Ultraviolet (UV) radiation is a ubiquitous component of the environment that has important effects on a wide range of cell functions. Short-wavelength UVB radiation induces sunburn and is a potent immunomodulator, yet longer-wavelength, lower-energy UVA radiation also has effects on mammalian immunity...
UVA (Ultraviolet A):This Ultraviolet light comes with longer wavelengths and is associated with aging skin. Indeed, it is one of the least harmful. However, it can contribute to skin aging and wrinkles. UVB (Ultraviolet B):UVB is a dangerous ray with medium wavelengths. People often know it...
