BACKGROUND: With the number of available dermal fillers increasing, so is the demand for scientifically based comparisons, often with rheological properties in focus. Since analytical results are always influenced by instrument settings, consensus on settings is essential to make comparison of results from different investigators more useful. OBJECTIVE: Preferred measurement settings for rheological analysis of hyaluronic acid (HA) fillers are suggested, and the reasoning behind the choices is presented by demonstrating the effect of different measurement settings on select commercial HA fillers...

Injectable substances known as fillers are used to palliate age-related atrophy and ptosis, and for their so-called "pseudo-lifting" action. They do not replace face and neck lift, but allow it to be postponed or, when injected after surgical lifting, make the result durable. Hyaluronic acid has a predominant and unchallenged place among fillers, well ahead of poly-L-lactic acid or calcium hydroxyapatite. Approaches and injection methods are the same for all fillers, corresponding to those for autologous fat injection, the reference substance, with a few particularities...

The recent global consensus on the management of cosmetic aesthetic injectable complications from hyaluronic acid (HA) has increased the focus on the use of hyaluronidase more than ever before (M. Signorini et al., 2016). A comprehensive knowledge of facial anatomy, including structural positioning of facial arteries and veins, and an extensive knowledge of HA products available for injection procedures, combined with best practice protocols, will assist to prevent adverse events. Despite the growing number of patients using cosmetic fillers for facial restoration, the incidents incidence of adverse events remains low...

This third article of a three-part series addresses techniques and recommendations for aesthetic treatment of the lower face. The lower face is considered an advanced area for facial aesthetic treatment. In this region, soft-tissue fillers play a more important role than neuromodulators and should be used first to provide structure and support before neuromodulators are considered for treatment of dynamic lines. Treatment of the lip, perioral region, and chin, in addition to maintaining balance of the lower face with the face overall, is challenging...

A 72-year-old Caucasian female presented for evaluation of bilateral lower eyelid "fluid filled" bags that had been present and slowly worsening for 7 years. She reported a history of lower eyelid blepharoplasty in her 40s, as well as hyaluronic acid tear trough fillers 8 years prior to presentation. Her malar edema completely resolved following injection of hyaluronidase. To our knowledge, this is the longest reported interval for presentation and treatment of hyaluronic acid associated malar edema.

Hydrogels have emerged as a highly interdisciplinary topic as they play a significant role for a vast number of applications. They have been studied extensively as materials for contact lenses, wound dressing and as filler material in soft-tissue augmentation, in which classical polymer backbones such as hydroxyethylmethacrylate (HEMA) are typically employed. More recently, polysaccharides have received attention, particularly in the fields of regenerative medicine and tissue engineering, as ideal candidate materials for artificial extracellular matrices (ECM)...

In addition to cosmetic use, filler materials are frequently employed for reconstruction of contour defects. Scars and tissue defects after accidents, surgery and irradiation are also ideal indications for injectables. The ideal filler should be easy to inject, easy to form, and should remain in the body as long as possible. It should neither be allergenic or carcinogenic nor susceptible to infections or biofilms, but still potentially reversible, temperature-stable, and cheap. There is still no augmentation material that fulfils all of these criteria...

INTRODUCTION: Cosmetic injections of dermal fillers or fat could cause ophthalmic artery embolism and even blindness, the high-risk regions of which are considered glabellar, nasal dorsum, and nasolabial fold. Understanding anatomy of the related arteries is important for a physician to safely perform filler injections. To investigate the mechanisms of ophthalmic artery embolism following the injections, cadaver anatomy was studied. METHODS: Ophthalmic artery, facial artery, their branches, and anastomoses among them were anatomized in 12 fresh cadavers...

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...
