RESUMEN
INTRODUCTION: Hand aging is a prevalent concern characterized by the atrophy of local soft tissues and increased visibility of vessels and tendons. Hyaluronic acid (HA) and calcium hydroxyapatite (CaHA) are well-established treatments for addressing this issue. While hybrid filler containing HA and CaHA has been proposed for facial rejuvenation, studies investigating its efficacy for hand rejuvenation are lacking. OBJECTIVE: This study aims to assess the safety and efficacy of a premixed hybrid filler containing calcium hydroxyapatite (CaHA) and hyaluronic acid (HA) for hand rejuvenation. METHODS: A prospective, double-blind, controlled trial was conducted. The control arm (CA) received conventional subdermal treatment with CaHA at a 1:1 dilution. The intervention arm (IA) underwent hybrid treatment, consisting of CaHA at a 1:1 dilution combined with 1 ml of low-density HA. Evaluation was performed subjectively using the Global Aesthetic Improvement Scale (GAIS) and the Manchester Hand Grading System (MHGS), and objectively using cutometry, corneometry, and ultrasound. RESULTS: Both the CA and the IA exhibited high rates of patient satisfaction and satisfaction as assessed by blinded evaluators. Although numerical superiority was observed in the IA, no statistical difference was found between the two groups. Significant improvements in hydration, elasticity, and skin thickness were observed in both arms, with no discernible difference between them. Greater ultrasound echogenicity was noted in the IA, which, as indicated by existing literature, may suggest enhanced biostimulation. No adverse effects were reported in either arm. CONCLUSION: Premixed filler containing HA and CaHA for hand rejuvenation appears to be a safe and effective approach.

BACKGROUND: Classic nasal hump reduction based on partial resection of the cartilage and bones in the nose may lead to dorsum deformities such as an inverted-V deformity, irregularities, and an open roof. Techniques that preserve the nasal dorsum (namely the push-down and let-down) avoid these problems, but may not always be indicated for very large, broad, or deviated noses, whereas cartilaginous push-down is also indicated for large and deviated humps. Because only the cartilaginous portion of the hump is preserved in the cartilaginous push-down, a rough area may remain where the bony portion is resected. OBJECTIVES: The aim of this study was to develop a variation of the cartilaginous push-down technique which includes a bony cap to preserve the smoothness of the keystone area during nasal hump treatment. METHODS: Forty-eight consecutive patients with indication for nasal hump treatment who underwent cartilaginous push-down procedures with bony cap preservation between August 2018 and October 2019 were studied. RESULTS: We observed related complications in 2 patients (4.2%); in 1 patient (2.1%) the bony cap was lost during the rasping of the nasal bones and the surgery was altered to utilize only the cartilaginous push-down. Another patient (2.1%) experienced a mild hump recurrence during the early weeks following the procedure. All of the remaining patients had their nasal humps treated adequately. CONCLUSIONS: The nasal hump was adequately corrected in most of the study patients (95.8%). Preserving the bony cap while performing the cartilaginous push-down may prevent complications related to the osseous resection of the keystone area.

Introduction: Anatomy is one of the foundations in medicine, and choosing a practical and dynamic teaching method is essential for better retention of your learning. The objective is to use facial anatomy applied to live models as an innovative teaching strategy and to evaluate the experience of the learning experience of students assigned to the method. Method: The work analyzes the experience with body painting of 51 students from Instituto Boggio assigned this method (or instructed to use this method) during their classes. Different planes and anatomical structures were represented on live models' faces to simulate and teach the main injectable cosmetic procedures; syringes, needles, cannulas, and ultrasound gel stained with food inks were used. Overlapping latex layers were used for the anatomical study of the temple, middle third of the face, and nose, allowing the reproduction of fillers and biostimulators in these regions. The main muscle groups were represented for the discussion of high-precision botulinum toxin. After the entire demonstration, the students answered a questionnaire via "Google Forms" evaluating the methodology used. Results: According to the answers to the questionnaires, most students considered body painting an innovative methodology that contributed to learning anatomical content and satisfactorily illustrating the demonstrated cosmetic procedures. Conclusion: Practical learning through live models makes this new teaching method something innovative and unique that, in an enjoyable way, enables the study of anatomy and appropriately trains clinical skills.

A percepção da beleza é ainda algo pouco compreendida, apesar de francamente notável. Pessoas consideradas belas notadamente tem melhor autoestima e um melhor desempenho em suas relações interpessoais. A procura por tratamentos cosmiátricos está em franca ascensão e o crescimento entre os homens é ainda maior. A perfeita compreensão das diferenças entre os atributos masculinizantes e feminilizantes em uma face deve ser encorajado, a fim de obter melhores resultados estéticos e a prevenção de estigmas de tratamento. Nesta revisão, será abordada cada região facial, pormenorizando os padrões de beleza de cada gênero, norteando os detalhes do tratamento.
The beauty perception is still poorly understood, though downright remarkable. People considered beautiful notably have better self-esteem and perform better in their interpersonal relationships. Demand for cosmetic treatments is on the rise and growth among men is even higher. Perfect understanding of the differences between masculinizing and feminizing attributes on a face should be encouraged in order to achieve better aesthetic results and the prevention of treatment stigmas. This review will cover each facial region, detailing the beauty standards of each gender, guiding the details of treatment.
RESUMEN
Introdução: a hidroxiapatita de cálcio em gel carreador de carboximetilcelulose apresenta resultados inequívocos para a melhora cutânea facial, estimulando a produção de colágeno e elastina. Seu uso para tratamento corporal tornou-se on- label apenas recentemente, após comprovações científicas de seu benefício em maior diluição. O objetivo deste trabalho foi demonstrar uma padronização técnica para racionalização da aplicação corporal. Neste estudo foram idealizadas figuras vetorizadas para aplicação da hidroxiapatita de cálcio com diluição intermediária. Com a técnica proposta, é possível calcular, com exatidão, o volume de produto necessário para cada paciente em função do tamanho da unidade anatômica a ser tratada e das características topográficas da região. A racionalidade desta técnica permite ainda distribuição homogênea, minimização das complicações por acúmulo de produto, boa tolerabilidade pela paciente e otimização dos resultados. Conclusões: a simplicidade técnica das figuras vetorizadas facilita a aplicação da hidroxiapatita de cálcio, e as customizações devem ser feitas com a maior experiência do injetor.
