Microneedling offers safe alternative to lasers

“Microneedling is a popular procedure that can be used as an alternative to laser treatments to provide low down time, and lower-cost treatments for similar indications in which lasers are used, such as rhytides and scars,” Catherine M. DiGiorgio, MD, a laser and cosmetic dermatologist at the Boston Center for Facial Rejuvenation, said in an interview.

“Many clinicians and/or providers utilize microneedling in their practice also because they may not have the ability to perform laser and energy-based device treatments,” noted Dr. DiGiorgio, who was asked to comment on the study findings. “Microneedling is safer than energy-based devices in darker skin types due to the lack of energy or heat being delivered to the epidermis. However, as shown in this study, darker skin types remain at risk for [postinflammatory hyperpigmentation], particularly in the hands of an unskilled, inexperienced operator.”

Dr. DiGiorgio said she was not surprised by the study findings. “Microneedling creates microwounds in the skin, which contributes to the risk of all of the side effects listed in the study. Further, the proper use of microneedling devices by the providers performing the procedure is variable and depths of penetration can vary based on which device or roller pen is used and the experience of the person performing the procedures. Depth, after a certain point, can be inaccurate and can superficially abrade the epidermis rather than the intended individual microneedle punctures.”

Laser and energy-based device treatments can be performed safely in patients with darker skin types in the hands of skilled and experienced laser surgeons, said Dr. DiGiorgio. However, “more studies are needed to determine the effectiveness of microneedling alone compared to other treatment modalities. Patients tend to select microneedling due to affordability and less down time; however, sometimes it may not be the best treatment option for their skin condition.

“Patient education is an important factor because one treatment that worked for one of their friends, for example, may not be the best treatment option for their skin complaints.”

Dr. DiGiorgio added that there are few randomized, controlled trials comparing microneedling to laser treatment. “More studies of this nature would benefit the scientific literature and the addition of histological analysis would help us better understand how these treatments compare on a microscopic level.”

The study received no outside funding and the author has no disclosures. Dr. DiGiorgio has served as a consultant for Allergan Aesthetics.
