Permanent makeup (PMU) is a popular application for the correction of face and body imperfections. It can be applied over the facial area to correct the shape and color of eyebrows, to the eyelids to create permanent eyeliner shapes, and the lips to create permanent lipliner and lip shading features. Furthermore, its “medical” use on the scalp and men’s facial hair area to camouflage hair follicles and to cover hairless areas makes it popular for hair transplants. No matter how useful these procedures are, there are always mistakes and the factor of bad application which raises the number of patients who want to “remove” it or “correct” it on their face or body. In order to find a non-laser solution for PMU removal, we investigated the decolorization capacity of common plants and plant origin extracts on mouse models. Two methods were used for PMU decolorization. The first one included the use of traditional tattooing with needles combined with plant origin extracts applied over the tattooed area. The second one included the use of electroporation technology application with the combination of plant origin materials to remove the PMU colorants over the tattooed area. In both cases, the permanent makeup colorants for eyebrows, eyeliners, and lipliners were applied in vivo. Full article

Systems that analyse faces have seen significant improvements in recent years and are today used in numerous application scenarios. However, these systems have been found to be negatively affected by facial alterations such as tattoos. To better understand and mitigate the effect of facial tattoos in facial analysis systems, large datasets of images of individuals with and without tattoos are needed. To this end, we propose a generator for automatically adding realistic tattoos to facial images. Moreover, we demonstrate the feasibility of the generation by using a deep learning-based model for removing tattoos from face images. The experimental results show that it is possible to remove facial tattoos from real images without degrading the quality of the image. Additionally, we show that it is possible to improve face recognition accuracy by using the proposed deep learning-based tattoo removal before extracting and comparing facial features. Full article

Background and Overview: Gunpowder inclusion injuries are rare occurrences in the civilian sector but are more frequently encountered in the military setting. The authors report a case series of 3 active duty military service members treated by an Army hospital’s Oral & Maxillofacial Surgery service for the removal of embedded gunpowder particles so as to avoid traumatic tattooing. Case Description: Three otherwise healthy active duty military service members were treated for gunpowder inclusion injuries incurred while conducting live fire training exercises at a state-side military installation between 2018 and 2019. All 3 males presented with injuries of the same etiology: Their weapons malfunctioned, and while visually inspecting the action, a round exploded close to the face. This peppered the face with gunpowder particles that were both superficially and deeply embedded. Treatment focused on individual removal using fine forceps. The patients were followed up and healed quickly without any complications, specifically without traumatic tattooing from the gunpowder injuries. Conclusion and Practical Implications: Gunpowder inclusion injuries should be addressed quickly to remove the particles before epidermal healing occurs, thus avoiding the complication of traumatic tattooing. This surgical team recommends meticulous fine forceps removal as the treatment of choice for larger particles. Full article
