Comparative physical properties of hyaluronic acid dermal fillers.
BACKGROUND Hyaluronic acid (HA) fillers are becoming the material of choice for use in cosmetic soft tissue and dermal correction. HA fillers appear to be similar, but their physical characteristics can be quite different. These differences have the potential to affect the ability of the physician to provide the patient with a natural and enduring result. OBJECTIVE The objective of this artic...
متن کاملRheological properties of cross-linked hyaluronic acid dermal fillers.
AIM Ha based dermal fillers in recent years aroused big interest in the area of cosmetic surgery for the rejuvenation of the dermis. There is not a ideal dermal filler (DF) for all applications and in commerce there are many types of DF that differ for their chemical-physical properties. So the aim of this paper is to correlate the rheological and physical properties of different DF to their cl...
متن کاملDermal fillers and combinations of fillers for facial rejuvenation.
Until recently, the use of dermal fillers was limited in the United States by the small number of products approved by the Food and Drug Administration. The products now approved for use in the United States have opened up the range of possibilities for combinations of products that are synergistic in their effects. Combinations of products may be discussed in temporal or anatomic relationships...
متن کاملSelenium nanoparticles inclusion into chitosan hydrogels act as a chemical inducer for differentiation of PC12 cells into neuronal cells
Background and Objective: Biomaterials and nanomaterials have generated a great opportunity in regenerative medicine. Neurological disorders can result in permanent and severe derangement in motor and sensory functions. This study was conducted to examine the effects of selenium nanoparticles (Se NPs) as a chemical inducer for differentiation of PC12 cells into sympathetic-like neurons characte...
متن کاملStructural, mechanical and osmotic properties of injectable hyaluronan-based composite hydrogels.
The osmotic and scattering properties of hyaluronan-based composite hydrogels composed of stiff biopolymer chains (carboxymethylated thiolated hyaluronan (CMHA-S)) crosslinked by a flexible polymer (polyethylene glycol diacrylate (PEGDA)) are investigated and analyzed in terms of the scaling theory. The total pre-gel polymer weight concentration is varied between 0.5 wt.% and 3.2 wt.%, while th...
