  • Patent number: 7892523
    Abstract: The invention relates to a cosmetic method, whereby skin is treated with various sun products, and to a sun product combination. The inventive method is characterized by applying, prior to intensive exposure of the skin to UV radiation, a pre-sun product, then a sun product and finally repeatedly applying an after-sun product.

  • Patent number: 7567080
    Abstract: The invention relates to a method for determining an integral sun protection factor (? SPF or iSPF) which encompasses both UVA and UVB radiation and can be used for classifying cosmetic and dermatological sunscreens. The method comprises the steps of applying a defined amount of the sunscreen onto a defined area of a skin substrate impregnated with a spin trap, exposing the skin substrate to a defined amount of UVA- and UVB rays by a sun simulator, subjecting the skin substrate exposed to radiation to an electron spin resonance (ESR) measurement, recording the number of free radicals trapped as a real number×1012 free radicals/mg of skin sample, and determining the integral sun protection factor ? SPF according to the equations (1) and (2) and (8) ? S ? ? P ? ? F = E 0 E ( 1 ) log 10 ? ( E ) = a · log 10 ? ( X · 1000 ) + b ( 2 ) E = 10 log ? ? 10 ? ( E ) .
