This study presents a new model for the progression of androgenetic alopecia, suggesting that the loss of attachment between the bulge's stem cells and the arrector pili muscle may contribute to irreversible hair miniaturization.

In this study, researchers developed a three-dimensional ultrastructural analysis tool using serial block-face scanning electron microscopy to reveal detailed nerve networks and muscle structures in human skin tissues, demonstrating the technique's potential to study structural changes in aging or disease.

This article reviews the use of the transtemporal approach for midface and lower eyelid-cheek junction rejuvenation, detailing surgical techniques, post-operative care, and potential complications, but reports no new clinical results.

This study found that six-month supplementation with fish-derived collagen peptides, calcium, and vitamin D3 improved skin hydration and elasticity and reduced hair loss in menopausal women, with collagen playing a dominant role in enhancing skin elasticity.

This study observed that among elderly patients, the most common systemic disease associated with skin conditions was diabetes, while wrinkling and xerosis were prevalent skin changes.

In this study, procerus and corrugator myectomy techniques during browlifts significantly improved dynamic glabellar wrinkles compared to browlifts without muscle resection over 12 months.

This review highlights research reporting that oral collagen peptide supplements are effective in enhancing skin elasticity, hydration, and reducing wrinkles, although results vary across studies. Oral supplementation was generally well-tolerated, and further investigation is needed to optimize formulations and explore topical application challenges.

This article discusses the philosophy and strategies for dense packing in hair transplantation, emphasizing that not all patients are candidates, and reports no clinical results.

This article describes techniques for hair restoration surgery, including using intradermal sutures for donor area closure and employing the retroauricular ellipse from a facelift as a donor site, but reports no new clinical results.

This review covers complications of neck lift surgery, their causes, ways to reduce them, and management strategies, without offering new clinical findings.

This review discusses the potential of adipose-derived tissue components like nanofat and stem cells for aesthetic rejuvenation, covering their use in hair growth, scar reduction, and more, without reporting new clinical results.

This study found that TGFbeta is a key pathway causing age-related loss of dermal fat's antimicrobial function, suggesting that targeting TGFBR might help restore skin defense against infections in older age.

This review reports that collagen peptides consistently provide modest improvements in skin hydration and elasticity and varying benefits for body composition and cardiometabolic markers, although effects on blood sugar control are less consistent; variations in source, dose, and study definitions limit generalizability.

This study observed that mink dermal collagen fibrils undergo structural changes during the hair cycle, with increased fiber thickness and bundle density as minks grow.

Older adults may experience painful finger pitting due to nerve changes in aging skin, and treatments can help reduce symptoms.

This study found that residual sweat glands in hypertrophic scar tissues may regenerate from adult epidermal stem cells or residual glands after burn injury.

This study found that arthritis and mucocutaneous features are common at early stages of SLE, while sicca, vasculitis, and hematologic manifestations tend to increase as the disease progresses.

This study found that young adult Ukrainian men with alopecia areata had significantly different skinfold thickness at several body sites compared to healthy peers, suggesting unique patterns of fat distribution associated with the disease.

This review identifies excessive sebum, decreased elasticity, and increased hair follicle volume as key factors contributing to enlarged skin pores, emphasizing the need for individualized treatment based on underlying causes.

This study observed that both Factor XIIIa+ dermal dendrocytes and microvasculature size decreased with scalp aging and that alopecia changes resembled stress-induced premature senescence.

The man has a disease causing skin patches, thickened nerves, and mild muscle weakness.

This report documents a rare case of familial eyelash trichomegaly and synophrys in three siblings, with one sister also having loose anagen hair syndrome, an unreported association.

Mesenchymal stiffness affects sweat gland cell development.

This article presents a case of a 45-year-old African American man with firm, hyperpigmented papules and pustules on his cheeks and neck, persisting despite various shaving methods.

This report describes a rare case of sarcoidosis occurring on an old blepharoplasty scar in a leukemia patient, suggesting the need for a skin biopsy when firm papules appear on a scar.

This article reviews methods for temple region rejuvenation and reports no new clinical results; the authors emphasize the importance of understanding temple anatomy for optimal aesthetic outcomes.

This study found that genomic instability in mouse models impair hair follicle regeneration, suggesting potential parallels in age-related hair loss in humans.

This review discusses the anatomy, aging pathophysiology, and various surgical and non-surgical options for rejuvenating the upper face, including antioxidants and non-ablation laser, but reports no new clinical results.

The study found that a single autologous micrografting treatment using Rigenera® technology significantly improved the appearance of stretch marks in healthy women after three months, showing greater enhancements in skin properties compared to microneedling alone.

This study found that minimally invasive combined fascia sheath suspension improved eyelid symmetry in patients with unilateral ptosis, particularly in measures of marginal reflex distance and eyelid contour.
