Abstract

A microplasma electrode was used for skin treatment using argon, oxygen, nitrogen or ambient air. The presence of various particles is important for the interpretation of the microplasma effect on the skin. The production of long living particles was detected by an FTIR spectrometer and the presence of air between the sample and the electrode was monitored by the O₂ monitor. In the case of gases other than air, we concluded that the concentration of processing gas is at least 99.5 %. The epidermal layer of pig skin was used for observing changes caused by microplasma treatment. The XPS spectra of carbon and oxygen were analysed.
