Techniques for the administration of injectable fillers and neuromodulators for facial aesthetic rejuvenation and enhancement continue to evolve. As the number of physicians with limited experience in providing aesthetic treatments expands, the need for guidance and training from more experienced injectors has become apparent. The use of a slow, careful, and methodical injection technique is imperative in all treatment settings and for all facial areas. Constant attention to local anatomy, particularly arteries, veins, and nerve bundles, is critical for minimizing complications...

Minimally invasive aesthetic and cosmetic procedures have increased in popularity. Injectable dermal fillers provide soft tissue augmentation, improve facial rejuvenation and wrinkles, and correct tissue defects. To investigate the use of adipose‑derived stem cells integrated with a hyaluronic acid based gel as a dermal filler, the present study used cytotoxicity studies, proliferation studies, adipogenic and osteogenic differentiation, apoptosis assays and scanning electron microscopy. Although hyaluronic acid induced low levels of apoptosis in adipose‑derived stem cells, its significantly promoted proliferation of adipose‑derived stem cells...

To correct skin imperfections, aesthetic medicine today makes use of injectable dermal fillers that allow filling skin by increasing the volume of soft tissue. Currently, there are many fillers usable for their excellent biocompatibility and low allergic reactions that ensure good results and good compliance. Among these, the most widely used filler is Human Plasma, obtained by centrifugation from patient blood and processed through cycles of centrifugation and heating, until it becomes a gel. In this work, we evaluated the effect of the Plasma on fibroblasts behavior in terms of cell viability, survival, growth and collagen production...

INTRODUCTION: The appeal of hyaluronic acid fillers for facial soft tissue augmentation is attributable to both an immediate aesthetic effect and relatively short recovery time. Although recovery time is an important posttreatment variable, as it impacts comfort with appearance and perceived treatment benefit, it is not routinely evaluated. Natural-looking aesthetic outcomes are also a primary concern for many patients. MATERIALS AND METHODS: A single-center, noncomparative study evaluated the time (in hours) until subjects return to social engagement (RtSE) following correction of moderate and severe nasolabial folds (NLFs) with RR (Restylane(®) Refyne)(®) and RD (Restylane Defyne), respectively...

For several years, the Réunion des musées nationaux - Grand-Palais has produced polyester resin reproductions in order to replace marble sculptures that have weakened by outdoor exposure. These objects are made of a complex multilayered polyester composite material including reinforcements to ensure the mechanical strength of the final structure and mineral fillers that allow to imitate the original aesthetics. However, the final structure also weakens because of constant outdoor exposure and ageing. This observation leads today to conduct research related to the structural health monitoring of reproductions for preventive conservation of cultural heritage...

BACKGROUND: Fat grafting has emerged as a reference procedure in daily plastic surgery practice. Unpredictable fat resorption is the main clinical problem. For this purpose, the addition of PRP to enhance fat revascularization is now an easy and popular procedure. However, no consensus exists regarding the respective volume of fat and PRP used to obtain the ideal mixture. This study investigated the rheological properties of microfat mixed with different proportions of PRP. Results obtained were compared with commercialized hyaluronic acid fillers...

Soft tissue augmentation by fillers has become a popular cosmetic tool to offer rejuvenation and aesthetic improvement. Its results are comparable to those previously achieved only by plastic surgery. However, marked increase of filler procedures is associated with a great number of complications. Complications associated with filler injection might have early onset (within days) or late onset (after weeks to years). Delayed complications include infections, foreign body granulomatous reaction, migration of filler material, persistent discoloration, and scarring...

INTRODUCTION: Acrylic resins have been used extensively for the fabrication of denture bases because of their aesthetic qualities, ease of manipulation and repairability. Flexural fatigue of the denture base has been shown to be a factor in the clinical failure of polymethyl methacrylate resin dentures. Also, the fracture can result from impact, fatigue or degradation of the base material. Hence, there is a need to increase the strength of denture base resins. AIM: To evaluate the effect of reinforcing alumina oxide filler on the flexural strength of different acrylic resins...

Demand for non-surgical rejuvenating procedure is constantly increasing due to the aging population, increasing expense of aesthetics and beauty procedures, introduction of new applications and rising demand for noninvasive aesthetic procedures over surgical procedures. Skin necrosis is a rare but severe potential complication. It is caused by impediment of the blood supply to the skin area by compression and/or obstruction of the vessel with filler material, and/or direct injury to the vessel. We report the case of a young patient who presented an acute and severe complication after a dermal filler injection by an unlicensed therapist...

OBJECTIVE: The use of autologous fat as a soft tissue filler has increased over the past decade in both reconstructive and aesthetic surgeries. Enhancement of autologous fat grafts with the addition of the stromal vascular fraction (SVF) has been reported to improve long-term volume retention. Stromal vascular fraction is most commonly isolated using enzymatic digestion, but it is unknown what effect the digestion process has on the adipocytes and SVF cells that comprise the graft. Some clinicians have reported use of enzymatically digested fat grafts to alter the physical properties of the tissue in specialized applications...
