Polynucleotides, complex molecules composed of nucleotides, have gained attention in aesthetic medicine for their potential to regulate gene expression and promote tissue regeneration. This review aims to provide an overview of the current practices and perceived effectiveness of polynucleotides in aesthetic medicine. A comprehensive search of the literature was conducted using keywords related to polynucleotides, cosmetic application, and aesthetic application. Studies were selected based on their relevance to aesthetic medicine and the inclusion of human subjects. The review found that polynucleotides have been used to improve skin texture, reduce wrinkle depth, and enhance facial appearance. The studies reported varying degrees of efficacy and safety, with some studies demonstrating significant improvements in skin elasticity and hydration. However, others reported limited or no benefits. The review also highlighted the need for further research to establish the optimal use and efficacy of polynucleotides in aesthetic medicine. While the existing literature suggests that polynucleotides may have potential benefits in aesthetic medicine, more research is needed to fully understand their mechanisms of action and optimal use. Clinicians should be aware of the current limitations and potential risks associated with the use of polynucleotides in aesthetic medicine.

Both the functions and equipment of dermatologists have increased over the past few years, some examples being cosmetic dermatology, artificial intelligence, tele-dermatology, and social media, which added to the pharmaceutical industry and cosmetic selling has become a source of bioethical conflicts. The objective of this narrative review is to identify the bioethical conflicts of everyday dermatology practice and highlight the proposed solutions. Therefore, we conducted searches across PubMed, Web of Science and Scopus databases. Also, the main Spanish and American deontological codes of physicians and dermatologists have been revised. The authors recommend declaring all conflicts of interest while respecting the patients\' autonomy, confidentiality, and privacy. Cosmetic dermatology, cosmetic selling, artificial intelligence, tele-dermatology, and social media are feasible as long as the same standards of conventional dermatology are applied. Nonetheless, the deontological codes associated with these innovations need to be refurbished.

BACKGROUND: Aesthetics medicine, a controversial branch of clinical medicine known for its high degree of commercialization, faces numerous conflicts, particularly in some developing countries. The global aesthetics medicine industry requires enhancements of its legal and supervision framework and risk management systems.
OBJECTIVE: This paper aimed to provide a comprehensive visual analysis of academic achievements related to regulatory and legal issues in the field of aesthetic medicine and to identify its development trends and research hotspots.
METHODS: The Web of Science Core Collection was employed to retrieve relevant studies, resulting in a total of 602 research articles after selection. Utilizing bibliometric methods and CiteSpace, this study analyzed the primary countries, institutions, authors, journals, hotspots, frontiers, and trends in this domain.
RESULTS: The findings indicated rapid increases in the number of published papers. The United States emerged as the leading contributor with 131 research papers and the highest intermediate centrality. Eleven keyword clusters were identified, with \"adolescence\" and \"office-based surgery\" being the most recent topics. We also analyzed the trends and frontiers of legal research in medical aesthetics.
CONCLUSIONS: The importance of informed consent has been increasingly emphasized, and research in the field of medical aesthetics has been gradually expanding beyond individual cosmetic procedures. The management system has become more comprehensive, moreover, guidelines and medical laws have been continually published, with research shifting toward a holistic perspective that encompasses patients, medical aesthetic providers, and regulatory authorities in the study of medical aesthetics regulation and legislation. This paper also proposes some innovative directions for future research and applications.

BACKGROUND: The integration of artificial intelligence (AI) into cosmetic medicine promises to revolutionize the field by enhancing diagnosis, treatment planning, and patient care.
OBJECTIVE: This manuscript explores the current adoption and perceptions of AI among professionals in the realm of cosmetic dermatology and plastic surgery, utilizing insights from the IMCAS Congress 2024 attendees.
METHODS: A survey employing a digital questionnaire with 14 questions was distributed among attendees of the IMCAS Congress 2024 to evaluate their familiarity with AI, usage in clinical practice, perceived advantages, and concerns regarding data privacy and security.
RESULTS: The survey revealed that a majority of respondents are familiar with AI\'s potential in cosmetic medicine, yet there is a notable discrepancy between awareness and actual application in practice. Concerns over data privacy and a pronounced need for further training were also highlighted.
CONCLUSIONS: Despite recognizing AI\'s benefits in cosmetic medicine, significant barriers such as data privacy concerns and the need for more comprehensive training resources must be addressed. Enhancing education on AI-applications and developing strategies to mitigate privacy risks are imperative for leveraging AI\'s full potential in improving patient care and outcome in cosmetic medicine.

