This article discusses the distribution of extracellular matrix molecules in human hair follicles and reports no new results.

This study found that GAGS scores for acne were higher in younger women with PCOS and a lower BMI, but showed no association with levels of androgen hormones.

This study demonstrates the potential of infrared spectral imaging to assess hair follicle structures and heparan sulfate proteoglycan distribution across different phases of the hair growth cycle, offering promise for alopecia research.

This study found that glycosaminoglycan levels were higher in the occipital area of the hair shaft compared to the parietal area, with children showing higher levels than adults.

This study observed that rat dermal tissue cultures, rich in hair follicle cells, produce various glycosaminoglycans, including hyaluronic acid and dermatan sulfate, which change in synthesis and sulfation patterns over time.

This study found that applying glycosaminoglycans fractions from ascidian tunics stimulated human follicle dermal papilla cell proliferation and, when used on mice hair for 28 days, produced a hair growth effect comparable to Minoxidil.

This review discusses the roles and mechanisms of glycosaminoglycans in wound healing and presents challenges and potential applications for GAG-based biomaterials without reporting new experimental results.

The researchers reported that marine-derived saccharides, specifically L-fucose and chondroitin sulphate disaccharide, supported skin and hair health by promoting cellular proliferation, enhancing extracellular matrix production, and aiding the hair cycle's growth phase, potentially minimizing aging effects.

Skin aging reflects overall body aging and can indicate internal health conditions.

In this study on wound healing, sulfated glycosaminoglycans from sturgeon cartilage enhanced fibroblast cell proliferation, migration, and collagen deposition, significantly accelerating wound closure and promoting re-epithelialization in both in vitro and in vivo tests.

This study observed that using an environmentally friendly bovine milk permeate effectively and cleanly removes wool from sheepskins without harming the skin, and results in smoother leather compared to traditional chemical methods.

This study suggests that glycosaminoglycans, like hyaluronic acid obtained biotechnologically, are safe for topical cosmetic use, enhancing skin and hair conditions by supporting cell renewal, stimulating hair growth, and aiding in the treatment of scalp issues such as seborrhea and androgenetic alopecia.

This study suggests that activating the hexosamine pathway may enhance skin homeostasis, potentially increasing hair follicle stem cells and modifying extracellular matrix components like hyaluronic acid in vitro.

Some nutrients and antioxidants may improve skin and hair health, but more research is needed to confirm these benefits.

This study observed that hereditary factors were associated with acne duration but not severity, and found a potential role of CYP450 1A1 polymorphisms in acne pathogenesis.

In this study, researchers investigated GAGs from the marine invertebrate Microcosmus exasperatus, finding that its polysaccharides possess antitumoral properties without affecting anticoagulant activity. The unique composition shows potential for cancer treatment when combined with existing therapies in future studies.

This review explores the eggshell matrix as a potential sustainable and cost-effective alternative source for glycosaminoglycans, but highlights the need for further research to enhance extraction techniques and economic viability.

This study observed that a significant proportion of women with acne vulgaris also met the criteria for PCOS, suggesting a notable link between the two conditions.

This review discusses the diverse clinical manifestations of mucopolysaccharidoses in children and emphasizes the importance of early diagnosis and treatment initiation, but it reports no new clinical findings.

In this case-control study, researchers found that serum apelin-12 levels were significantly higher in acne patients and correlated with acne severity, BMI, insulin resistance, and inflammation, suggesting that managing insulin resistance could be important for acne treatment.

New materials and methods could improve skin healing and reduce scarring.

This study concludes that fetal skin cells can significantly enhance wound healing and reduce scarring when used to treat severe burns and various wounds in children.

This review discusses the effects of oestrogen on skin ageing and highlights the need for large-scale clinical trials to evaluate postmenopausal oestrogen use, reporting no new findings.

This study reports that the tetrapeptide AcSDKP significantly promotes skin and hair health in vitro and ex vivo, suggesting it could be used cosmetically to counteract skin aging and hair loss.

This report describes a case of primary cutaneous follicle centre cell lymphoma presenting as hair thinning on the scalp, which is not a recognized feature of the condition.

In this study, gender-affirming hormonal treatment was associated with increased hair growth, acne, and alopecia prevalence in transgender individuals assigned female at birth, while opposite dermatological changes were observed in those assigned male at birth.

This study suggests that the gene rs27647 polymorphism may play a role in the pathogenesis of severe acne vulgaris in post-adolescent male patients.

In this study, growing human hair follicles in a defined glycosaminoglycan hydrogel ex vivo promoted cell survival, proliferation, and activation of hair growth-related signaling pathways, suggesting GAG-based hydrogels could modulate the hair follicle growth cycle.

Minoxidil boosts hair growth by undergoing a process in hair follicles and certain skin cells, and by increasing the production of compounds essential for hair growth and maintenance.

In this study, combining microneedle and sublative fractional radiofrequency treatments significantly improved skin tightening, texture, collagen organization, and satisfaction in individuals with moderate photoaging, while reducing abnormal elastin after three months.
