Abstract

Skin is located on the outermost layer of body, which poses it to easy and frequent exposure to toxic chemicals, physical stimuli and environmental contaminants. Depending on the stimuli, outcomes of skin toxicity may differ, which include commonly observed, and evident skin reactions like skin burn, irritation, sensitization, phototoxicity, or photosensitivity. Less common reactions like pigmentary disorders, urticaria, and fibrosis can also occur. Effects of sunlight on the skin have been well established and with this, radiations with longer wavelength are gathering interest for their effects on the skin health. In this study, we investigated the effects of electromagnetic field (EMF) of LTE bandwidth, 1.742 GHz, SAR 6-8 W/kg on the skin by using an artificial human skin model. The results indicated that EMF exposure does not have much effect on epidermal cytotoxicity or obvious pigmentation in the skin, but it has a slight effect on skin epidermal integrity and melanocyte activation. The mechanism and the final outcome of EMF exposure should be further studied through more scientific studies and various molecular biochemical studies.
