The Molecular Mechanism of Polyphenols with Anti-Aging Activity in Aged Human Dermal Fibroblasts

The skin, as the body’s largest organ, consists of three layers: the epidermis, dermis, and hypodermis. The dermis contains dermal fibroblasts and an extracellular matrix, including collagen and elastin, which are crucial for skin’s elasticity and firmness. Skin aging is accelerated by environmental factors such as UV radiation, pollution, and smoking through the generation of reactive oxygen species and related signaling pathways. These factors contribute to reduced elasticity, wrinkle formation, and slower wound healing. Research has indicated that natural polyphenol compounds can slow these aging effects by modulating signaling pathways in aged dermal fibroblasts. This paper examines the links between aging and its molecular mechanisms and explores how various polyphenols can enhance skin health, providing valuable insights for the development of functional cosmetics and potential clinical applications.

Impact of Ketogenic and Low-Glycemic Diets on Inflammatory Skin Conditions

Diet is increasingly recognized as a tool in dermatologic treatment, with ketogenic and low-glycemic diets showing promise due to their anti-inflammatory and metabolic benefits. This overview examines their effects on various inflammatory skin conditions like acne, psoriasis, seborrheic dermatitis, atopic dermatitis, and hidradenitis suppurativa. Findings suggest that low-glycemic diets are particularly effective in managing acne. […]

Ketogenic Diet and the Skin

Dietary changes, particularly the ketogenic diet (KD), which is low in carbohydrates and high in fats with adequate protein, have become a focus in dermatology for managing skin disorders. This interest is fueled by emerging research from various studies, including basic science, small clinical trials, and population reports, suggesting KD’s potential as a supportive treatment […]
