Abstract Aim : Over the last 15 years, hyaluronic acid (HA) fillers have become the most popular injectable biomaterial for soft tissue correction. With the increasing number of available HA fillers and the multiplication of facial treatments all over the world, there has been a need from physicians to better understand the HA fillers science. There is especially a growing interest in the science-based evaluation of rheological characteristics which represents an essential tool to guide physicians in the selection of the most appropriate HA fillers, administration techniques and depths of injection for their clinical applications.

Methods : Four key rheological parameters (viscosity η , elasticity G’, normal force F N and elasticity E’) are measured and discussed on five HA fillers.

Results : These four key rheological parameters are demonstrated to play a pivotal role, in combination with the cohesivity, for better predicting the clinical behavior of HA fillers at different stages of their lifetime.

Conclusion : This article discusses the importance of four key rheological parameters during the main steps of the clinical HA fillers’ lifetime, from the product injection to the loss of clinical effects. A better knowledge of these HA fillers’ rheological parameters can help the physicians to optimize their aesthetic outcomes, safety and patient satisfaction.

Abstract Aim : Hyaluronic acid (HA) is considered as the gold standard biomaterial for facial soft tissue correction. Over the last 8 years, there has been a strong demand from physicians for HA products with high projection capacity to restore facial volume loss at the level of the cheeks, cheekbones, chin, temples and jawlines. The projection capacity is thus an essential property for HA fillers especially for the products dedicated to the restoration of the volume of the face.

Methods : In this publication, a new skin model assay for evaluating the projection capacity of HA fillers is presented, applied and discussed.

Results : This skin model assay enables to efficiently assess the projection capacity of a HA filler product. The comparative evaluation of a product benefiting from the novel OXIFREE technology and Juvéderm Voluma shows a higher projection capacity for the OXIFREE product than for Juvéderm Voluma.

Conclusion : This assay is demonstrated to be a key tool to guide physicians in the selection of products with high ability of tissue projection to optimize their aesthetic outcomes when they need to create facial volume.

Abstract Introduction: The principal author was given the opportunity to assess new hyaluronic acid filler, first before its European Commission labeling during clinical investigations in France, and then after its European Commission labeling in his clinical practice in Geneva, Switzerland. This hyaluronic acid gel benefits from the world’s first patented OxiFree™ technology. This article sought to present preliminary safety and efficacy data from the first private patient series treated in Geneva with this cross-linked hyaluronic acid gel, called MaiLi. Material and methods: Like most of its competitors, MaiLi is available in various variants, including gel for filling fine wrinkles, for deeper wrinkles, folds, and for lip enhancement, in addition to gels for volumizing indications. This cohort study encompassed patients from the authors’ private esthetic clientele in Geneva, Switzerland. Depending on the indications, the injections were performed according to previously described techniques, ranging from the “blanching technique” to deeper injections. Results: Between January and November 2021, overall 45 patients aged 56 years on average were injected MaiLi gels, according to the areas they wished to be treated, with a follow-up period ranging from a few days to 12 months. Based on our current dataset, we confirm that MaiLi fillers have proven very safe, causing no unexpected undesirable effects. The gel’s hold over time related to its remarkable projection capacity was excellent, resulting in quite natural outcomes and a perfect integration into the tissues. These beneficial effects were still evident at 1-year follow-up. Conclusion: The MaiLi hyaluronic acid fillers proved to be well tolerated and safe, with long-lasting effects. Remarkable properties revealed in this follow-up were their projection capacity and suppleness, as well as their ease of use and longevity, resulting in full patient satisfaction. No relevant undesirable effects were observed. There were no edematous reactions following the injections, nor were there any lymphatic circulation disorders.

