Injectable dermal fillers continue to increase in popularity in aesthetic medicine. Although rare, vision loss secondary to filler injections is a devastating complication associated with a poor visual prognosis. The mechanism for vision loss is thought to be related to retrograde embolization of the dermal filler from peripheral vessels in the face into the ophthalmic arterial system. Early recognition and prompt management are essential if vision is to be salvaged. The use of retrobulbar hyaluronidase is still contentious, however when administered by a specialist, this treatment gives the best chance at visual recovery and should be considered for all cases.

Background: Hollowness in the anteromedial, buccal, and lateral cheek regions is a common concern in aesthetic medicine, often resulting from age-related volume loss and structural changes. Advanced filler injection techniques that incorporate a thorough understanding of facial anatomy are critical for achieving optimal and safe outcomes.
Objective: To review and detail anatomically guided filler injection techniques for addressing hollowness in specific cheek regions, considering facial anatomy, ethnic variations, and patient-specific aesthetic goals.
The Restylane® portfolio of hyaluronic acid (HA) fillers comprises a broad range of products, each with a unique combination of gel strength/firmness and flexibility. Restylane® Shaype™ (HASHA) is a new HA injectable produced with NASHA-HD™ technology and the most recent addition to the Restylane portfolio. NASHA-HD is an evolution of the NASHA™ platform that adds more HA and uses a more efficient cross-linking even though the degree of modification is kept low.

This study evaluates two biostimulatory agents' effects on genes, expressed proteins, and respective pathways as potential aging biomarkers and treatment outcomes.
Methods: This 13-week, randomized, single-center, comparative study compared volume change and gene expression stimulated by poly-L-lactic acid (PLLA-SCATM) and calcium hydroxylapatite (CaHA-R) via punch biopsy in the nasolabial fold (NLF).
Background: Delayed reactions to hyaluronic acid (HA) fillers have been reported following various immunologic and infectious triggers.
Aim: Herein, we describe cases of delayed immunologic reactions (DIRs) following HA-soft tissue augmentation fillers precipitated by triggers not previously described in the literature. Patients: Case 1 describes a 57-year-old female with DIR to HA-filler following a motor vehicle accident in the marionette lines and nasolabial folds.

Localized inflammatory reactions in patients with past procedural history of intradermal injections can quickly drive the clinician's attention towards a diagnosis of soft-tissue infection in the context of symptoms such as fever, malaise, and local induration of the adipose panniculus. However, in patients with a long-term history of granulomatous events, a rheumatologic approach must be taken into consideration when the clinical course overwhelms the odds for more conventional diagnoses. In this case, a 39-year-old female patient who underwent bilateral lower limbs intradermal filllers presented with a two-year clinical course of repetitive flares of external bilateral hip tenderness, pain that limits her walking, soft-tissue nodular inflammation, redness, fever and a soft mobile nonpainful right supraclavicular lymphadenopathy.
