This study found that glycolic acid treatment reduced oxidative stress and inflammation in UV-induced skin photoaging in rats, promoting collagen recovery and reducing photoaging signs, potentially by inhibiting the PI3K/Akt and NF-κB pathways.

This study found that phenylbutazone and fluocinolone acetonide have similar anti-redness effects in both haired and hairless animals, making hairless rats a potential alternative for testing without needing depilation.

This study found that Hydroxypinacolone Retinoate (HPR) may alleviate UV-induced skin photoaging by enhancing collagen synthesis, reducing degradation, and modulating inflammatory and oxidative responses in a dose-dependent manner.

This study found that UV radiation-induced fibroblast depletion in the skin is primarily due to a deregulated inflammatory response, with T cells aiding fibroblast survival under stress.

In this mouse study, UVA and UVB exposure led to hair follicle miniaturization, graying, and prolonged hair cycle duration, associated with changes in stem cells and increased Wnt signaling activity.

This study found that fibroblast loss in the upper dermis from UVR exposure is linked to a deregulated inflammatory response, with T cells playing a protective role in fibroblast survival.

This study found that chronic UVR exposure in mice and humans leads to a permanent loss of papillary fibroblasts in the upper dermis, which is associated with changes in the extracellular matrix.

This study found that applying topical thymidine dinucleotide (pTT) to newborn mice before UV exposure delayed and reduced melanoma development compared to untreated controls.

Aging skin is affected by inflammation, reduced stem cell function, and slower wound healing.

This study found that a single high dose of oral vitamin D reduced UV-induced skin erythema and inflammation in humans by enhancing autophagy, suggesting new clinical avenues for skin repair.

In this laboratory study, researchers reported that Camellia sinensis seed flavonoids significantly reduced oxidative stress and inflammation in UV-irradiated skin cells by modulating key signaling pathways, highlighting its potential as a skincare ingredient for anti-inflammatory and anti-photoaging benefits.

This study found that exosomes from human umbilical cord mesenchymal stem cells reduced oxidative stress and inflammation in UVB-induced skin injury in cell and mouse models, suggesting their potential for treating UV-damaged skin by influencing Nrf2 and NF-κB pathways.

In this study, researchers used a human skin organoid model to show that solar UV exposure damages hair follicles and skin, while exosomes from mesenchymal stem cells reduced inflammation and supported hair follicle regeneration.

This study found that the loss of papillary fibroblasts in the skin due to UV radiation is mainly caused by an uncontrolled inflammatory response, with T cells helping fibroblast survival.

This review focuses on the role of exosomes in diagnosing and treating various dermatological diseases, emphasizing their potential to promote skin regeneration, improve cosmetic outcomes, and modulate immune-related conditions, with the anticipation of expanded future applications.

This review discusses the role of oxidative stress and reactive oxygen species in the development of androgenic alopecia and reports no new clinical findings.

This study confirmed the antioxidant role of rosemary, suggesting its potential use in treating inflammatory and infectious skin conditions, but emphasizes that more large-scale controlled trials are necessary to fully understand its clinical impact.
