<\/p>\n
ISO 23675:2024 involves assessing the sun protection factor (SPF), which expresses a sunscreen product's level of sun protection across the entire UV spectrum, using a multi-substrate approach (molded and sandblasted plates) on which the product has been spread and measured using a spectrophotometric method. This method allows better correlation with In Vivo results. To take account of possible photoinstability, the product was pre-irradiated before measurement.<\/p>\n

<\/p>\n
ISO 23698:2024 proposes a hybrid approach combining in vitro and in vivo tests to assess the UV protection of sunscreens, in particular their Sun Protection Factor (SPF). It uses diffuse reflectance spectroscopy (DRS) to measure UVA absorbance (320-400 nm) on the skin. To obtain a complete UV absorbance spectrum, the in vitro absorbance values are adjusted according to the data obtained via DRS, enabling the in vitro UVB absorbance to be mathematically linked to the UVA portion measured by DRS. <\/p>\n

The statistical comparison method makes it possible to compare two sun protection products in terms of ageing, batch, benchmark, etc. When checking the absorbance spectrum between a reference and a test product using an in vitro method, two important rules must be observed. First of all, compare the two products at the same time and under the same conditions, to limit measurement variability. Secondly, a three-step verification based on absorbance values, including comparison of curve shape, variability and intensity.<\/p>\n
