Microneedling is a treatment that consists of causing microperforations in the skin with a handheld device. The injury causes a controlled inflammation capable of improving its appearance and paving the way for the penetration of substances placed after the procedure that are capable of brighting and rejuvenating the skin or even inducing hair growth. This technique associated with microneedling is called drug delivery. The procedure helps smooth lines and wrinkles, treat pores and acne scars. It is also indicated for the treatment of melasma, stretch marks and androgenetic alopecia.
