摘要
Produciton of free radcal the human skin subse quent to IR irradion has been demonstrated by means of two different methods. THe frist technique based on resonance. Raman spectroscopy enables the non invasive measurements of the metics of cutaneous carotenoid antioxidants beta-carotene and lyeopene subsequent to IR irradation. Obtained degradation of the cutaneous carotenoids was a hint but not evidence that IR irradiation can produce fre radicals in the skin. Therefor the direct observation sustaining the production of free radicals subsequent to IR irradiation in the skin was performed in vitro by electron paramagnetic resonance spectroscopy. Enzymatic processes as well as heat shock-induced radicals in the human skin are pre-sumably involved in the energy transfer from IR irradation into the molecules of the skin protection strategy for human skin against IR-induced free radicals based on the increase in the concentration of antioxidants by means of antioxidant-rich supplementation is discussed
