Microneedling involves puncturing the skin with small needles. The skin will likely be numbed before treatment to eliminate or at least decrease pain and discomfort. A penlike tool named a dermaroller is utilized in order to insert tiny stainless-steel needles into the skin to cause microinjuries or punctures.
As a result of these tiny abrasions, the skin amps up collagen production in order to heal, according to a study published in March 2017 in Dermatologic Surgery. The goal is for the damage caused by the needles to stimulate your body to send healing agents in the form of elastin and collagen to the area of treatment to repair the skin.
The treatment will take between 10 and 20 minutes, though you’ll need to buffer in more time if you’re receiving topical anesthesia. There are usually multiple sessions required, spaced one month apart. The needles will be inserted deeper into the skin at each following session, since the skin will become thicker and more able to withstand a deeper penetration over time.
