Microneedling is a cosmetic procedure that stimulates collagen at deeper layers, without the use of wrinkle relaxers or dermal fillers. Only your natural blood products are being used to regenerate the skin and can either be an excellent treatment to combine with your injectables or stand-alone and produce incredible tightening and complexion results. 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.
