This study developed a hydrogel from glycol chitosan and silica nanoparticles, which showed promise in wound healing by supporting microvessel and hair follicle growth in skin defects.

This study found that an injectable ceria-based nanocomposite hydrogel improved wound healing and epithelium regeneration, including hair follicle and adipocyte tissue formation, in full-thickness skin wound models.

This review discusses complications from hyaluronic acid filler treatments and explores their causes, presentation, and possible treatment guidelines, without presenting new results.

This review discusses the potential applications of injectable platelet‐rich fibrin in various conditions and reports no new clinical results; the authors highlight its favorable use in comparison to existing treatments.

This review detailed the types and mechanisms of injectable "skin boosters" and evaluated their effectiveness and safety for mitigating age-related skin changes, providing insight into their use in contemporary dermatological practice.

In this study, an injectable hydrogel incorporating antibacterial agents was shown to effectively heal wounds and promote hair follicle and capillary regeneration, offering a promising approach for skin tissue engineering.

This study found that injectable platelet-rich fibrin (i-PRF) showed improved hair growth in males with Type VI and Type VII alopecia, which are typically difficult to treat.

The hydrogel dressings speed up healing and reduce scarring.

This study found that gelatin microspheres loaded with platelet-rich plasma enhanced wound healing in rats by improving inflammatory and angiogenic responses compared to untreated wounds or PRP alone.

In this study, iL-PRF injections produced significantly better clinical scores for androgenetic alopecia patients compared to controls, especially in those with more severe baseline conditions.

In this study, shear-thinning silk nanofiber hydrogels were found to enhance retention of mesenchymal stem cells and accelerate wound healing in rat models.

This study found that Juvéderm Ultra Plus was safe and effective for correcting severe nasolabial folds in a Chinese population, requiring less volume than Restylane while achieving similar responder rates, with fewer severe treatment site reactions.

This manuscript explores the development and future potential of injectable biomimetic gels in biomedical applications, highlighting their promise in wound healing and tissue regeneration, while also acknowledging challenges like mechanical durability and scalable production still persist.

This study synthesized a temperature-sensitive hydrogel with strong antibacterial capabilities against S. aureus and E. coli, demonstrated via in vitro and in vivo tests, suggesting potential for antibiotic-free clinical applications when activated by near-infrared light.

This study found that women with negative or mixed feelings about Botox and facial fillers reported diverse and sometimes persistent physical and psychological impacts, feeling commodified, fractured, abandoned, reflective, and transformed.

In a study using a rat model, researchers developed injectable hydrogels from antler reserve mesenchyme which enhanced regenerative healing of full-thickness cutaneous wounds by creating a fetal-like niche that increased stem cell presence and modulated gene expression related to wound healing.

In this study, injectable platelet-rich fibrin (i-PRF) was found to enhance the proliferative, migratory, and hair-inducing abilities of dermal papilla cells more effectively than platelet-rich plasma through the TGF-β/Smad pathway.

This study highlights the versatility and potential of injectable hydrogel nanocomposites in biomedical research, emphasizing their roles in controlled drug delivery, tissue regeneration, and treatment of various conditions, such as cardiac issues, joint diseases, and bone regeneration.

This study found that injectable platelet-rich fibrin (i-PRF) enhances hair follicle regeneration in vitro by promoting human dermal papilla cell proliferation, migration, and trichogenic inductivity, with varying effects depending on concentration.

This article discusses the potential of platelet rich plasma injections for treating hair loss but reports no new clinical results, emphasizing the need for further research.

AI-09 is safe, effective, and reduces wrinkles for up to 6 months.

This study evaluated the safety and effectiveness of HASHA, a new hyaluronic acid injectable, for chin augmentation in adults with chin retrusion. HASHA significantly improved chin appearance and satisfaction over 12 months compared to controls, with only mild or moderate transient adverse events.

This study found that a hydrogel made from human placenta-derived ECM, copper, and endothelial progenitor cells significantly enhanced pressure ulcer healing in a mouse model by improving wound closure and tissue regeneration.

In this study, researchers developed a biomacromolecular hydrogel to deliver plant-derived extracellular vesicles for treating androgenetic alopecia in a mouse model, which significantly improved hair regrowth and follicle density by activating Wnt/β-catenin signaling.

This study concluded that in female pattern hair loss patients, CGF and i-PRF treatments were more effective than PRP in increasing target area hair count, with i-PRF having the lowest adverse event rate.

This review provides a comprehensive look at injectable treatments like PRP, stem cells, and exosomes for hair regrowth, highlighting their potential to minimize systemic and localized side effects associated with conventional medications, and improve patient care by stimulating natural hair growth.

This study reviewed evidence on injectable regenerative treatments for female pattern hair loss, finding that while PRP consistently improves hair density and thickness, the impact of such treatments on psychological wellbeing remains unclear, and patient-reported outcomes are inconsistently assessed.

In this systematic review, researchers found that injectable therapies, including agents like dutasteride and multivitamin formulations, may offer cosmetic benefits for androgenetic alopecia; however, evidence is limited by small study sizes, varied methods, and short follow-up periods, necessitating standardized trials for routine use recommendations.
