Microneedling has been shown to be an effective treatment for both acne scars and the associated hyperpigmentation observed in patients with dark skin color, according to the results of a study conducted in the Department of Dermatology at the Jordan University of Science and Technology in Irbid, Jordan, and published in the Journal of Cosmetic Dermatology.

The primary objective of the study was to evaluate the improvement in pigmentation linked to acne scarring in patients with dark skin achieved by the use of microneedling. Secondary objectives included assessment of postacne scarring improvement and the safety of microneedling in pigmented skin.
