This study reported that novel adipose slurry injections improved rhytides and dermis density in patients receiving facial wrinkle treatments based on evaluations at multiple follow-up intervals.

People with acne have more CD4+ immune cells in their skin than healthy people.

This study found that adult mouse dermis can be reprogrammed by epidermal cues to resemble neonatal dermis, with changes in fibroblast proliferation and extracellular matrix composition.

In this study, researchers observed that telogen hair was more prevalent than anagen hair in both male and female agoutis over a one-year period in Teresina-PI, regardless of dry or rainy seasons, with no significant differences in dermal follicular volume between the sexes.

This study found that radiofrequency treatment, with or without hydrolyzed collagen, increased dermis thickness, neocollagenesis, and FGF2 overexpression in rat skin tissue.

This study observed that primary hair follicles in Liaoning Cashmere goats had broader hair bulb widths compared to secondary follicles, with the difference diminishing during the anagen phase of hair follicle development.

This study observed that in long-haired cat breeds, there is an inverse relationship between epidermis thickness and hair cover thickness, regardless of breed.

This study found that drug delivery through human scalp skin may be more effective for lipophilic and hydrophilic drugs compared to abdominal skin, highlighting the potential of intrafollicular delivery methods.

This study found that proper levels of retinoic acid, controlled by the enzyme Cyp26b1, are essential for normal hair follicle development and morphogenesis in mice.

This article reviews the functions and locations of skin stem cells and their role in regeneration and differentiation, relating age-associated skin changes to decreased stem cell functionality; it reports no new experimental findings.

In this study, reflectance confocal microscopy was used to diagnose periorificial dermatitis, revealing specific skin changes such as hair follicle dilatation, increased vascular density, and inflammation, which help distinguish it from similar conditions.

A new hair transplant method showed promising results and a study found how deep a CO₂ laser can penetrate skin.

This study suggests that a 1,550-nm fractional erbium-glass laser may stimulate hair growth in both an alopecia mouse model and human subjects with male pattern hair loss, though further research is needed to determine its clinical applications.

This study used multi-scale hybrid models to explore how signaling factors affect skin wound healing and embryo development, suggesting that different levels of fibrin clot density influence scar formation.

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.

In this study, neonatal mouse mesenchymal cells showed hair-inducing capabilities, which were lost during in vitro propagation but could be partially restored through specific high-density culture methods.

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 study found that elastic fibre arrangements in the skin of domesticated mammals vary with hair density, with densely-haired species having horizontal fibres and sparsely-haired ones exhibiting a sponge-like system.

This study found that DPG promoted wound healing in rat skin, with increased collagen I density, particularly evident within the first 14 days after injury.

This study found that topical mesenchymal stem cell conditioned medium improved skin structure by increasing collagen fiber density, hair follicles, and blood vessel number in a mouse model of skin aging.

This study found that single high-dose irradiation in mice induced more severe acute skin injury and hair depigmentation, while fractional doses led to longer-term damage in the dermis and subcutis.

This study observed that red sindhi cattle have variations in skin structure between age and sex groups, with more developed skin appendages in adults and a higher density of sweat glands in younger cattle.

This article reviews differences in hair characteristics between Asians and Caucasians, highlighting Asian hair's lower density and thicker dermis, and reports no new research findings.

This paper suggests that using semiconical blades and coronal slits in hair transplantation may reduce vascular damage compared to other techniques, potentially offering optimal slit creation.

This study found that dermis micrografting improved hair growth and density in individuals with androgenetic alopecia, suggesting it may be a novel therapeutic option.

In this study, researchers developed a probiotic-based microneedle system combining Weissella cibaria and clascoterone to target androgenetic alopecia, which in a mouse model improved hair density, vascular regeneration, and reduced inflammation, suggesting a promising treatment approach.

This article explores the use of monoclonal antibodies to study the presence and distribution patterns of melanocytes in developing human skin, but reports no new clinical results.

This study found that scalp involvement in dermatomyositis consistently shows a nonscarring pattern with chronic telogen effluvium, featuring telangiectasia and mucin deposition as universal histologic markers.

This study found that island grafting in guinea pigs enabled the isolated study of early skin regeneration processes, distinguishing them from natural wound closure mechanisms like epithelialization and contraction.

This study introduces a non-invasive photoacoustic imaging technique that accurately measures hair follicle density and subdermal angles, showing strong correlation with the gold-standard photographic method.
