Navigating Laser Treatments for Scars: The Physical and Emotional Journey.

INTRODUCTION: The physical and emotional burden that scars impose on people's lives has been the concern of dermatological research for quite some time. Usually, the available literature on the topic draws a grim image containing solely dry medical facts. The present study deviates from this approach by reflecting a solution-centered study which has also touched on the quotidian life of an average person. The overall intention of the present experiment was to inspect how a holistic approach to scars in dermatology can be crucial for the patient's quality of life. METHODS: This pilot study compiles data collected through the Patient and Observer Scar Assessment Scale (POSAS) and the Dermatology Life Quality Index (DLQI) from the same set of patients within the span of a year. Sixty patients with diverse scar profiles were asked to rate POSAS and DLQI in every session. A combination of EBDs was used based on the scar examination. Student's t-test was run to validate the data. RESULTS: The evaluations by POSAS and DLQI indicate significant improvement in the physical aspect of the scar as well as the patient quality of life a year after the first treatment. According to mean values collected from POSAS, there is a direct correlation between average patient evaluations and physician assessments. Thus, EBDs prove to be efficient in improving the QoL of scar patient. The 20 patients who had reported mild side effects after treatments recovered fully within a few days after the sessions. No patient reported severe side effects. DISCUSSION: Apart from the physical indications that scars bring about into patients' lives, the psychological repercussions caused by scars have a major effect on the QoL of the patients. These repercussions can be divided into individual and social. At the individual level, scars have a profoundly negative effect on the image of the self which leads to several different psychological complications by time. At the social level, scars affect the radius of physical movement besides the quality of the patient's activities. Therefore, EBDs as effective treatment methods can improve itchiness, pain, and so forth, of the patient, and can also improve the psychological aspect. CONCLUSION: All in all, the present study aims to produce a more panoramic perspective on the concern of scars in the field of dermatology, centering around EBDs as a solution for improving scar patient QoL. With a focus on the efficacy of EBDs in the scar treatment, and with reference to studies on the topic, it is safe to assume that the earlier the scar treatment initiates, the better the outcomes. Departing from this point, in the future of cosmetic dermatology, prepping the skin by EBD treatments before surgery is imaginable.

Hyaluronan Hybrid Cooperative Complexes Injection as a Biostimulation for Postobese Skin Laxity in the Arm: A Histopathologic Study.

Background: The Hybrid Cooperative Complexes of high and low molecular weight hyaluronic acids (HHCC) improve skin structure and bioactivity. Massive weight loss damages cellular composition and morphological structure of skin. An injective treatment of postobese skin consisting of HHCC may have a role in counteracting these histopathological alterations. Objectives: To analyze the histological effects of HHCC injection in the cutaneous tissues of massive weight loss patients suffering from arm laxity. Methods: Nine ex-obese patients with postweight-loss-related arm laxity and ptosis requiring brachioplasty were prospectively recruited at the first author's department. HHCC injection was performed on only 1 arm, which included 2 injective sessions separated by 30 days. One month posttreatment, patients underwent a bilateral brachioplasty, and the surgical specimens were histologically examined, searching for any variation in the cutaneous connective tissue following injections. Histology on treated specimens showed a statistically significant increased density of elastic fibers along with a lower fragmentation of the same fibers compared to the untreated tissue. Fibroblasts demonstrated a swollen appearance as if involved in a bioactivation process. Results: Treatment with HHCC increases the number of elastin fibers and determines a more regular elastin deposition and architecture, as well as the bioactivation of fibroblasts. The contralateral untreated area showed an irregular structure with elastosis and elastolysis. Conclusions: More studies are necessary, but histologically proven benefits are demonstrated in the HHCC-treated skins when compared with basal controlateral skin. These data support the use of HHCC formulations for the treatment of postobese skin laxity.

Educational strategies to combat harmful cosmetic dermatology trends in Generations Alpha and Z.

This contribution argues in favor of implementing comprehensive educational strategies to combat the harmful effects of social media (SM) on body image and self-perception among Generations Alpha and Z. These generations are often exposed to unattainable beauty standards that can lead to distorted self-perceptions and body image disorders such as Zoom dysmorphia. To address this issue, we propose embedding health education, critical media literacy, and active parental involvement in educational curricula. The goal is to help young individuals develop the skills necessary to critically evaluate and navigate the pressures of SM. We believe that incorporating health education, critical media literacy, and active parental engagement into school programs is urgently needed to counteract the adverse effects of SM on body image and self-perception. These initiatives will equip young people with the necessary tools to evaluate SM content critically, navigate SM influences more safely and effectively, and develop a more resilient and informed perspective. This proactive educational approach is vital for improving mental health outcomes and mitigating the psychologic impacts of digital media. We hope that this comprehensive strategy will ultimately help future generations face SM pressures with confidence and critical awareness.

The growing importance of ultrasonography in cosmetic dermatology: An update after the 23rd IMCAS Annual World Congress (2022).

BACKGROUND: Ultrasound (US) has been used for many years in the field of medicine. Many specialties have embraced US as a quick, painless, and relatively inexpensive tool to assist the clinician in determining anatomy, pathology, and aid in diagnostic or therapeutic procedures. US allows for precise mapping of cutaneous and subcutaneous structures in the face, in particular vascular structures. The use of US leads to reduced chances of complications and clinical failures, rendering more safety and high quality. METHODS: US is considered the first-imaging technique for dealing with fillers and managing their potential complications. US can be deployed for vascular mapping, safe placement of fillers, and directed low-dose hyaluronidase reversal of vascular adverse events. It is a noninvasive imaging modality that provides a good definition for studying the skin, deeper layers, and blood flow in real time. In other words, we go from static to dynamic anatomy. In addition, US can guide with the application of botulinum toxin, in order to define the muscular planes. US may contribute to a more personalized procedure, better cosmetic results, and help to avoid complications. In general, physicians tend to use it for prevention. Last, for research purposes, US examination provides valuable information on the behavior, longevity, and interaction of the filler within the tissues. CONCLUSION: This new approach for US-guided treatments is a very practical and an effective method in cosmetic dermatology. As doctors, we owe it to our patients to do our best to prevent any harm. We feel that in near future, US will be an essential diagnostic tool in any dermatology or cosmetic doctor's office to both ensure safety and provide legal protection for the professional.
