UV Absorption Spectroscopy for the Diffusion of Plasma-Generated Reactive Species through a Skin Model

Skin applications of non-thermal atmospheric pressure plasma (NTAPP) have been at-tracting attention from medical and cosmetic aspects. The reactive species generated sources known to play important roles in the skin. For proper applications, it is essential know how they diffuse into In this study, penetration active NTAPP through a skin model was analyzed by UV absorption spectroscopy. diffusions hydrogen peroxide, nitrite, nitrate were quantified curve fitting. We utilized an agarose gel mimic epidermis dermis layers, we used lipid film or pig sample stratum corneum (SC). diffusion characteristics limitations method discussed
