The number of patients developing sterile abscesses because of hyaluronic acid (HA) filler procedures has increased for unknown reasons. We described this adverse reaction after filling with Juvederm Volux ® , the latest innovative product in the Vycross range of technology. We presented five patients with recalcitrant sterile abscesses after filling with Juvederm Volux ® who did not respond to the traditional therapy but whose lesions were resolved with the "Munhoz-Cavallieri lavage protocol" developed and recently published by the present authors. ( SKINmed . 2023;21:27-33).

Background: In recent years, fillers procedures with hyaluronic acid (HA) have grown significantly. Despite HA relative safety, the number of cases of complications after injections has grown, and in many of which, we are not aware of or have little control over., Aims: In this article, the authors describe a new adverse reaction after filling with HA injection, the sterile abscess., Patients/methods: We present eight patients with similar clinical, laboratory, and ultrasound characteristics for sterile abscess and report a new therapeutic modality for it., Results: All cases were treated with "Munhoz-Cavallieri Lavage Protocol" procedure with complete resolution., Conclusions: "Munhoz-Cavallieri Lavage Protocol" serves as a guideline in diagnosis and management of sterile abscess., (© 2022 Wiley Periodicals LLC.)

Introduction: The use of hyaluronic acid (HA) as a dermal filler is considered safe. However, as new brands come to the market, reports of adverse events are becoming more and more common., Objective: To describe a particular type of adverse effect that, unlike the erythematous, indurated, and painful nodules described in the literature as "angry red bumps," is characterized by noninflammatory, stony-like nodules that appear in sites previously treated with HA., Methods: The report of four patients who presented this complication, and the occurrence of two HA syringes from the same batch that had hardened the product inside at the time of filling., Conclusion: The authors propose the nomenclature "happy bump" to group adverse reactions to HA that translate into noninflammatory nodules, with a stony consistency, appearing up to 4 weeks (recent) or after one month (late) in sites previously treated with AH., (© 2022 Wiley Periodicals LLC.)

Background: Facial filling based on hyaluronic acid (HA) is an esthetic procedure that is widely performed worldwide., Methodology: Fifty patients underwent facial filling based on HA, and 10 board-certified dermatologists evaluated clinical photographs before and after the procedure and completed a questionnaire to provide information about the procedure., Results: All doctors and 96% of patients were agreed about the pre- and postprocedural photographs. Physicians were more aware of the possibility of frequent pain and erythema. Both groups showed agreement in their responses on the following topics: the possibility of hematoma and edema, a lack of secretion, improvement in patients' self-confidence, recognition of the procedure by third parties, and knowledge of the procedure by the dermatologists themselves. However, physicians tend to overestimate the possibility of erythema, pain, and edema; they also tend to minimize the duration and discomfort of postprocedural edema and the risk of third parties noticing patients' HA filling and how much it bothers patients when third parties do notice., Conclusion: Doctors and patients disagree on some questions about what actually happens and what is supposed to happen in facial filling procedures based on HA., (© 2021 Wiley Periodicals LLC.)

In the last few decades, there has been a substantial increase in the population of people over 60 years of age. Most of them maintain a good general health and physical activity and fitness. For these individuals there is a good number of dermatologic procedures, medications, and cosmetics that can be prescribed to improve the aspect of skin aging, providing an improvement in their self-esteem and quality of life as a result of their better look. We will discuss the mechanisms of skin aging, and the procedures and substances used to minimize its deleterious effects, such as sunscreens, estrogens, chemical peels, toxin botulinum, fillers and surgical procedures, among others. The use of makeup and the adverse reactions to cosmetics will also be mentioned.
