This study identified distinct differences between mature and immature hypertrophic scars of the head and neck, with immature scars showing higher TGF-β expression and more pronounced inflammatory reactions.

This study found that TGF-β2 may enhance collagen expression and spheroid formation in human dermal papilla cells, which could improve their hair inductivity and maintenance.

This review suggests that although hydrolyzed collagen peptides with certain supplements may improve skin elasticity and joint function, evidence for collagen's anti-aging and regenerative benefits remains inconsistent.

This study discusses how redox imbalance, specifically through reduced Insulin-like Growth Factor-1 mediated by the transcription factor JunB and sphingolipid metabolism changes, contributes to skin aging by depleting stem cell pools and altering the extracellular matrix, ultimately impacting skin integrity and function.

This study found that dermal sheath stem cell characteristics are lost with aging in humans, affecting skin rejuvenation and structure, and identified specific proteins like Activin A influencing keratinocyte and fibroblast activity.

This review discusses the significance of elastic tissue staining in dermatopathology, particularly for diagnosing primary elastic tissue disorders and other skin conditions, but reports no new clinical results.

In this study, researchers found that glycan profiles in epidermal stem cells differed between young and old mice, suggesting these changes may serve as molecular markers for aging.

A new method was developed to create better skin models for healing and reconstruction.

This study found that selective downregulation of CD200 in the bulge area might contribute to unusual bulge involvement in a subset of alopecia areata cases.

This review discusses the impact of menopause-related oestrogen deficiency on skin ageing and suggests that oestrogen use may improve collagen and skin elasticity, but it reports no clinical trial results.

This study examined the subcutaneous structures in forehead creases using cadavers and observed that dense fibrous structures connecting the dermis to the frontalis muscle, as well as specific epidermal and dermal characteristics, may contribute to the formation of these creases.

This study found that rabbit skin histology revealed changes in collagen and elastic fibers after soaking, dehairing, and tanning processes, impacting fiber tightness and fur removal.

The study found that applying Bifidobacterium-fermented soy milk extract to human skin significantly reduced the decline in skin elasticity, suggesting its potential as a cosmetic ingredient to prevent skin aging.

In this study, researchers found that patients with non-scar alopecia exhibited thinner hair sacs and root sheaths compared to a control group, with significant thinning observed in cases of alopecia areata.

This case report concludes that the presence of distinctive histiocytic responses in a Cambodian woman's eyelid lipogranulomas suggests surreptitious silicone injections despite her denial of prior procedures.

This article discusses advancements in managing the aging brow and forehead, reporting on a tailored problem-specific approach using both innovative technologies and traditional surgeries, but provides no new clinical results.

This study observed that fibrosis occurs in the bulge region of hair follicles affected by androgenetic alopecia and is correlated with the hair miniaturization process.

This report describes a case of scarring alopecia in a 7-year-old girl, highlighting the presence of inflammation without true sclerosis despite normal bone age and negative fungal tests.

This study investigated a fat grafting technique (MID BACK) to enhance back muscle definition in patients undergoing liposculpture, reporting no adverse events and only minor complications, suggesting the method is safe and effective for improving muscular contours and correcting spinal asymmetries.

This study reported that appendices disorders, primarily acne and androgenic alopecia, were the most common skin diseases among patients in Sari, Mazandaran, North of Iran.

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 chapter reviews secondary soft tissue revision surgeries for residual defects in patients with orofacial clefts, highlighting the various aesthetic issues and their surgical management after reaching skeletal maturity.

This discussion of age-related changes in female scalp hair follicles reports no new results, highlighting the structural transformations that may contribute to thinning hair in women as they age.

This review emphasizes aesthetic principles for achieving a masculine look in male periorbital rejuvenation, specifically focusing on the upper eyelid, lower eyelid, lateral canthus, and brow, but reports no new clinical results.

In this study, aged mice showed better regenerative skin outcomes than young mice, linked to a specific fibroblast subpopulation and enhanced signaling interactions that promote regeneration. EREG treatment improved young mice's skin regeneration, suggesting potential for scarless therapies.

This study found that combining Aliaxin® Global Performance with Viscoderm® Skinkò E improved hydration and appearance of nasolabial folds more effectively than using Aliaxin® Global Performance alone.

As skin ages, it gets thinner, paler, and more wrinkled, and protection and care like sunblock and moisturizers are important.

This study found that polysulfonic acid mucopolysaccharide may reduce skin scarring in rats by influencing the TGF-β1/Smad signaling pathway.
