This study found that, in Japanese patients with androgenic alopecia, sebaceous glands exhibit increased multilobulation which may be significant in the condition's pathology.

The modified S pattern for scalp reduction is effective for removing more bald scalp and hiding scars in hair restoration.

This study found that neck defect size was more relevant than total body surface area for predicting contracture recurrence after burn injury, suggesting increased attention to defect size in managing such cases.

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 in Japanese, German, and American females, changes in hair lipid patterns with age may reflect alterations in sebum excretion and affect hair texture.

This study found a significant relationship between lash ptosis severity and marginal reflex distance, levator function, and double fold presence in Asian patients, which may inform surgical planning for upper eyelid procedures.

This study discovered that adipose tissue infiltration at the isthmus level appears significantly more often in frontal fibrosing alopecia cases compared to controls, suggesting a potential role in the condition's pathology.

This study reports that aging in human skin involves early photo- and inflammation-related cellular changes, and suggests restoring KLF6 and HES1 expression might reverse some of these age-associated changes.

This systematic review found that exosome-based therapies significantly improve skin elasticity, reduce wrinkle depth, enhance hydration, and modulate pigmentation, with minimal adverse events reported across multiple studies. However, further clinical trials are necessary to confirm long-term efficacy and safety.

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.

The book provides practical guidance on cosmetic facial surgery for clinicians.

This study found that topical niacinamide significantly improved the appearance of wrinkles, skin yellowing, and elasticity in aging facial skin over 12 weeks.

This chapter discusses current nonsurgical facial rejuvenation techniques such as skin treatments and injectable fillers, but it reports no new clinical results.

This case report describes a 23-year-old man with scurvy, characterized by perifollicular hemorrhages, gum disease, and other symptoms due to a diet low in fresh fruits and vegetables.

This study found that immune-mediated destruction of bulge stem cells is a key factor in the alopecia observed in AE mice, suggesting it as a model for studying primary cicatricial alopecias, particularly lichen planopilaris.

This study found that decreased COL17α1 expression in aging mouse skin is associated with reduced proliferation of epidermal stem cells and may contribute to thinner epidermis and slower wound healing.

Cosmetic procedures can improve skin appearance and boost confidence.

This study reports that the asebia-2J mutation in mice affects sebaceous gland function and leads to hair follicle destruction, offering a model for human scarring alopecias.

Loose anagen hair syndrome in children may improve with age, but treatment results vary.

In this study, researchers investigated changes in ribosomal RNA modifications associated with stress-induced cellular senescence in human skin cells, identifying potential biomarkers and targets for interventions to mitigate skin aging.

This study demonstrated that CD19-CAR T cell therapy may promote structural regeneration in the skin of systemic sclerosis patients, as evidenced by histological improvements and fibroblast population changes, suggesting its potential for tissue remodeling in fibrotic diseases.

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.

Older East and Southeast Asian men need less hair density for hair restoration satisfaction, and natural hairline features should guide surgery plans.

In this study, patient-reported outcomes indicated that greater weight loss with GLP-1RA treatments was associated with increased reports of adverse cosmetic effects such as skin laxity, facial volume loss, and hair shedding, despite improvements in some preexisting inflammatory skin conditions.

This study found that age-related hair thinning in Caucasian women over 50 involves significant structural changes within the hair follicle, suggesting an "aged hair program" rather than just producing thinner hairs.

This study suggests that age-related regenerative decline in hair follicles may be due to an imbalance of signals affecting stem cell activation, with follistatin potentially promoting renewal.

This study found that perceptions of scalp micropigmentation and awareness of its side effects vary significantly by gender and age, influencing attitudes and intentions toward the procedure.

This review discusses the potential esthetic applications and regenerative properties of adipose-derived stem cells but reports no new clinical findings, emphasizing the need for further research to establish efficacy.

This study found that sphynx cats exhibit hair follicle dysplasia with abnormal hair shaft production, but without a reduction in the number of follicles, similar to murine KRT 71 mutants.

This study found that fractional ultrapulse CO2 laser resurfacing effectively enhanced upper eyelid crease and brow position in patients with low and moderate dermatochalasis, with only mild side effects reported.
