D Printing of Topical Patches with Salicylic Acid: A New Frontier in Cosmetics and Pharmaceuticals

Abstract

3D printing is heavily researched in the pharmaceutical field over the last two decades and, more recently, in cosmetics research. Fused deposition modelling (FDM) is one of many methods of printing. The FDM process allows printing structures in various sizes and shapes by using read-ymade filaments and/or filaments loaded with active ingredients produced by various methods. However, using FDM for producing topical applications for the skin is limited. Therefore, in this work, FDM is used to print topical patches containing salicylic acid for acne treatment. By utilizing Eudragit EPO as the polymer, the patch can be printed at a lower temperature, safeguarding the integrity of salicylic acid. The patch shows good mechanical strength, and successful in vitro release of salicylic acid is achieved. This research signifies the potential of 3D printing for efficient and customizable skincare applications.