Introduction The first injectable wrinkle fillers date back to 1980-1981, when bovine collagen was employed, following their approval by the American Food and Drug Administration as cosmetic drugs [1]. Given that natural Hyaluronic Acid (HA) undergoes extremely rapid turn-over within the skin, commercially available HAs needed to be cross-linked using different manufacturing techniques, resulting in products that still widely vary in formulation and cross-linking degree. Among the HAs manufactured with proprietary technologies associated with specific rheological properties, the first author already employed in the year 1994 HA prefilled syringes based on Non- Animal Stabilized Hyaluronic Acid (NASHA™, Galderma Pharma S.A., Lausanne, Switzerland) technology [2]. The first papers reporting the results obtained on subjects treated with HA gels were dated around 1998 [3,4]. Since then, numerous HA fillers have constantly been developed. Consequently, many

more brands and formulations were manufactured, some of which presenting excellent results, whereas others were less effective [5,6]. In the author’s view, several HA fillers had to be only slightly modified to drastically improve their viscoelastic properties. Moreover, lidocaine was added to certain gels, which could markedly alter the gels’ viscoelastic properties compared to their formulation without any anesthetic, as previously observed [7-9]. Recently, a novel proprietary manufacturing technology for producing innovative HA fillers was elaborated, reference being here made to MaiLi’s OxiFree™ technology (Kylane Laboratoires S.A., Plan- les-Ouates, Switzerland). This new HA filler was launched by Sinclair Pharma under the name of MaiLi. Its basic principle consists in the cross-linking of the HA under inert atmosphere and the extraction of reactive oxygen upon the manufacturing process. This procedure was primarily designed to significantly preserve the intrinsic properties of the high-molecular-weight HA chains. Based on this new technology,

Due to the development of highly sophisticated fillers with radically different rheological properties and innovating techniques, it has become possible to correct specific regions with more natural results than before. This four-center pilot study sought to investigate the efficacy and safety of MaiLi® Precise in correcting fine-line wrinkles of the perioral area. Material and Methods: MaiLi® Precise is a recently introduced Hyaluronic Acid (HA) filler, harnessing the OxiFree ™ technology, for suppleness, flexibility, and high longevity. These properties were deemed particularly suitable for correcting fine-line perioral wrinkles. All injections were performed using intradermal injections, with the fluid HA injected in a very superficial manner, resulting in the formation of very small papules at the wrinkle, disappearing within 1-2 hours. Follow-up occurred at one (T1) and three months (T2) post-injection. Treatment effectiveness was evaluated using the Global Aesthetic Improvement Scale (GAIS), as was the satisfaction of the subjects and investigators. Adverse Events (AEs) were also reported. Results: Overall, 20 patients aged 56 years on average, from four centers, were injected MaiLi® Precise into the perioral area to correct perioral lines using intradermal injections. No specific safety concerns were detected, given that AEs remained mild, were almost all resolved by T1, and were completely absent by T2. Patient and physician satisfaction were both >90% during follow-up. All physicians attributed improved, much improved, or very much improved GAIS scores at T1 and T2, indicating a marked improvement in appearance after injection. Conclusion: Based on the current study results, MaiLi® Precise was shown to be safe and provided satisfactory results from both the patient and the physician’s points of view during a 3-month follow-up.

Introduction The perioral region refers to the lower one-third of the face, which comprises the upper and lower lips, the cheek-lip grooves or nasolabial folds, and the chin. Ageing signs at this region are among the key reasons for patients seeking treatment [1]. Indeed, this region undergoes significant changes during ageing that likely contribute to a “displeased” or “sad” expression [2]. These changes include fine wrinkling around the lips, deep nasolabial and mentolabial folds, elongation and flattening of the upper lip, downturned corners of the mouth, marionette lines, as well as chin irregularities. The perioral region is the most concerned area for facial rejuvenation. Different options exist, Hyaluronic Acids (HAs) being commonly

used [3]. Since 1998, revolumization of facial structures using HA dermal fillers has been instrumental in reducing signs of ageing and increasing attractiveness [4-6]. In the following years, many different HA filler brands and formulations were manufactured, with differing viscoelastic properties [7,8]. Lidocaine was added to certain gels to increase patient compliance [9]. This perioral region remains one of the most difficult areas to treat, owing to its highly dynamic nature. Wrinkles within the cutaneous lip areas range from fine, almost imperceptible lines to multiple deep etchings, generally referred to as barcodes. Previous attempts of correcting these areas with fillers showed that subcutaneous ridges or overcorrection may be generated in relation with the rheological properties of previous HA fillers [10].
