The dielectric properties of skin damage and its correlation to free radical intensity caused by UVA/UVB radiation impact

Abstract

The dielectric property in form of dielectric constant of material is a measure of material's response to a given electric field. Electric fields induce conductive and polarizing currents based on their effect on free charge attached to biological material. This phenomenon occurs at all levels of organization including cellular, molecular and ionic. When the skin is exposed to ultraviolet radiation there will be a series of chain processes that cause emergence of Reactive Oxygen Species (ROS) in the tissue. Reactive Oxygen Species (ROS) in tissue will be very dangerous because it can cause damaging free radicals. Excessive exposure to UVA/UVB radiation causes various kinds of damage which affect the low dipole moment and polarity of cells that make up skin tissue. Dipole moment and low cell polarity will decrease the dielectric constant value of tissue which is triggered by presence of free radicals in form of singlet oxygen (1 O 2) and superoxide anion (O -∗2).
