Microneedling is a cosmetic procedure. It involves pricking the skin with tiny sterilized needles. The small wounds cause your body to make more collagen and elastin, which heal your skin and help you look younger. You might also hear it called collagen induction therapy.
As soon as the deepest layers of your skin are penetrated by the needles, “micro-wounds” are created. This triggers your body's wound healing processes to heal your micro wounds immediately. However, the most dramatic results will not be visible until four to six weeks after treatment.
As a general rule of thumb, microneedling treatment can be safely done about once a month or every 4 to 6 weeks.
