The editorial introduces various topics on laser and cosmetic treatments in a medical journal.

In this first reported case, a 42-year-old female with Parry Romberg Syndrome was treated using hyaluronic acid filler, which the authors suggest may serve as a safe, simple, and cost-effective alternative to more complex surgical methods.

This article describes a new surgical technique called "hair-lifting" for treating male-pattern alopecia, which involves removing sections of bald scalp and repositioning remaining hair.

This source reports that the JOLT technique using HA fillers is effective in lifting and tightening the lower face and neck, camouflaging the jowl, and improving marionette lines and the mandibular border.

This study introduced a rapid rehydration approach for creating customizable, multifunctional hydrogel sensors, enabling precise detection of surface deformations and easy integration of layers, highlighting its potential for standardized and adaptable manufacturing of wearable devices.

This study highlights the significant risk of vascular embolism associated with hyaluronic acid filler injections, emphasizing concerns about potential irreversible damage when fillers are injected in "unexplored" facial areas due to complex and variable facial anatomy.

This study developed granular hydrogels with reversible interparticle cross-linking, finding they offer high mechanical stability and enhance cell recruitment, making them promising for injectable and 3D printable scaffolds in tissue engineering and therapeutic delivery.

This article discusses the delta lift procedure, which reportedly achieves a more youthful look with fewer complications than conventional face lifts by using limited skin excision and tightening techniques.

This study developed a directional pressure-pump hydrogel delivery platform that enhances wound healing in diabetic mechanically dynamic wounds by targeting antibacterial agents and nanozymes directly to the lesion site, disrupting biofilms, mitigating tissue damage, and supporting proper skin closure and vascular remodeling in animal models.

This article discusses extensive scalp lifting for male-pattern alopecia and emphasizes the need for precise surgical techniques and understanding to minimize complications, but reports no new clinical results.

This study examined a case of vascular complication following the use of hyaluronic acid-based fillers in lateral temporal lifting, resulting in livedo reticularis, alopecia, and painful injection area requiring three months of treatment.

This study found that thermoresponsive hydrogels can maintain mechanical memory in fibroblasts, enhancing wound healing compared to traditional trypsinized methods.

This review categorizes contractile hydrogels by their contraction mechanisms and explores their role in advanced wound management, emphasizing mechanical and biochemical signaling in healing, but also notes challenges like force transmission and clinical applicability.

This study introduces a magnet-assisted fabrication strategy for creating complex 3D soft bioscaffolds, demonstrating its effectiveness by producing structures with overhangs and supporting biohybrid actuators, promising advancements in biomedical applications.

This study demonstrated that a mechanical-assisted post-bioprinting strategy significantly increased cell numbers and enhanced regenerative capabilities in hollow hydrogel-based scaffolds for bone defect repair in vivo.

In this study, researchers developed a method using stencils to create controlled stiffness gradients in alginate hydrogels, revealing that stiffer regions within the gels promote deeper invasion by breast cancer cells, facilitating the study of mechanosensitive cellular behaviors.

In this study, pneumatic injections of non-cross-linked hyaluronic acid were associated with improvements in skin texture, pores, wrinkles, and transepidermal water loss in healthy female volunteers.

This study demonstrated that PEGDA hydrogel microwells successfully supported cell survival and proliferation while mimicking hair follicle architecture in vitro, suggesting a potential tool for hair follicle engineering.

In this study, researchers introduced an ultrasound-guided technique for injecting hyaluronic acid fillers into the temple area to enhance safety and precision by visualizing filler placement in the interfascial space.

This study suggests that combining LMWHA solution and HCO might improve mild to moderate urinary incontinence in women with GSM, potentially offering benefits over HA therapy alone, but further research is needed.

This study developed a prototype pneumatic dual-cell implanter that successfully stacked and implanted cells in tests, reducing hand burden for operators, which may improve alopecia treatments compared to traditional hair transplantation.

In this study, HYDRO DELUXE BIO was reported to show promise for scalp mesotherapy by enhancing angiogenesis and reducing inflammation in an in vitro model.

Pulsed dye laser and hydrogel dressings effectively treat hypertrophic scars.

This study observed that six sessions of injections using a stabilized hyaluronic acid compound improved hair thickness, shine, density, and reduced hair loss in volunteers with moderate androgenetic alopecia, with excellent treatment tolerability and high satisfaction reported by 88.5% of participants.

In this report, researchers observed that a single treatment using a combination of hyperdiluted calcium hydroxylapatite, platelet-rich plasma, and hyaluronidase improved neck wrinkles and skin laxity in two patients, indicating preliminary evidence for the safety and efficacy of this novel therapy.

In this study, an endoscopic midface lifting technique showed notable improvement in midface ptosis and infraorbital hollowing, with lower morbidity and few complications after over 400 procedures.

This review examines advancements in hydrogel formulations aimed at preventing dermal fibrosis and promoting scarless wound healing, highlighting their role in regulating myofibroblast differentiation and controlling the wound microenvironment.

In this study, dynamic hyaluronic acid hydrogels with properties like injectability and controlled degradation were developed to enhance healing and remodeling of diabetic wounds, achieving effects such as inflammation reduction, increased angiogenesis, and neovascularization, leading to complete wound healing.
