This study found that, despite confirming MC1R expression and functional cAMP signalling, α-MSH treatment did not alleviate UVA-induced stress in adult dermal fibroblasts, suggesting that α-MSH-MC1R may not directly protect against UVA-induced photoaging in these cells.

This study found that photoexposure significantly increased the gene expression of altered elastin, MMP12, and LOX, as well as the protein expression of tropoelastin and fibrillin-1, in skin models.

This study in transgenic mice found that the combination of SPF 15 sunscreen and a UVA filter provided strong protection against UVA-induced elastin promoter activation and thus may reduce photoaging.

This review discusses the potential benefits of topical melatonin in aesthetic dermatology, including its antioxidant and protective properties for skin aging and photoaging, while also noting varying strengths of evidence across different skin conditions.

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.

This study found that chronic ultraviolet-B exposure increased skin vascularization and wrinkle formation in mice, while overexpressing the angiogenesis inhibitor thrombospondin-1 reduced these effects, suggesting angiogenesis inhibition as a potential approach to prevent photo-damage.

This article reviews the dermatological challenges and cultural influences affecting India's aging population, noting that while pigmentary disorders and cosmetic dermatology are prevalent, cutaneous cancers remain rare and often go undetected.

In this study, topical red onion ethanol extract significantly restored cutaneous antioxidant and pro-angiogenic markers in UV-B-exposed rats, enhancing SOD and VEGF levels dose-dependently, but did not influence hair length, suggesting potential as an adjunct for hair photoaging.

Some treatments like topical oxygen and stem cells show promise for wound healing and hair growth, but evidence for modern dressings over traditional ones is limited.

In this study, exosomes were identified as influential in skin biology, demonstrating potential in accelerating wound healing by modulating inflammation and enhancing tissue regeneration, though their use remains primarily cosmetic pending FDA approval.

Aging affects hair density and skin health, and Behcet's disease, a complex condition with no specific test, involves sores and systemic issues, treated with various medications.

This review discusses the fundamental hallmarks of aging as they relate to skin aging and highlights the prominent roles of oxidative damage and the extracellular matrix in photoaging, reporting no new results.

This research outlines how retinoids, compounds based on vitamin A, activate nuclear receptors to influence cellular processes such as differentiation and carcinogenesis, with benefits like anti-inflammatory properties but requiring careful management of dose-dependent side effects.

This study found that combining red light therapy with oral beta-carotene significantly improved photoaging treatment outcomes compared to red light therapy alone, with Group A showing a 56.12% reduction in photoaging scores over 12 weeks versus 44.78% in Group B.

This review summarizes the clinical characteristics of Behcet's disease, noting that ocular manifestations are a major cause of morbidity due to their potential to lead to severe vision loss or blindness.

This review reports that natural compounds show promise in slowing skin photoaging by targeting cellular pathways in keratinocytes and fibroblasts. However, comprehensive clinical studies are needed to verify their efficacy and safety.

This review explores how various skin cell types contribute to photoaging driven by UV radiation, detailing their interactions and molecular mechanisms like oxidative stress and ECM degradation, ultimately offering insights for future anti-photoaging strategies.

This review highlights that exosomes from adipose-derived stem cells, particularly those enriched with circ-Ash1l, can inhibit ferroptosis and reduce UVB-induced skin aging by delivering GPX4-promoting signals to damaged cells, thus offering a potential regenerative therapy for photoaged skin.

This review discusses the potential of endogenic and exogenous exosomes in dermatology and cutaneous aesthetics, highlighting their capacity to repair and rejuvenate skin tissue, but reports no new experimental results.

This article reviews treatment options for cutaneous T-cell lymphoma, including skin-directed therapies and aggressive treatments for advanced cases, but reports no new clinical results.

This article discusses the technique of laser Doppler velocimetry for measuring cutaneous blood flow and does not report new research findings.

This review highlights evidence supporting the potential of blue light therapy as a non-invasive treatment for managing skin and hair conditions by modulating interactions between the skin microbiome and its host.

In this study, tempeh oil rich in PUFAs, particularly from black soybean, significantly down-regulated MMP-9 gene expression in UVB-irradiated mice skin, indicating potential for use in preventing skin photoaging.

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 UVB irradiation alters skin stem cell niches leading to signs of photoaging, which may be reversed by adipose-derived stem cells through BMP4 pathway modulation and niche remodeling.

In this study, combining microneedle and sublative fractional radiofrequency treatments significantly improved skin tightening, texture, collagen organization, and satisfaction in individuals with moderate photoaging, while reducing abnormal elastin after three months.

In this descriptive study, elderly patients most commonly presented with skin wrinkling, xerosis, and eczematous conditions, highlighting the difficulty in distinguishing normal age-related from pathological skin changes.

In this study, the Peninsula Timerevert Needle was found to provide effective treatment for skin photoaging and acne scars with less pain and shorter treatment duration compared to EndyMed, although it caused more bleeding.

This paper reviews the role of the telomere-telomerase system in cellular ageing and cancer, discussing potential therapies but reporting no new experimental results.

This study observed that among elderly patients, the most common systemic disease associated with skin conditions was diabetes, while wrinkling and xerosis were prevalent skin changes.
