This study compared the effectiveness of different thread types in improving collagen profiles in UVB-exposed aging model rats, finding that PCL threads were more effective than PDO and PLLA in enhancing dermal collagen characteristics.

This study found that nanofibrous membranes containing PNA nanogels enhanced wound healing in mice by modulating reactive oxygen species levels, improving cell adhesion and proliferation.

This research found that hyaluronic acid increased cell proliferation and type I collagen more effectively than poly-L-lactic acid in both human fibroblast cultures and rat dermis.

This review discusses strategies for achieving natural results in male facial aging treatments using dermal and subcutaneous fillers, but reports no new clinical outcomes.

PLLA injections can cause hair loss and skin issues.

This network meta-analysis found that for female pattern hair loss, microneedling combined with minoxidil ranked highest for hair density and patient satisfaction, while poly-L-lactic acid threads plus minoxidil led in hair diameter; however, the evidence is uncertain and lacks placebo-controlled trials.

This narrative review examines advancements in regenerative aesthetic medicine, focusing on injectable modalities like PRP, polynucleotides, and exosomes, but highlights the need for more robust evidence and standardization in clinical applications.

This review highlights that injectable biostimulatory agents like poly-L-lactic acid, polycaprolactone, and calcium hydroxyapatite are effective in regenerative aesthetics by enhancing collagen production, stimulating adipogenesis, and improving dermal quality, although further research is needed to standardize protocols and confirm long-term safety and efficacy.

In this study, researchers noted that while Poly-L-lactic acid dermal fillers boost collagen synthesis to add volume and reduce wrinkles, there is no established link between these fillers and hair loss according to existing literature.

In this study, PDO, PLLA, and PCL thread implants in ageing rat skin did not alter MMP1 gene expression but maintained collagen levels similar to young skin without UV-B exposure, suggesting possible benefits for skin collagen but not gene expression modification.

This case study reports that a 35-year-old woman developed nonscarring alopecia following the cosmetic use of poly-L-lactic acid on her face and hairline.

This systematic review found that both hormonal and non-hormonal therapies for female pattern hair loss can improve hair growth, although they have different efficacy and safety profiles, with hormonal treatments like spironolactone showing higher rates of adverse effects such as menstrual irregularities.

This study reviewed evidence suggesting that the loss of dermal white adipose tissue (dWAT) during menopause may be linked to decreased estrogen levels, potentially affecting skin health, and discussed non-hormonal treatments, like magnolol, that might help restore dWAT and improve menopausal skin changes.

This article reviews the latest data on non-invasive body rejuvenation techniques, discussing advancements in filler technology and offering insights into their effectiveness and safety for both practitioners and patients interested in non-surgical procedures.

Certain combination therapies, like microneedling with minoxidil, are more effective for female-pattern hair loss than other treatments.

This study found that combining poly-l-lactic acid microthread therapy with minoxidil improved hair density and appearance more effectively than minoxidil alone in women with androgenetic alopecia.

This study reported that 4D-printed, aliphatic polycarbonate-based scaffolds supported adipose tissue engineering by allowing adipocyte infiltration and neovascularization in vivo, indicating potential for effective adipose tissue repair.

Combination therapy improves urinary flow and reduces residual urine, but needs better stent design.

This minireview discusses the mechanisms of facial aging, examines current literature, and proposes filler injection protocols, but it reports no new clinical results.

This chapter discusses the composition, biocompatibility, and production methods of biomaterials like collagen, chitin, and silk for dermal substitutes, focusing on preclinical and clinical research, but reports no new clinical results.

This review article discusses the aesthetic impacts of GLP-1 medications like Ozempic (semaglutide), including "Ozempic Face," skin sagging, and loss of lean mass, and explores potential recovery methods such as biostimulators, HIFU, endolaser, and PRP.

This review discusses recent advances in surface modification and endothelialization of biomaterials for vascular grafts, highlighting promising methods like gene engineering and targeting ligand immobilization to improve clinical outcomes.

This review examines recent advancements in electrospun nanofibers for wound healing applications, but reports no new experimental results, highlighting their potential in sutures, dressings, and skin regeneration.

This study found that chitosan nanofibrillar scaffolds accelerated skin wound healing in mice by enhancing cell adhesion, proliferation, and regeneration of epidermis and dermis compared to other forms.

This review provides an overview of recent tissue engineering and regenerative medicine developments in Asia, highlighting significant advances, representative research achievements, and discussing future directions, without presenting new research results.

This review highlights the challenges in identifying histological features of adverse reactions to soft tissue fillers and emphasizes the need for increased awareness due to product uncertainty and delayed reactions.
