereas deeper scars and stretch marks may require upward of five treatments. An interval of 4 to 6 weeks between treatments is typically recommended. Many practitioners are also doing maintenance treatments at intervals of 6 to 12 months. When utilized for generalized skin resurfacing, products such as topical growth factors and antiaging serums are combined with treatment.
