Each pass makes thousands of tiny micro-injuries that switch on your skin's natural repair response. As it heals, skin rebuilds collagen and elastin, the proteins that keep it firm and smooth. Forehead lines, frown lines, crow's feet and upper-lip lines each improved by a full grade or more.
Biopsies of sun-damaged skin confirm the rebuild: more collagen (types I, III and VII) and more new elastin after microneedling. And in a trial with blinded raters, neck wrinkles improved 26% after 4 monthly sessions.
