This case report describes a 28-year-old male who developed a subpericranial abscess, an unusual complication of subpericranial hematoma, potentially related to microneedling procedures, highlighting a risk of infection even without open wounds.

This literature review conducted a comprehensive analysis of existing studies on micro-needling mesotherapy in dermatology and aims to offer a practical guide for its clinical application, though it provides no new experimental findings.

This review found that microneedling can stimulate various biological pathways to promote tissue remodeling, enhance skin regeneration, and benefit conditions like wound healing and skin rejuvenation, with emerging uses in targeted drug delivery and periodontal therapy.

This study found that microneedles based on polyphosphazene with green tea polyphenols significantly enhanced wound healing in a diabetic rat model.

This study examined the effects of microneedling on dogs with non-inflammatory alopecia and found that it may aid hair regrowth, especially for those with controlled endocrine disorders but persistent alopecia, as demonstrated by hair regrowth observed over 12 months in specific cases.

This systematic review examines the landscape of cosmetic microneedling using SWOT analysis, identifying strengths like precise delivery and self-administration, while noting challenges such as potential skin damage and regulatory issues, with opportunities in AI-enhanced targeted treatments noted by these researchers.

This study found that using hair follicle units to treat hard-to-heal wounds led to complete or partial closure in most patients, with reduced operation time, minimal morbidity, and low complication rates and costs.

This study observed that repeated low-depth microneedling in patients with androgenetic alopecia led to initial hair improvement but subsequently caused hair-shaft fragility and breakage, suggesting iatrogenic damage.

This study found that pen-type microwells enhanced hair follicle germ formation by promoting cell assembly, suggesting microwell array geometry significantly influences in vitro hair follicle development.

This article discusses the premade slit method in hair restoration surgery, emphasizing the importance of a tailored depth control instrument for optimal follicle implantation, but provides no new clinical results.

This study found that in vivo, a novel microneedle system for valproic acid delivery may improve hair regrowth efficacy by upregulating hair follicle development pathways more effectively than topical application.

In this study, researchers developed a new self-administered finasteride delivery system using powder-carrying microneedles that improved hair growth efficacy and addressed safety concerns compared to topical finasteride gel by allowing sustained intradermal release of the drug for three days with a single application.

This study demonstrated that customized microneedle arrays can precisely induce targeted hair regeneration and improve hair quality in mice, potentially offering a personalized treatment approach for hair loss.

Micrografts are useful for healing wounds, regenerating bone and periodontal tissues, and improving hair transplantation outcomes.

This article discusses approaches to minimize mechanical damage during hair restoration surgery to improve micrograft viability and outcomes, but it reports no new results.

In this study, multiple mini punch grafts significantly improved epithelialization, covering more than 90% of a large ulcer in a 6-year-old boy after eight weeks.

This abstract provides no specific research findings; it appears to contain journal subscription information and other non-research content.

This study suggests that sericin microneedles with antibacterial and directional traction functionalities may enhance infected wound healing by improving skin repair and inhibiting bacterial growth, indicating potential for clinical application.

This review found that microneedling appears to be a safe and effective option for treating scars and wrinkles, with fewer side effects and shorter recovery time than some other treatments.

In this study, mathematical analysis suggested that a 30°-sapphire blade caused the least tissue injury during hair restoration, while a rectangular blade caused the most.

This review discusses the design, properties, and potential applications of smart microneedles, with no new clinical results presented.

This study observed that in mice, small-scale x-ray irradiation resulted in uniquely rapid healing of hair follicles, differing from the hypertrophic and hyperplastic responses seen in larger irradiated areas.

In animal studies, this research found that minoxidil-loaded air-pocket microneedles improved hair loss treatment efficiency compared to topical application, while effectively sealing punctured skin openings.

This review summarizes the application of microneedles in treating various skin diseases and highlights challenges like low drug loading, noting no new clinical results are reported.

This study found that dermis micrografting improved hair growth and density in patients with androgenetic alopecia over 4, 6, and 12 months, suggesting it could be a novel treatment option.

This review discusses the potential effectiveness of cell therapy for hair loss, highlighting promising early findings but emphasizing that more research is needed to explore specific therapies like autologous fat grafting and mesenchymal stem cells.

This article reviews advancements in hair transplantation, highlighting robotic and follicular unit techniques, and discusses adjuvant modalities like platelet-rich plasma, lasers, and stem cells without reporting new clinical results.

This review discusses novel treatments for androgenetic alopecia, including therapies like platelet-rich plasma and adipose-derived stem cells, and reports no new clinical results.

Combining microneedling with platelet-rich plasma enhances skin repair and collagen production but may not offer significant extra benefits.
