[BACKGROUND] Dermal filler injection can restore facial volume and improve contour; however, the precise mechanism underlying its lifting effect remains insufficiently characterized. This study explores how targeted filler placement within …

Understanding the anatomic relationship between facial surface lines and underlying vascular networks is critical for safe dermal filler augmentation. This review presents a systematic taxonomy classifying facial surface changes into 5 cate…

[BACKGROUND] Nasolabial folds (NLFs) are a hallmark of facial ageing, and precise correction requires detailed anatomical and vascular mapping. High-resolution ultrasound offers real-time visualisation of soft-tissue layers, filler distribu…

[BACKGROUND] The platysma muscle plays a pivotal role in the formation of vertical neck bands and contributes to lower facial descent, making it a prime target for botulinum toxin type A (BoNT-A) in aesthetic neck rejuvenation. Conventional…

[BACKGROUND] Hyaluronic acid (HA) fillers are commonly used in esthetic medicine for facial contouring and rejuvenation. However, complications such as overcorrection, vascular occlusion, and irregular filler distribution necessitate the us…

This narrative review explores the various injection techniques utilized in facial filler procedures, emphasizing their applications, benefits, and potential complications. The increasing demand for total facial contouring and rejuvenation …

Lip augmentation has become increasingly popular in aesthetic medicine, driven by advancements in dermal filler technologies and injection techniques. This review provides a comprehensive overview of lip anatomy, age-related changes, and cu…

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…

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…

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 …

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 …

Supraorbital hollowness and pretarsal fullness, commonly known as the sunken eyelid and charming roll, respectively, are significant anatomical features that impact the aesthetic appearance of the periorbital region. Supraorbital hollowness…

[BACKGROUND] Nonsurgical rhinoplasty (NSR) with dermal fillers has gained popularity because of its immediate and visible results, minimal downtime, and long-lasting effects. However, complications such as filler migration can lead to the d…

Nasal augmentation using dermal fillers has become a popular nonsurgical esthetic procedure, particularly among Asian populations. This review explores the anatomical considerations, injection techniques, and safety measures essential for s…

Vascular complications arising from dermal filler treatments pose significant risks, including ischemia, tissue necrosis, and severe outcomes like blindness and pulmonary embolism. This study investigates the mechanisms of vascular complica…

The increase in the use of filler treatments within minimally invasive cosmetic surgery has correspondingly escalated the variety and frequency of associated side effects. Initially, unregulated procedures led to primary side effects such a…

Hyaluronic acid (HA) fillers are extensively utilized in aesthetic medicine due to their biocompatibility, reversibility, and effectiveness in enhancing skin hydration, volume, and overall appearance. These fillers are predominantly produce…

[INTRODUCTION] Non-surgical rhinoplasty has evolved with the introduction of volumizing threads, which offer a less invasive alternative to traditional methods by enhancing nasal contours while minimizing filler use. This technique is gaini…

[BACKGROUND] The cross-linked hyaluronic acid (HA) fillers are the viscoelastic hydrogel with a dominant elasticity rather than a viscosity as a useful medical device in the soft tissue augmentation. These HA fillers undergo deformation to …
