Few studies look at microneedling for facial rejuvenation. For lines and wrinkles, one study showed that six dermaroller sessions spaced two weeks apart led to increases in collagen (particularly types I, III and VII), total elastin and tropoelastin. Study patients had Fitzpatrick skin types III and IV, and Glogau class II to III wrinkles. Average investigator-assessed improvement in wrinkle appearance and skin texture based on photographs increased from a range of 20 to 25% one month posttreatment to 55 to 65% at three months.9 “This is one of the only studies I found using microneedling for facial rejuvenation in terms of treating fine lines and wrinkles, however; I know controlled trials are currently being conducted and should be published very soon,” she says.
Many devices now provide fractional radiofrequency microneedling (RFMN). With this technology, insulated needles penetrate the skin to deliver RF energy (and controlled heat) to the deep dermis to stimulate collagen production, Dr. Weinstein Velez says. Fractional RFMN has been shown to be useful for the same indications as microneedling and for additional indications including treatment of excessive sebum secretion, active inflammatory acne and hyperhidrosis.
