Soft-tissue augmentation has gained much popularity in recent years. Hyaluronic acid (HA) based dermal fillers; a non-permanent injectable device, can restore volume loss, fill fine lines and wrinkles and add curves and contours. HA based dermal fillers entered the non-surgical treatment market in the late 1990s, however there is a lack of data and literature comparing the range of products and detailing the complexities of these products and how it relates to tissue performance. Measuring the physico-chemical properties of these dermal fillers provide key parameters to predict their performance after injection into the body. This article reviews the currently reported methods and parameters used to characterize dermal fillers. The review of these methods and data from the literature provides a useful guide to clinicians and injectors in selecting the optimal product suitable for the needs of each patient.

Tear trough deformity (TTD) is a significant cosmetic concern, with current treatments relying primarily on invasive injectable fillers, which are costly and carry risks of complications. Despite the widespread use of hyaluronic acid (HA) in cosmetic applications, its poor dermal permeation has limited the development of effective topical fillers for TTD.This study aim to develop and evaluate a novel hyaluronic acid nanogel (nanofiller, NF) as a non-invasive topical filler for TTD.

Aim: To present three cases of filler-induced alopecia (FIA) and summarize the current knowledge of its clinical features, mechanisms and treatments.
Methods: In the first two cases, two females developed well-defined triangular patches of hair loss after hyaluronic acid (HA) injections, and received corticosteriod injections with topical 5% minoxidil. The third case described another female who experienced alopecia areata-like hair loss after autologous fat grafting, and received combined therapies including corticosteriod, 5% minoxidil and microneedling.

As the face ages, the skin, fat, muscle, and fascia descend, and the underlying bone, cartilage, and teeth may lose mass. Oculofacial aging is a multifactorial process that is influenced by genetic, environmental, and lifestyle factors. This review summarizes the patterns of oculofacial aging that are observed across populations, including variations in periorbital hollowing, eyelid ptosis, and skin elasticity.

: The history of facial fillers is very broad, ranging from the use of various materials to modern technologies. Although procedures are considered safe, complications such as skin inflammation, infection, necrosis, or swelling may occur. It is crucial for specialists to be adequately prepared, inform patients how to prepare for corrective procedures, adhere to high safety standards, and continually educate.

Introduction: Enlarged facial pores are a common cosmetic concern caused by excessive sebum production, visible hair shafts, and a reduction in skin elasticity, leading to a decrease in skin quality and overall appearance. Various treatment modalities have been explored to address this issue. This study focuses on the efficacy and safety of combining Onabotulinumtoxin A (OnaBoNT-A) and hyaluronic acid filler (HA filler) to target enlarged facial pores in Asians.
