Marionette lines

The pathogenesis of marionette lines involves a complex interplay of anatomical, physiological, and age-related factors leading to the development of wrinkles around the oral commissures. This exploration delves into the distinct anatomical predispositions observed among different ethnicities, emphasizing the role of compact modiolus structures and muscle compositions. Notably, individuals of East Asian descent exhibit inherent facial structures that predispose them to pronounced sagging around the oral commissures during aging...

BACKGROUND: Neuromodulator treatments of the perioral region are increasingly popular and aim to modulate the position of the modiolus. The predominantly targeted muscle is the depressor anguli oris (DAO) which allows for the modiolus to reposition cranially once temporarily relaxed. OBJECTIVES: To identify the precise anatomic position of the DAO in relation to the Marionette Line for increasing precision and reducing adverse events during neuromodulator treatments...

Monopolar radiofrequency (RF) non-invasively tightens and rejuvenates the skin by stimulating collagen fiber production. Since the introduction of the monopolar RF device in the early 2000's, RF devices have advanced and they can rejuvenate of periorbital and forehead wrinkles, as well as skin laxity of the lower face and neck. We compared the differences in the treatment effects based on the tip size. This randomized split-face study comprised 31 participants aged 29 to 75 years old (three males and 28 females) who underwent one session of monopolar RF; one side of the face was treated with a 3cm2 tip and the other with a 4cm2 tip...

BACKGROUND: The Restylane portfolio of soft tissue fillers spans a wide range of indications, due in part to their complementary manufacturing technologies [non-animal stabilized hyaluronic acid (NASHA) and Optimal Balance Technology (OBT/XpresHAn)]. Using an array of products, injectors can achieve a holistic, natural looking effect for their patients. However, with a wide range of products it may be difficult to choose an optimal combination. AIM: Simplify and align global use recommendations for NASHA versus OBT products...

Perioral tissues are among the first areas to show signs of facial aging, leading many patients to seek perioral fillers as their initial cosmetic treatment. These fillers offer a temporary solution by enhancing volume and reducing common facial lines. Various regions within the perioral area can be targeted, including the lips, nasolabial folds, philtral columns, vertical lip rhytids, oral commissures, melomental folds, mentolabial folds, and nasolabial folds. The technique for injecting perioral fillers depends on the specific region, chosen product, and the desired outcome of augmentation...

BACKGROUND: A validated scale is needed for objective and reproducible comparisons of marionette lines before and after treatment in clinical studies. OBJECTIVE: To describe the development and validation of a 5-point photonumeric marionette lines scale. METHODS: The scale was developed to include an assessment guide, verbal descriptors, and real and morphed subject images for each scale grade. Intrarater and interrater reliability was evaluated in initial scale validation (web-based review) (N = 51) and live-subject validation (N = 75) studies, each completed during 2 sessions...

Radiesse® is a filler composed of calcium hydroxylapatite microspheres suspended in a carboxymethylcellulose gel (CaHA/CMC). It has robust rheological properties that have been associated with its versatility. CaHA/CMC is employed for both on-label indications of filling wrinkles or lines, volumizing, and contouring of areas as well as off-label indications aiming at biostimulation and skin tightening. However, despite the expanding use of CaHA/CMC, overall evidence and recommendations for treatment are currently lacking...

BACKGROUND: The nasolabial folds are the most marked sign of aging. Endolift laser was used for the treatment of nasolabial folds and marionette lines (one of the facial danger zones). METHODS: Ten female subjects were engaged in this study. Patients underwent Endolift laser for nasolabial folds and marionette lines treatment. The efficacy of the Endolift technique on the nasolabial folds and marionette lines was evaluated by biometric assessment with Cutometer, Visioface, and the Skin Ultrasound Imaging system...

PURPOSE: Injectable hyaluronic acid-based fillers are commonly used for the correction of skin contour irregularities and to smooth skin depressions formed by volume loss during the aging process. These fillers are particularly efficient to restore perioral skin depressions/wrinkles or to correct topographical anomalies. The European directives require a continuous evaluation of the performance of these medical devices, particularly for CE marked products. METHODS: An 18-month prospective randomized single-blind study for the efficacy and safety of ART FILLER Universal (AFU) was performed on the lips, the nasolabial folds, and the marionettes lines...

BACKGROUND: Facial aging is associated with the loss of soft tissue fullness. Perioral signs of facial aging can add years to individuals' appearances and even affect their facial expressions in smiling and nonsmiling images. AIMS: To evaluate the influence of the nasolabial fold on the visual perception of esthetics and age in the elderly, eye-tracking and a visual analog scale were used. MATERIAL AND METHODS: This study applied a cross-sectional study using 40 laypeople...

BACKGROUND: Data reflecting the impact of photoprotection on cutaneous aging are scarce and mostly limited to fair skin. OBJECTIVE: To assess the effectiveness of a photoprotective product in counteracting the photoaging process in different skin phototypes over 1 year compared against a classical routine. MATERIALS AND METHODS: Two hundred and ninety Brazilian women aged 30-65 years, with skin phototype II-VI were equally randomized in two groups...

BACKGROUND: Biorevitalization solutions contain numerous nutritive compounds to improve skin quality. Dermal fillers like HA (hyaluronic acid), depending on rheological characteristics, are used to fill large static defaults with a sustained long-term efficacy. Treatments with either dermal filler or biorevitalization solutions alone are not enough to bring a global facial aging approach. OBJECTIVE: To demonstrate the anti-aging performance and safety of a new protocol, BIONUTRILIFT, which combined an HA-based filler with Tri-Hyal technology and a skin biorevitalizer, to target the skin quality and wrinkles correction at the same time...

With increasing age and edentulism, numerous aesthetic changes occur to the perioral region. The upper lips lose definition, flatten and lengthen, the cupid's bow is lost, and the oral commissures descend. The nasolabial folds deepen, marionette lines become prominent, vertical rhytids around the lips form, and chin rhytids form. Chronic exposure to UVA radiation from the sun can lead to photodamage, characterized by wrinkles, lentigines, actinic keratoses, and other pigment changes. In addition, edentulism leads to jaw atrophy, which often compromises soft tissue support...

BACKGROUND: High-intensity parallel beam ultrasound (US) is a novel device equipped with Synchronous Ultrasound Parallel Beam (SUPERB) technology applied in anti-aging treatment.
