Abstract: Back ground: Ultraviolet (UV) radiation is a known carcinogen․ The two types of UV radiation that affect the skin are known as ultraviolet A (UVA) and ultraviolet B (UVB)․ Both have been linked to skin cancer and an overall weakening of the immune system․     UVB rays mostly affect the surface of the skin and are the primary cause of sunburn․ Overexposure of UVB causes cellular damage in the basal and squamous layers of the skin, and is the main cause f basal cell and squamous cell...

Abstract: Back ground: Ultraviolet (UV) radiation is part of the electromagnetic (light) spectrum that reaches the earth from the sun․ It has wavelengths shorter than visible light, making it invisible to the naked eye․ Ultraviolet A (UVA) is the longer wave UV ray that causes lasting skin damage, skin aging, and can cause skin cancer․ Ultraviolet B (UVB) is the shorter wave UV ray that causes sunburns, skin damage, and can cause skin cancer․ Result:  Sunscreens are products combining...
