Laser-Assisted Drug Delivery on the Face: A Systematic Review of Indications and Outcomes

Abstract

Laser-assisted drug delivery (LADD) has gained prominence as a promising technique with the potential to enhance topical drug skin penetration and absorption. However, the effectiveness of various laser-assisted facial procedures remains unclear. This systematic review aimed to explore and summarize the evidence regarding the indications, clinical outcomes, and adverse effects of LADD performed on the face. Based on a predetermined protocol, an electronic search in MEDLINE, Scopus, the Cochrane Library, and CENTRAL electronic databases was conducted. Eligible studies comprised prospective controlled trials that explored the utility of laser-assisted techniques for topical medication facial application and reported on efficacy and/or safety. Secondary outcomes encompassed patient satisfaction. This review included 12 prospective controlled studies involving a total of 271 participants. LADD, through various laser types, topical medications, clinical protocols, and follow-up assessments, showed enhanced melasma, facial rejuvenation, scar, and periprocedural laser outcomes without increased risk of adverse effects. This review provides evidence that LADD is an effective and safe adjunct for various facial procedures. It also highlights the necessity for further high-quality studies with larger sample sizes, standardized treatment protocols, and evaluation of long-term outcomes and adverse effects in order to elucidate the potential of laser-assisted drug delivery.
