An oxidative damage in cell structures is a basis of most mechanisms that lead to health diseases and senescence of human body. The presence of antioxidant issues such as redox potential imbalance in human body is a very important question for modern clinical diagnostics. Implementation of multispectral and colour analysis of the human skin into optical diagnostics of such wide distributed in a human body antioxidant as ubiquinone can be one of the steps for development of the device with a view to clinical diagnostics of redox potential or quality control of the cosmetics. The recording of multispectral images of the hand skin with monochromatic camera and a set of coloured filters was provided in the current research. Recording data of the multispectral imaging technique was processed using principal component analysis. Also colour characteristics of the skin before and after the skin treatment with facial mask which contains ubiquinone were calculated. The results of the mask treatment were compared with the treatment using oily ubiquinone solution. Despite the fact that results did not give clear explanation about healthy skin or skin stressed by reactive oxygen species, methods which were described in this research are able to identify how skin surface is changing after the antioxidant treatment. In future it is important to provide biomedical tests during the optical tests of the human skin.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the proceedings. They include the speaker's narration with video of the slides and animations. Most include full-text papers. Interactive, searchable transcripts and closed captioning are now available for most presentations.
