[PURPOSE] To describe a case of mechanical eye globe penetration resulting in subretinal and vitreous hemorrhages and retinal tear that occurred immediately following a periorbital hyaluronic acid (HA) filler injection, and to outline acute…

[BACKGROUND] The degree of modification (MoD) of hyaluronic acid (HA) fillers reflects the extent of chemical cross-linking of native HA chains. Lower MoD values correspond to reduced cross-linker content and potentially more physiological …

[OBJECTIVE] To summarize contemporary evidence for intra-articular therapies in synovial joint dysfunction-emphasizing temporomandibular joint (TMJ) osteoarthritis-across regenerative (platelet-rich plasma [PRP]/ injectable platelet-rich fi…

Current injectable fillers often suffer from a transient efficacy and insufficient early stage improvement. To address this, we developed a composite dermal filler consisting of hyaluronic acid (HA) and poly-L-lactic acid-methoxypolyethylen…

[BACKGROUND] The definition of health encompasses mental, emotional, and social well-being, rather than simply the absence of disease. As a result, corrective aesthetic treatments are increasingly being viewed as an integral component of ov…

[BACKGROUND] Hyaluronic acid (HA) dermal fillers are widely used as a nonsurgical treatment for facial aging, including nasolabial folds (NLFs). Because demand for convenient aesthetic procedures increases, new HA products require rigorous …

[BACKGROUND] Botulinum toxin type A (BoNT-A) effectively treats dynamic wrinkles but offers limited direct improvement in skin quality. Hyaluronic acid (HA)-based biorevitalization enhances hydration, firmness, and radiance; however, high-q…

[BACKGROUND] The chin is a crucial facial feature for overall attractiveness. Lower third imbalance can lead to signs of premature aging and loss of jawline contour. Effective chin augmentation with hyaluronic acid fillers has been demonstr…

[BACKGROUND] Dermal fillers are a primary treatment for chin retrusion. However, current options have limitations in longevity and biomechanical properties. [OBJECTIVES] The aim of this study was to evaluate the efficacy and safety of a no…

[BACKGROUND] The widespread use of hyaluronic acid (HA) dermal fillers has been accompanied by an increase in vascular complications, including ischemia and cutaneous necrosis. Although uncommon, filler-induced vascular compromise represent…

Vascular adverse events associated with hyaluronic acid (HA) dermal fillers are typically interpreted as being of arterial origin, while venous involvement of the lip remains poorly characterized. The aim of this report is to analyze and up…

[BACKGROUND] Non-surgical genioplasty is one of the best choices in cases of chin retrusion, and it represents a solution for the aesthetic amelioration of facial profile. Recent concerns arose about the risk of bone resorption and vascular…

[INTRODUCTION] Chin contouring and projection represent some of the most frequently requested procedures in aesthetic practice using hyaluronic acid (HA) fillers. Variations in the physicochemical and viscoelastic properties of HA fillers m…

[BACKGROUND] A novel hyaluronic acid (HA) injectable (Restylane Shaype, HA) with high strength/firmness and enhanced HA concentration, optimized for lower face shaping has been developed. [AIMS] This prospective, 8-week, multicenter, post-…

[BACKGROUND] Cell-free fat extract (CEFFE) has shown promising therapeutic effects on osteoarthritis (OA) in preclinical studies, but its clinical role remains unclear. [PURPOSE] To evaluate the safety and efficacy of intra-articular autol…

[INTRODUCTION] Periocular rejuvenation involves surgical removal of excess skin, fat debulking, or transfer, and optionally includes eyelid ptosis repair or lateral canthal resuspension. Periocular injectables have revolutionized these esth…

[BACKGROUND] Supraorbital hollowing from age-related volume loss or post-blepharoplasty overresection causes upper sulcus deflation. Hyaluronic acid (HA) fillers are frequently used in the upper eyelid, but prospective clinical follow-up da…

Hyaluronic acid (HA) fillers are widely used for facial rejuvenation, offering favorable safety outcomes. Although early-onset complications such as lower eyelid edema and tear trough Tyndall effect are well documented, late-onset manifesta…
