INTRODUCTION Skin photoaging is the consequence of solar UV exposure, and DNA damage is an important part of this process. The objective of the current work was to demonstrate that in vitro skin models can be utilized to confirm that DNA damage protection is provided by sunscreens. METHODS Skin equivalents were exposed to full-spectrum UV light administered with a standard research solar simu...
Ultraviolet (UV)B irradiation induces the production of matrix metalloproteinases (MMPs) by activating cellular signaling transduction pathways, which are responsible for the degradation or synthesis inhibition of collagenous extracellular matrix in connective tissues, causing skin photoaging. Using the human skin fibroblast (HS68) cell line in the present study, we investigated the inhibitory ...
UVB-induced cutaneous photodamage/photoaging is characterized by qualitative and quantitative deterioration in dermal extracellular matrix (ECM) components such as collagen and elastic fibers. Disappearance of microfibrillar-associated protein 4 (MFAP-4), a possible limiting factor for cutaneous elasticity, was documented in photoaged dermis, but its function is poorly understood. To characteri...
Background: Skin reflects the general health status and is not an exception in the process of aging. Intervention studies indicate that it is possible to delay skin aging and improve skin conditions through diet-based anti-aging strategies. The purpose of the current work was to review recent existing literature regarding the role of nutrition, for and against skin aging processes.Method: This ...
Introduction: (259 words) Sunscreen is essential in preventing skin damage caused by harmful ultraviolet radiation. Regular and appropriate sunscreen application delays photoaging reduces cancer risk. This study aims to assess the general knowledge practice of among medical undergraduates Nepal.
Skin aging is a multisystem degenerative process that involves the skin and skin support system. Young faces tend to be convex with full lips, sweeping jaw line with full temples and cheeks. Aged face tends to be concave with flat lips, sunken temples and cheeks, scalloped mandible and more shadows. Aging caused by the genes we inherit and depending on the passage of time per se is called chron...
