The primary objective of this systematic review study was to investigate the effectiveness, durability, and adverse events PLLA treatment for aesthetic indications. search strategy performed in MEDLINE (Ovid). electronic literature five databases performed, from inception until 12th February 2024. This identify randomized clinical trials that assessed adult individuals exhibiting facial aging and/or lipoatrophy. Risk bias using Cochrane Risk-of-Bias Tool Randomized Trials (RoB 2). Eleven RCTs out 1467 identified citations were included. Four studies showed increased dermal thickness, significant improvement lipoatrophy severity scores, after with its effects sustained at least 25 months. Two demonstrated superiority over injectable human collagen. Also, three positive results favoring when compared PH gel severity, transepidermal water loss, skin quality, elasticity, patient satisfaction. All mild-to-moderate intensity, main ones worth noting bruising, hematoma, tenderness, nodules, edema. Five eleven considered having high risk bias. evidence on effectiveness safety rejuvenation is low quality; thus, reported safety, long-lasting purpose should be further investigated.

Poly-L-lactin acid (PLLA) has been widely used in the field of bio-medicine. In 2004, as an injectable material, PLLA was approved by FDA to treat AIDS-related facial atrophy. Since then, several stuffs containing have for marketing various countries and regions. Recently, often rejuvenation problems like cutaneous depressions static wrinkles which always induce unsatisfactory expression. This review introduces physicochemical properties, regeneration stimulating mechanism, applications aesthetics comorbidity PLLA.

Dermal fillers have gained significant attention in the field of aesthetic medicine due to their ability restore volume and correct facial wrinkles. Even though such formulations similar compositions, they can different microstructure molecular characteristics, which turn affect biodegradation profile. This study presents results an investigation physicochemical characteristics four dermal from manufacturers (Sculptra®, Gana V®, AestheFill®, Repart PLA®). The supramolecular polylactic acid (L/D isomer ratio, weight, degree crystallinity), morphology size PLA microparticles were determined. Hydrolytic degradation studies phosphate buffer revealed differences rate weight reduction polymer. obtained data may be important for analysis interpretation biological clinical outcomes fillers.

The growing interest in maintaining a youthful appearance has encouraged an accelerated development of innovative, minimally invasive aesthetic treatments for facial rejuvenation and regeneration. close correlation between tissue repair, regeneration, aging paved the way application regenerative medicine principles cosmetic dermatology. theoretical substrates applications dermo-aesthetics are plentiful. However, dermatology is emerging field needs more data vivo trials to reach consensus on standardization methods. In this review, we summarize techniques as they apply dermatology, suggesting unexplored fields future directions.

Abstract Materials of different allogeneic or xenogeneic autologous origins are widely used as soft-tissue fillers structural scaffolds in the field cosmetic surgery, while complications including prosthesis infection, donor site deformity and filler embolization have always been difficult problems for plastic surgeons. The application novel biomaterials may bring hopeful solutions these problems. Recently, some advanced biomaterials, such regenerative can effectively promote repair defective tissues, which proven to good therapeutic well effects surgery. Therefore, with active compounds drawn significant attention tissue regeneration reconstructive esthetic treatment. Some applications achieved better clinical outcomes than traditional biological materials. This review summarized recent progress

Dermal filler and botulinum toxin injections are among the most performed non-invasive procedures for rejuvenation contouring, internationally. Although dermal fillers approved toxins well tolerated with a high safety profile, adverse events and/or complications can happen. Injection-related sequelae side effects usually rare, mild, transient, self-limiting in nature. However, devastating life-changing complications, such as intravascular occlusion, skin necrosis, permanent visual impairment, stroke, have been reported. Risk reduction measures include an in-depth knowledge of anatomy, physiology, pharmacology, correct patient selection, identification clinical indications, and, fundamentally, importance appropriate skill training. In this paper, some discussed advice on how to minimise from these injectables is provided.

Recent research has indicated that in the upper face a delicate arrangement exists between muscles of facial expression and skin. This allows for immediate transmission movements following muscle contraction, resulting skin rhytid formation.To investigate age-related changes biomechanical unit formed by muscles, their connective tissue envelope, face.A total 76 Caucasian volunteers (30 males, 46 females) with mean age 42.2 years (SD 18.6) body mass index 24.58 kg/m2 3.7) were investigated. Three regions analyzed firmness elasticity cutometric assessment, vertical horizontal vector displacement using 3-dimensional imaging, activity surface-derived electromyography.Study participants older (>42.2 years), when compared younger (≤42.2 showed increased firmness, at 0.20 mm vs 0.30 (P < .001); decreased 53.2% 69.0% (not horizontal) mobility 3.56 1.35 electromyography (sEMG) signal frontalis 174 µV 309 = .039).This study reveals occur each component face.

The development of injectable hydrogels with natural biopolymers such as gelatin (Ge) and hyaluronic acid (Ha) is widely performed due to their biocompatibility biodegradability. combination both polymers crosslinked N-Ethyl-N′-(3-dimethyl aminopropyl) carbodiimide hydrochloride (EDC) can be used an innovative dermal filler that stimulates fibroblast activity increases skin elasticity tightness. Thus, Ge/Ha different concentrations EDC were administered subcutaneously test efficacy in young old rats. At higher concentrations, the viscosity decreases while particle size increases. all EDC, amino carboxyl groups are present. histological analysis shows acute inflammatory response, which disappears seven days after application. one three months post-treatment, no remains found, number fibroblasts comparison control. In addition, elastic modulus treatment. Because EDC-crosslinked biocompatible induce increased tension, proliferation, de novo extracellular matrix production, we propose use a treatment attenuate wrinkles expression lines.

A filler composed of calcium hydroxylapatite and carboxymethylcellulose gel (CaHA/CMC) has been shown to possess biostimulatory skin-tightening properties that have applied not just the face but also body boost rejuvenation. Recently, evidence recommendations for CaHA/CMC treatment provided, they are still lacking in terms treatment. This article aims perform a systematic review literature on applications provide from literature. Currently, only FDA-approved indication is treating hands recent European Union Medical Device Regulation approval released decolletage The application hyperdilutions neck, feet, arms, thighs, abdomen, other parts proven effect. However, despite their wide use with good safety profile clinical practice, trends guidelines diluted hyperdiluted yet be supported by randomized controlled trials.
