With increasing use of dermal fillers, more and more adverse effects are reported. The most devastating one is intravascular injection. We propose a novel needle prototype that allows physicians to prevent intravascular injection.

The treatment options for facial rejuvenation using dermatological, nonsurgical techniques have dramatically increased in the past 10 years. This follows the introduction of botulinum toxin and a variety of dermal fillers. The public interest in noninvasive treatments has changed the market beyond recognition with more physicians involved in providing services to satiate the demand. The impact ...

BACKGROUND A new family of next-generation non-animal hyaluronic acid (HA) dermal fillers was approved by the FDA in June 2006. Compared with other HA fillers available in the United States at the time of writing, these new fillers have a higher concentration of HA, higher concentration of cross-linked HA, and a smooth consistency--which should promote long-lasting corrections and a smooth, nat...

Although only recently introduced, chemically-modified hyaluronic acid dermal fillers have gained widespread acceptance as "redefining" dermal fillers in the fields of dermatology and cosmetic facial surgery. Although hyaluronic acid-based dermal fillers have a low overall incidence of long-term side effects, occasional adverse outcomes, ranging from chronic lymphoplasmacytic inflammatory react...

AIM To describe an early-onset adverse reaction following the injection of facial fillers, and to summarise the current legislation and research regarding cosmetic dermal fillers. To emphasise that dermal fillers should be considered as part of a general dental practitioner's differential diagnosis for lower lip swelling. OBJECTIVES (1) To describe the types of adverse reactions associated wi...

BACKGROUND Hyaluronic acid (HA) dermal biphasic fillers are synthesized for their efficacy in correcting aesthetic defects such as wrinkles, scars and facial contouring defects. The fillers consist of crosslinked HA microspheres suspended in a noncrosslinked HA. To extend the duration of HAs within the dermis and obtain the particle texturing feel, HAs are crosslinked to obtain the suitable mec...

BACKGROUND In Europe, numerous dermal fillers have been utilized for the past decade. A lot of drawbacks have been reported and sometimes, severe complications occurred. OBJECTIVE Our purpose is to report the clinical aspects of the adverse reactions following injections of some of the dermal fillers. Histological aspects of complications are also described. RESULTS Adverse reactions second...

BACKGROUND Hyaluronic acid (HA) formulations are used for aesthetic applications. Different cross-linking technologies result in HA dermal fillers with specific characteristic visco-elastic properties. OBJECTIVE Bio-integration of three CE-marked HA dermal fillers, a cohesive (monophasic) polydensified, a cohesive (monophasic) monodensified and a non-cohesive (biphasic) filler, was analysed w...

Background: Nasolabial folds are natural facial contours that can become more prominent with age, projecting a fatigued or drawn appearance. Reduction of the nasolabial folds is one of the most commonly performed dermal filler treatments. The three classes of dermal fillers currently in use are: Absorbable products, slowly absorbable products and non-absorbable products. Hyaluronic acid product...
