This review discusses environmental factors like UV radiation and smoking that affect hair health and highlights the potential role of nutrition, but it reports no new results.

Minoxidil reacts to nitrosation 7 times more than phenol, mainly due to its -NH₂ groups, leading to the creation of N-nitrosominoxidil.

This article discusses the role and potential of plant stem cell extracts in cosmetics for their antioxidant and protective effects on skin cells, reporting no new clinical results; the authors highlight ecological and sustainable production methods.

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 provides a comprehensive synthesis of skin aging research, highlighting the interplay of genetic and environmental factors, cellular mechanisms, and advances in diagnostic and therapeutic strategies, while also addressing current debates and future directions in the anti-aging field.

This study observed that using ultra-high-frequency ultrasound with 70 MHz probes effectively assessed the distribution of hyaluronic acid fillers and improvements in nasolabial fold wrinkles, with significant changes in dermal thickness and wrinkle scores maintained 24 weeks after treatment.

This article discusses the organizational aspects of the II National Academic Congress of Dermatology in Brazil and reports no new research findings.

Men and women need different facial rejuvenation treatments due to distinct aging processes and anatomical differences.

This review discusses how physical appearance, including skin, facial features, and physique, is linked to aging and health risks, but reports no new experimental results.

This article reviews the skin and hair changes associated with menopause due to hormonal shifts and reports no new clinical results.

This study developed a reliable HPLC-UV/Vis method to determine aluminum phthalocyanine chloride in skin, supporting its use in skin permeation studies for photodynamic therapy of cutaneous tumors.

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 review discusses the anatomical and histological characteristics of facial fat compartments and reports no new clinical results, emphasizing a need for further research on their role in facial aging.
