Mobile phones and tablets have become the most effective communication tools especially in metropolitan cities . Exposure of the general population to radiofrequency (RF) fields from mobile phones and other communication tools has become universal and continuous in recent years . The number of mobile phone users has gone up to 5 billion in a world of 7.4 billion . Development of using mobile phones has increased concerns about the safety of health, in recent years. The studies reflected public concerns about childhood and adult cancers. The possibility that some individuals experience hypersensitivity or other symptoms in response to mobile exposure was a high priority for research .
The emitted radiation in mobile phone and tablet is electromagnetic ray in the microwave range (850–1800) [1]. Collected evidence indicates that the frequency produced by mobile phones or base stations may affect the health of the people .
The skin receives much radiation in contact with mobile phone and tablet although many studies have been carried out on the effect of electromagnetic radiation on biologic system and intracranial tumors , Diseases of the skin, especially skin cancers and contact dermatitis, are very important because of their high prevalence, chronic nature of the disease, and high impact on the quality of life (skin diseases cause pain and discomfort in 21% to 87% of the affected people) . Skin diseases allocated high burden of disease (rank eighteenth) in all age groups
Among the factors that are related to skin diseases, less attention has been paid to environmental factors. Most studies have been done on these factors, in animals. The results indicate that exposure to radiation emitted by mobile phones caused skin changes in rats, as, increased thickness of surface layer, atrophy of epidermis, deep layer proliferation, vascular proliferation, impairment in collagen tissue and protein expression in human skin in proteomics approach.
The lack of studies on the association between mobile phone use and risk of skin diseases prompted us to examine these associations in this systematic review.
