OBJECTIVES To review the history of nonablative technology and its applicability to darker skin types and to provide an objective look at the various published studies documenting the efficacy of nonablative technology. CONCLUSION Nonablative laser surgery can improve skin quality and acne scars in all skin types. Complications are rare but can occur. Future studies are required to compare the efficacy of the various nonablative technologies.
