Hyaluronic acid filler can be safely used as a soft-tissue filler for correction of infraorbital hollowing. It has a high overall patient satisfaction profile among patients.
Comparative research on the characteristics of filler products is limited, especially in the preclinical analysis of hyaluronic acid (HA) fillers.
Small-particle hyaluronic acid filler is approved for lip augmentation and correction of perioral rhytides. Treatment with this product may improve facial aesthetics, projected first impression, and self-perception of mood.
Patients seek 3-dimensional volume restoration of the jawline to obtain a "defined" line. Injection of filler into the jawline is not approved by the Food and Drug Administration; however, dermatologists have injected this area with positive results, minimal adverse events, and high patient satisfaction.
As the number of patients using dermal filler for face augmentation increases, the number of adverse events associated with injection may increase. Unpredictable repositioning of blood vessels and a more tenuous blood supply in the operated nose may increase the risk of ischemia, necrosis and vascular embolism following the filler injection.
Loss of facial volume and soft-tissue support are common to types of facial aging. Restoration of a youthful appearance relies upon correction of this loss, and can be achieved in various capacities through use of biostimulatory or hyaluronic acids (HA) injectable fillers. Here, the authors discuss the versatility of calcium hydroxylapatite (CaHA) in volume replacement and the applications and facial regions for which CaHA, poly-L-lactic acid (PLLA), and HA fillers are best suited.
BACKGROUND: The use of blunt-tipped microcannulas for injection of hyaluronic acid (HA) filler in the lip and perioral area has gained popularity as they provide important safety-related advantages compared to traditional hypodermic needles. This study was conducted to assess the safety and effectiveness associated with the use of a blunt-tipped microcannula for lip augmentation and correction of perioral rhytids using a small-particle, hyaluronic acid gel plus lidocaine (SPHAL). METHODS: A multi-center, op...
The clinical performance of fillers in soft tissue augmentation depends upon their physiochemical properties, anatomical areas injected, interaction with the recipient, and the skill and experience of the physician. Scientific measures of filler properties facilitate appropriate selection of treatments for optimal treatment outcomes, and inform adjustments to treatments that improve patient safety and aesthetic outcomes. The rheological properties of calcium hydroxylapatite (CaHA), elastic modulus (G') and ...
In the present study, culture conditions of Streptococcus equi was optimized through Box-Behnken experimental design for hyaluronic acid production. About 0.87 gL of hyaluronic acid was produced under the determined conditions and optimal conditions were found as 38.42 °C, 24 hr and 250 rpm. The validity and practicability of this statistical optimization strategy were confirmed relation between predicted and experimental values. The hyaluronic acid obtained under optimal conditions was characteriz...
An unfortunate consequence of severe acne is scarring, which can have serious psychosocial consequences. Available methods for treating acne scars have varying degrees of effectiveness.
Soft tissue fillers manufactured with hyaluronic acid (HA) dominate the filler market around the world and the fact that HA can be dissolved using hyaluronidase contributes to its popularity. Degradation of cross-linked HA products can be performed in situ and access to hyaluronidase is therefore essential for health care professionals (HCP) to perform safe filler treatments. The aim of the present study was to develop an in vivo model where hyaluronidase degradation of HA fillers can be studied in a standa...
The authors herein describe a case of orbital and ocular ischemic syndrome with blindness after cosmetic hyaluronic acid filler injection. Orbital function, but not visual function, returned after treatment with orbital hyaluronidase and corticosteroids.
Most target areas for facial volumization procedures relate to the anatomical location of the facial or ophthalmic artery. Occasionally, inadvertent injection of hyaluronic acid (HA) filler into the arterial circulation occurs, and unrecognised, is irreparably associated with disastrous vascular complications.Of note, the site of complications, irrespective of the injection site, is similar, and falls into only 5 areas of the face, all within the functional angiosome of the facial or ophthalmic artery.
There are scarce studies in the literature about hyaluronic acid in systemic autoimmune myopathies.
Hyaluronic acid fillers have become popular soft tissue filler augmentation agents over the past several years. Q.O.Fill (JW Pharmaceutical Co., Ltd., Seoul, Korea) is a newly developed soft tissue augmentation agent using Tissuefill (hyaluronic acid derivatives) mixed with platelet-rich plasma (PRP). The purposes of this study were to describe the Q.O.Fill method and evaluate the outcome of face augmentation.
Facial treatments with dermal fillers for medical or esthetic purposes occasionally give rise to adverse effects, ranging from temporary effects such as reddening of the skin, to long term effects such as hardening of tissue. There appears to be a relationship between the lifetime of the filler product and the risk for adverse effects. The lifetime of hyaluronic acid-based fillers is dependent on the presence and amount of crosslinking agents such as 1,4-butanediol diglycidyl ether (BDDE). It would therefor...
Cosmetic facial filler-related central retinal artery occlusion (CRAO) is a devastating complication of facial hyaluronic acid (HA) injection and can be managed by intra-arterial thrombolytic therapy (IATT). The authors report on a 20-year-old woman who developed unilateral CRAO due to facial HA injection and who, despite prompt IATT, lost vision. A review of the related literature found 14 other female patients who developed cosmetic facial filler-related CRAO and accepted IATT management. In no case was v...
Fibrin and hyaluronic acid are important components of the provisional wound matrix. Through interactions with fibroblasts, they provide biophysical cues that regulate the viscoelastic properties of the extracellular matrix. To understand the roles of fibrin and hyaluronic acid in a collagenous environment, we used fibroblast populated collagen lattices (collagen, collagen-fibrin, and collagen-hyaluronic acid). Compared with collagen and collagen-hyaluronic acid cultures, collagen-fibrin cultures showed les...
Over a 74-month period (∼6 years), 143 lower-extremity osteomyelitis locations in 125 patients were treated with a calcium sulfate/hydroxyapatite liquid bone void filler with antibiotic(s).
Hyaluronic acid surface modified liposomes prepared via orthogonal aminoxy coupling: synthesis of nontoxic aminoxylipids based on symmetrically α-branched fatty acids, preparation of liposomes by microfluidic mixing and targeting to cancer cells expressing CD44.
New synthetic aminoxy lipids are designed and synthesized as building blocks for the formulation of functionalised nanoliposomes by microfluidisation using a NanoAssemblr®. Orthogonal binding of hyaluronic acid onto the outer surface of functionalised nanoliposomes via aminoxy coupling (N-oxy ligation) is achieved at hemiacetal function of hyaluronic acid and the structure of hyaluronic acid-liposomes is visualised by transmission electron microscopy and cryo- transmission electron microscopy. Observed str...
BACKGROUND: Although non-surgical treatment options for facial rejuvenation are well-established, the literature remains limited regarding the combined effect of topical skin treatment with filler and neurotoxin on patient appearance and satisfaction. The objectives of this study were to assess the impact of a skin rejuvenation therapy in combination with neurotoxin or hyaluronic acid filler injection on skin quality and general aesthetic improvement as well as on short-term self-esteem. METHODS: From 2015 ...
Hyaluronic acid (HA, also known as hyaluronan), is a non-sulfated linear glycosaminoglycan polymer consisting of repeating disaccharide units of d-glucuronic acid and N-acetyl-d-glucosamine abundantly present in the extracellular matrix. The sizes of hyaluronic acid polymers range from 5000 to 20,000,000 Da in vivo, and the functions of HA are largely dictated by its size. Due to its high biocompatibility, HA has been commonly used as soft tissue filler as well as a major component of biomaterial scaffold...
