Aged skin heals slower due to more inflammation and disrupted cell communication.

Aged skin cells can help hair growth by stimulating stem cells.

This study found that RCS-01 cell therapy for aged skin was well tolerated and associated with increased gene expression related to extracellular matrix homeostasis, suggesting potential skin improvement.

This study observed that nearly all aged nursing home residents in Berlin had at least one dermatological condition, with xerosis cutis being the most common, but few associations with demographics or medical characteristics were found.

In this study, intradermal injection of GCSF-mobilized peripheral blood stem cells from young pigs rejuvenated skin in aged pigs by increasing collagen, elastin, and cell renewal rates.

This study suggests that the exercise-induced cytokine IL-15 can improve wound healing in aged skin, along with previously reported benefits on skin structure and mitochondrial function.

This study found that in mice, type XVII collagen is essential for controlling epidermal cell proliferation through Wnt signaling, with its deficiency or altered distribution leading to skin hyperproliferation and aging-like changes.

This study concluded that hair-derived stem cells from older donors may offer a promising alternative for autologous corneal endothelial replacement, potentially benefitting patients of various age groups.

This study found that nearly 80% of Finnish adults aged 70 to 93 had at least one skin disease requiring treatment, with men more affected than women.

This study reported that atelocollagen enhances collagen synthesis and reduces oxidative stress in aged skin by increasing glycine uptake through GlyT1, resulting in improved skin elasticity and collagen density in aged mice, with effects superior to glycine alone.

This study found that a cell therapy product, RCS-01, was well tolerated in aged skin and led to significant increases in gene expression related to extracellular matrix homeostasis, although the small cohort size limited further efficacy analysis.

This study found non-melanoma skin cancer in 7.2% of elderly residents in long-term care facilities in Berlin, highlighting the need for more routine skin cancer screenings in these settings.

This study found that Tideglusib enhances wound healing in aged rats by activating the PI3K/Akt pathway, suggesting its potential for medical and cosmetic applications targeting age-related skin changes.

This study reports that a single intradermal injection of autologous adipose-derived stem cells improved visible aging signs such as wrinkles and pore size on facial skin for over a year in eight patients, with in vitro data suggesting muscle involvement in the rejuvenation process.

This study described two cases of trichoblastomas in the tactile hair skin of aged house musk shrews, highlighting that their histological structure differs from that in humans and other animals.

In this study, hyaluronic acid filler injections in albino rats increased subcutaneous tissue thickness, collagen and elastic fibers, and vascularization, suggesting potential benefits for combating skin aging and defects.

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.

Hedgehog signaling helps keep hair follicle stem cells the same in both young and old human skin.

This ex vivo study reported that melatonin significantly improved certain aging biomarkers in aged human skin, including reduced mTORC1 activity, increased fibrillin-1, and enhanced collagen and elastic fiber organization, though other key biomarkers remained unchanged.

In this study, PDLLA treatment in middle-aged mice was observed to enhance hair growth by increasing macrophage M2 polarization and hair follicle stem cell proliferation, potentially rejuvenating the skin's microenvironment and offering a novel approach for age-related hair loss.

This case report describes a middle-aged man with niacinamide-induced poikilodermatous flushing observed on the neck, established through clinical and dermatoscopic evaluation.

Inherited ichthyosis negatively impacts quality of life, affecting daily activities, self-image, and reproductive decisions.

This study observed that extracellular matrix scaffold membranes performed less effectively in wound healing for aged mice compared to younger ones, with senescent SPP1+ macrophages potentially hindering epidermal and fibroblast repair abilities.

This study found that adiponectin significantly enhanced lipid production in human sebaceous glands and may be a potential target for treating conditions with reduced sebum production.

This study reviews the use of nanofat in facial rejuvenation and cosmetic surgery, highlighting its potential for improving skin appearance and treating conditions like wrinkles and acne scars, yet emphasizes the need for further research into its long-term efficacy and safety.

This study found that both genetic and epigenetic factors significantly influence age-related facial skin aging, with lifestyle and environmental factors also playing a substantial role.

This study observed that aged dogs exhibit atrophy of the epidermis, appendages, and dermis, along with variable skin changes and increased dermal pigmentation, but lack senile elastosis seen in humans.

This case report details a middle-aged man with multiple sclerosis who developed difficult-to-evaluate skin reactions after daclizumab treatment, noting only slight improvement with additional therapies.

This study found that targeting IL-17 signaling in aged skin reduces inflammation and delays age-related traits, suggesting a potential strategy to prevent age-associated skin ailments.

This study observed that in aged mouse skin, there was an increase in IL-17-expressing T helper cells, γδ T cells, and innate lymphoid cells, and blocking IL-17 signaling reduced skin inflammation and delayed age-related changes, suggesting it as a potential target to mitigate skin aging.
