Sunscreens: Evolving Aspects of Sun Protection

      Excess sun exposure can lead to deleterious sequelae, such as skin cancer, photoaging, immune suppression, and exacerbation of phototoxicities (

      Broad-spectrum sunscreens provide better protection from solar ultraviolet-simulated radiation and natural sunlight-induced immunosuppression in human beings.

      ). Sun protection is critical for the pediatric age group, because studies have shown that the amount of sun exposure during this period is related to subsequent risk of melanoma and other skin cancers (

      ). This finding is significant because the number of children who experience sunburns is staggering. One study demonstrated that 83% of children become sunburned during the summer, and approximately 36% of adolescents have repeated sunburns during the summer (

      ). Subsequent statistics regarding ultraviolet (UV)-related skin cancer are even more troubling. Within the United States, more than 1.3 million new cases of squamous cell and basal cell cancer occur every year, and more than 90% of these cases are caused by overexposure to UV radiation (

      ). In 2009, the American Cancer Society reported that skin cancer was the most common form of cancer in the United States and that the incidence of new cases of skin cancer per year is greater than the combined incidence of breast, prostate, lung, and colon cancer. This morbidity has resulted in substantial health care costs, as statistics from 2004 have shown that direct costs for treating non-melanomatous skin cancer were estimated to be greater than $1 billion, and greater than $2 billion when indirect costs were included (
