In this study, oral administration of Lactococcus lactis strain H61 to senescence-accelerated mice was linked to reduced bone density loss, less skin ulcer incidence, and reduced hair loss, along with altered immune responses.

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 review discusses the relationship between estrogen deficiency and skin aging in postmenopausal women, noting potential benefits of estrogen use on skin collagen and elasticity, but reports no new clinical results.

This study validated a facial aging scale that predicts patients' age with good reliability and validity, potentially serving as a useful tool for assessing facial rejuvenation treatments and clinical research.

In this study, researchers found that exposure to PM10 significantly increased inflammation and impaired collagen synthesis in human dermal fibroblasts, suggesting PM10 contributes to skin aging through these mechanisms.

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.

This study details how very long human hair naturally ages, showing cuticle wear and internal fiber changes that may inform new hair care product designs.

This study suggests that age-related changes in skin elasticity reduce its stability against wrinkling, and anti-aging strategies should focus on addressing elastic mismatches between skin layers.

In this study, a new apple stem cell extract serum significantly improved signs of skin aging and enhanced cell metabolism in human senescent fibroblasts, showing visible effects after one week of use.

This review addresses the role of skin-resident adult stem/progenitor cells in skin homeostasis, disease, and cancer development, and reports no new research results.

This study found that loading CoQ10 into a protransfersomal emulgel improved its stability and anti-ageing effects in UV radiation skin-aged induced-mice, without causing skin irritation.

This review explores how cell and mouse models have contributed to understanding the mechanisms of human aging, particularly focusing on Hutchinson-Gilford Progeria Syndrome, and reports no new clinical results.

This study found that a novel proniosomal gel formulation of CoQ10 improved antioxidant levels and provided better skin protection against UV radiation compared to a conventional CoQ10 gel in animal models.

This study found that conditioned media from epidermal progenitor cells improved skin aging signs in a clinical trial and protected fibroblasts from oxidative stress in vitro.

This review discusses the mechanisms by which sunlight exposure aggravates hair aging and highlights the role of hair pigments in providing photochemical protection, reporting no new results.

This review discusses the role of defensin peptides in stem cell activation for potential skin rejuvenation therapies and reports no new clinical findings, emphasizing the need for further studies.

This article reviews the biological causes and treatment options for facial aging but reports no new clinical findings.

This review discusses age-related changes in scalp skin and their potential effects on hair follicle aging, but reports no new clinical results, calling for further investigation.

This review found that among emerging technologies for skin anti-aging, stem cell therapies using recipient chimerism might be more beneficial than CRISPR-Cas9 and other current innovations, though further studies on safety and efficacy are needed.

This review analyzed 12 clinical studies on extracellular vesicle therapies, finding potential benefits for skin aging, acne scars, alopecia, and wound healing, but highlighted significant challenges like production standardization and lack of large-scale studies.

The researchers reported that miR-21 expression increases with age in both human and mouse skin and may contribute to skin aging by targeting the chromatin remodeler SATB1 in keratinocytes.

This review highlights the role of the receptor TLR4 in cellular aging and age-related diseases, suggesting it as a potential therapeutic target due to its contribution to persistent inflammation and symptom regulation in these conditions.

This study assessed 11 plants from French Polynesia for their potential development as sustainable natural cosmetics, particularly anti-aging and hair care products, based on their traditional uses and preliminary screening results.

This study reports that the tetrapeptide AcSDKP significantly promotes skin and hair health in vitro and ex vivo, suggesting it could be used cosmetically to counteract skin aging and hair loss.

This study reports that a wide variety of patients utilize anti-aging treatments, are largely unfamiliar with their options, and are more likely to pursue treatment if informed by a dermatologist.

This review discusses the potential for new retinoids, topical antiandrogens, and alternative therapies to surpass tretinoin in treating cutaneous aging, but reports no clinical results.

This study found that berry extracts, especially black raspberry extract, may have anti-aging effects due to their high antioxidant activities.

This review discusses the role of collagen XVII in maintaining stem cell niches and its impact on skin aging and wound repair, without reporting new clinical results.

This study observed that estrogen receptor β and androgen receptor expressions in the skin decline with age, more noticeably under sun exposure, suggesting a role in skin aging.

This symposium reviewed various advances in understanding and potentially reversing skin aging, with no new experimental results reported.
