Kobrlová, Petra ; Doležal, Pavel (advisor) ; Vachek, Josef (referee)
The work summarizes information about the basic functions of the skin, its structure, aging and rejuvenation cosmetological methods. An overview of findings from the instrumental treatment of the skin using Intensive Pulse Light (IPL) and fractional CO2 laser and a short survey of objectification cosmetic effects using instruments for sebumetry, frictometry and visiometric texture determination. The experiment is focused on the evaluation of effects of cosmetics creams Liftaktiv CxP Vichy and Vichy Neovadiol Gf, and the use of IPL and fractional CO2 laser rejuvenation methods in relation to selected physical properties of the skin, specifically the content of skin lipids, skin friction and skin texture. 9 women of three age categories were chosen for the experiment. Visia Imaging System (Canfield Imaging System) and CK Electronic Analyser (Courage-Khazaka) were used for evaluation of qualitative changes of the skin. Results were obtained through sensory tests with expert control and instrumental measurements with expert evaluation (Colipa 2008) of the observed data in context with other information about clients. A qualified assessment of impact of the random and systematic effects was given. An illustrative statistical evaluation of skin friction as the one selected variables helped to formulate...
