Background: Skin photoaging is a condition caused by long-term exposure to ultraviolet irradiation, resulting in a variety of changes in the skin, such as capillary dilation, increased or absent pigmentation, dryness, sagging, and wrinkles. Stem cells possess a remarkable antioxidant capacity and the ability to proliferate, differentiate, and migrate, and their main mode of action is through paracrine secretion, with exosomes being the primary form of secretion. Stem cell-derived exosomes contain a variety of growth factors and cytokines and may have great potential to promote skin repair and delay skin ageing.
Methods: This review focuses on the mechanisms of UV-induced skin photoaging, the research progress of stem cell exosomes against skin photoaging, emerging application approaches and limitations in the application of exosome therapy.
Result: Exosomes derived from various stem cells have the potential to prevent skin photoaging.
Conclusion: The combination with novel materials may be a key step for their practical application, which could be an important direction for future basic research and practical applications.

Inflammaging has long been linked to the pathogenesis of various aging-associated disorders, including cardiovascular disease, obesity, type 2 diabetes, and dementia. Yet, the origins of inflammaging remain unclear. Although inflammatory dermatoses such as psoriasis and atopic dermatitis predispose to the development of certain aging-associated disorders, suggesting a pathogenic role of cutaneous inflammation in these disorders, the great majority of aged humans do not have inflammatory dermatoses.

Background: Aging reduces the production of hyaluronic acid (HA) in the skin, leading to wrinkles and sagging. HA-based skincare products are being studied to improve skin quality. This systematic review and meta-analysis aimed to compare the effectiveness of HA-based injectable products for reducing wrinkles and enhancing skin elasticity, hydration, and radiation.

Cutaneous photoaging, induced by chronic exposure to ultraviolet (UV) radiation, typically manifests as alterations in both the physical appearance and functional properties of the skin and may predispose individuals to cancer development. Recent studies have demonstrated the reparative potential of exosomes derived from mesenchymal stem cells in addressing skin damage, while specific reports highlight their efficacy in ameliorating skin photoaging. However, the precise role of exosomes derived from human hair follicle mesenchymal stem cells (HFMSC-Exos) in the context of cutaneous photoaging remains largely unexplored.

Background And Aim: A critical causative factor of oxidative stress and inflammation leading to several skin complications is ultraviolet-B (UVB) irradiation. (LR), or tiger milk mushroom, is native to Southeast Asia. Cold water extract of an LR cultivar, TM02® (xLr®) is a promising anti-oxidant and anti-inflammatory source.

Introduction: Hand rejuvenation addresses aging-related changes such as subcutaneous fat loss, skin degradation, and photodamage. Autologous fat transfer (AFT) has emerged as a promising treatment, offering durable volume augmentation and regenerative effects. This study aims to systematically review the evidence on the techniques, outcomes, and complications of AFT for hand rejuvenation.
