The heel fat pad plays a crucial role in shock absorption during walking, yet clinical strategies to augment its thickness for height enhancement remain underexplored. This case report presents the novel use of cross-linked hyaluronic acid …

Soft tissue fillers are widely used in cosmetic procedures but carry inherent risks, especially vascular complications like tissue necrosis and vision loss due to retinal ischemia. Recent filler advancements beyond hyaluronic acid increase …

[BACKGROUND] Post-procedural ecchymosis can last up to two weeks and diminish patient satisfaction. Laser-assisted clearance is documented with pulsed-dye devices, but data on 1064-nm picosecond/nanosecond platforms remain sparse. [OBJECTI…

Aging is associated with volume loss in the temporal fat pad and lateral cheek fat, leading to sunken temples and increased facial sagging. This study explores the efficacy of a polycaprolactone (PCL)-based filler (Lafullen, Samyang, Seoul,…

The demand for non-surgical upper body enhancement continues to grow, particularly among men seeking improved muscular definition without the risks of surgery or functional compromise. This case report presents a novel protocol using high G…

[BACKGROUND] The shape and size of ears significantly influence facial aesthetics. In many Asian cultures, lying ears are not perceived favorably in Asian culture, leading individuals to seek surgical interventions to correct this issue. Al…

[BACKGROUND] Clavicular enhancement with hyaluronic acid (HA) fillers has recently emerged as a novel aesthetic procedure designed to improve skeletal definition through a minimally invasive approach. Advances in filler rheology and refined…

Aging lips often appear thin, inverted, and poorly defined due to disproportionate atrophy of deep labial fat and mucosa with relative preservation or increase of superficial fat. Traditional augmentation focused on superficial volumization…

[BACKGROUND] Filler-induced vascular occlusion remains a rare but serious complication in aesthetic medicine, particularly in the lips, where collateral circulation is limited. Polynucleotide (DOT-PN) is a polynucleotide-based medical devic…

[BACKGROUND] Thread lifting is a minimally invasive technique for addressing facial aging and skin laxity. Despite its popularity, it carries risks of complications ranging from minor bruising to severe structural injuries. Comprehensive un…

[BACKGROUND] The nasal ala region significantly affects facial aesthetics and function. Botulinum toxin injections may enhance nasal appearance, but their precise impact on underlying muscles remains unexplored. Understanding the muscular a…

[AIMS] Compensatory masseteric bulging, a newly identified complication, arises from repeated botulinum neurotoxin injections targeting the lower mid-masseter in East Asians. This phenomenon occurs when untreated upper muscle layers hypertr…

Glabellar filler injections are a popular non-surgical approach to address depressions and wrinkles caused by aging, muscle activity, and soft tissue loss. An anatomy-based technique emphasizes understanding the complex structure of the gla…

[BACKGROUND] Platysmal bands contribute to neck ageing and lower-face descent. Although botulinum toxin A (BoNT-A) is approved for this indication, conventional whole-muscle dosing requires many superficial injections with attendant risks. …

The inherent two-dimensional (2D) nature of ultrasonography (US) limits its accuracy in visualizing complex intraoral structures. This proof-of-concept feasibility study introduces a novel approach integrating motion-capture technology and …

[BACKGROUND] Infraorbital hollowness significantly impacts facial aesthetics, contributing to a tired and aged appearance. Traditional treatments, such as fillers and botulinum toxin, can lead to unnatural results. Volumizing threads offer …

This study focuses on anatomically based diagnosis and filler injection techniques for managing perioral wrinkles, which present unique challenges due to complex vascular anatomy and diverse wrinkle types. Key perioral wrinkles include vert…

Nasolabial folds significantly impact facial appearance and are a common aesthetic concern. This article reviews anatomic considerations and filler injection techniques for treating these folds, with a focus on the Korean population. The de…

Forehead filler injections have become a popular nonsurgical approach to enhance facial aesthetics by correcting volume deficiencies and improving contours. This anatomy-based approach emphasizes the importance of understanding the complex …

Bruising after cosmetic procedures, such as botulinum toxin injections or dermal fillers, is a frequent complication. We present a new, detailed protocol using different types of lasers at various stages of bruise progression to optimize tr…

[INTRODUCTION] Botulinum toxin injections, commonly used for wrinkle reduction, have been found to improve skin quality, including elasticity and texture, when used intradermally. Recent studies suggest that combining botulinum toxin with o…

Chin augmentation and jawline contouring have emerged as significant procedures in aesthetic medicine, addressing both structural and age-related changes in the lower face. This review explores anatomic-based diagnosis and filler injection …

[BACKGROUND] There are several treatment options to improve a double chin, such as contour injections, thread lifting, and double chin liposuction. However, the results of these treatments can be minimal or have a short-lasting effect. Addi…

[BACKGROUND] Demand for noninvasive body contouring is rising as patients seek alternatives to liposuction. We evaluated a device combining electrical muscle stimulation, radiofrequency, and vacuum technology for abdominal fat reduction and…

Hyaluronic acid (HA) fillers offer a minimally invasive alternative for breast augmentation, appealing to young female patients seeking natural results and minimal recovery time. However, achieving optimal outcomes requires a thorough under…