BACKGROUND: Throughout the last decade, a notable increase in HA-filler-related complications have been observed, owing to the increase in demand for filler injections and availability of multiple products.
OBJECTIVE: The aim is to provide practical advice on the best way to prevent and treat HA-filler-related complications.
METHODS: Thirty patients who experienced visible and/or symptomatic complications localized within the facial area were treated according to our algorithm. Patients with inflammatory lesions underwent antibiotic and anti-inflammatory therapy, followed by hyaluronidase injections. Patients with abscesses were treated with antibiotics, incision, and drainage. Each patient completed the dermatology-specific quality of life questionnaire (DLQI) at the first and last examinations.
RESULTS: Among the 29 patients who received antibiotic therapy, 3 healed without further treatment. However, 18 received hyaluronidase injections, 9 underwent incision and drainage, and 5 presented with fistulas and developed retracted scars. Moreover, 80% of the patients were completely healed, 13% significantly improved, and 3% did not show any improvement. The DLQI scores analysis showed a notable impact of patients\' diseases on their quality of life, mainly in the terms of personal relationships and symptoms, with minor impacts on intimate relationships, ability to work, and study. We demonstrated that our algorithm resulted in a significant improvement in the overall quality of life at the last follow-up (p < 0.001).
CONCLUSIONS: The use of filler injections requires caution and specific training because they can lead to serious complications. If these complications are recognized promptly, healing can be optimized. Our treatment algorithm demonstrated high rate of healing and significant improvement in the patients\' quality of life.

OBJECTIVE: To explore the concept of, ethics surrounding, and arguments for and against cosmetic psychiatry.
CONCLUSIONS: Cosmetic psychiatry may be defined as the science and practice of interventions that subjectively enhance the mental states of healthy people. Cosmetic medicine (including surgery) is a professionally and socially accepted part of contemporary medical practice; cosmetic psychiatry is not. Like cosmetic medicine, there are significant risks associated with cosmetic psychiatry. There is an urgent need for a broader conversation about this emerging clinical reality.

Background: Few studies have evaluated patients\' motivations for seeking minimally invasive cosmetic procedures. Objective: This study aimed to assess the demographic characteristics and motivation of patients who seek minimally invasive cosmetic procedures in two academic referral dermatology centers. Methods: The study included adult patients seeking minimally invasive facial cosmetic procedures at two academic dermatology centers in Tehran, Iran, between January 2019 and June 2019. Results: The majority of patients were married, employed women with a mean age of 39.6 ± 10.74 years. The most common region of the face they expected to change was the eyes (56%). Patients who requested fillers desired their cheeks to improve significantly more than patients who requested toxin injections (20.5% vs. 3%; p = .005). Patients had mostly heard about the procedures from friends (40.4%). Approximately one third of patients had experienced a major life event during the preceding year (loss of a family member [50%], marriage [26.9%]). A minority of patients had ever visited a psychiatrist (13.9%), and 15.3% had a history of using psychiatric drugs. The procedure type requested by men was significantly different from that requested by women (88.2% vs. 60.8 % for Botox; 11.8% vs. 34.9% for fillers, and 0% vs. 4.3 % for fat injections; p = .044). The most common motivating factor for patients was gaining rejuvenation (39.2%). The most common preventive factors for patients to undergo the procedures earlier were financial issues (41.7%). Conclusion: Patients seeking minimally invasive cosmetic procedures were married, educated, employed women in their 30s desiring rejuvenation and commonly were not influenced by external factors, such as relationships or the media.

BACKGROUND: Topical anesthesia is widely used in many dermatological and cosmetic procedures. Nevertheless, the stratum corneum serves as the skin barrier, impedes the transdermal drug delivery greatly, and results in insufficient analgesia. Cold atmospheric plasma (CAP) has been researched as a transdermal drug delivery promoter with ex vivo experiments for a few years, while clinical trials are scarce.
OBJECTIVE: To assess the efficacy and safety of CAP as a pretreatment to improve the transdermal absorption of topical anesthetic cream before the CO2 laser treatment for postacne scars in the human body.
METHODS: Twenty patients, seeking full facial laser treatment for atrophic acne scars, underwent a randomized split-face study. One side of the face was pretreated by CAP before topical anesthetic cream was applied, and the other side was applied with topical anesthetic cream only as control. After that, the subjects went through full-face fractional CO2 laser treatment of postacne scars. They were asked to score the pain on a visual analogue scale (VAS) after the laser treatment to measure the anesthesia effects which indicates the transdermal absorption of the cream. Possible adverse effects of the plasma were recorded during the pretreatment including associated pain, heat, erythema, and edema.
RESULTS: The VAS score of the treated side was statistically lower (5.1 ± 2.1) compared with the nontreated side (6.3 ± 1.9), with a mean difference of 1.3 (95% confidence interval [CI], 0.6-1.9; P < .0001). No severe adverse event was reported, and all the disturbing sensations and symptoms (pain, heat, and edema) were evaluated as mild with no mean score surpassing 4.0.
CONCLUSIONS: Plasma pretreatment of 5 minutes before topical anesthetic cream application gives significant pain reduction during the laser procedures, showing the potential effects of CAP on promoting transdermal drug delivery, with no obvious adverse effects reported.
