Microneedling (MN) is used for the treatment of scars, amongst other indications.

The aim of a new study published in Clinical, Cosmetic and Investigational Dermatology was toassess the use of MN for the treatment of scars.

This was a systematic review of the Medline database that included articles written in English and discussed the use of MN for the treatment of scars in human subjects.

Overall, 58 studies were selected for review, with a total of 1845 patients treated for acne scarring, hypertrophic or keloid scars, and those resulting from surgery, trauma, varicella or smallpox. MN and its counterpart fractional radiofrequency MN (FRF-MN) were used as monotherapy or in combination with topical, surgical or systemic modalities. MN and FRF-MN treatment resulted in clinical improvement of scar appearance from baseline. No serious adverse events occurred.

From the results, it was concluded that MN is a well-tolerated, minimally invasive procedure that can be used for the treatment of scars with a high level of patient satisfaction.
