Effects of infrared, blue light and UVA-II on human skin
Knowledge about environmental factors that are aggressive to skin has increased in recent years. Although concern previously focused primarily on UVA and UVB, this has broadened to contain damage from pollution, tobacco smoke, other ambient toxins, infrared light, blue light and UVA-II. This article reviews the negative effects of infrared, blue light and UVA-II on skin. Potential protective a...
متن کاملNrf2-mediated protection against UVA radiation in human skin keratinocytes.
Ultraviolet A (UVA, 320-400 nm) radiation is an oxidizing agent that causes significant damage to cellular components and that leads to photoaging and cancer. It strongly induces NF-E2-related factor 2 (Nrf2) expressions in cultured FEK4 human skin fibroblasts but weakly induces it in transformed HaCaT skin keratinocytes. Nrf2 silencing increases cell damage at a moderate dose of UVA irradiatio...
متن کاملEffect of melatonin on human keratinocytes and fibroblasts subjected to UVA and UVB radiation In vitro.
Skin represents one of the extrapineal sites of melatonin (Mel) synthesis. In the skin Mel plays, for example, the role of an antioxidant which scavenges and inactivates free radicals arising due to UV irradiation. Although the protective effect of Mel on skin and cells irradiated mainly with UVB has been documented, to date no comparison has been made for the effects of Mel on cells exposed to...
متن کاملProtective Effects of Lindera coreana on UVB-induced Oxidative Stress in Human HaCaT Keratinocytes
The present study was designed to investigate the protective effect of ethanol extracts from Lindera coreana leaves (LCE) on UVB-induced oxidative stress in HaCaT keratinocytes. The HaCaT cells were pretreated with LCE for 24 h and then exposed to UVB (20 mJ/cm2) for 2 h. UVB significantly decreased the cell viability (p
