Today’s consumers are increasingly attracted to sunscreen products that can be applied at any time and to all skin types, even after swimming. \nApplication to wet skin is no exception, and refers to the ability of sun protection products to be applied directly to wet skin, for example immediately after getting out of the water, with a guarantee of even sun protection and without the appearance of a white effect, thus offering optimum practicality and effectiveness, while meeting the needs of active users. In other words, it allows the user to skip the step of drying the skin before applying sunscreen.<\/p>\n
In order to determine and justify this claim of product efficacy when applied to wet skin, WENEOS has developed an exclusive in vitro method based on the comparison of the sun protection factor (SPF) on a dry and then wet substrate, and on the calculation of the percentage of wet skin, thus guaranteeing a rigorous and reliable assessment.<\/p>\n

We can assess the sun protection of your products in full compliance with official methods, or claim the properties of your products through exclusive tests developed by WENEOS.<\/p>\n<\/blockquote>\n
WENEOS has developed a new in vitro method to reliably determine the ability of a sunscreen product to retain its sun protection when applied to damp skin. This method is based on comparing the sun protection factor (SPF) on a dry and then a wet substrate, and on calculating the percentage of wet skin.<\/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
In this method, a specific step for comparing the resistance of the two products can be added, such as water resistance, friction resistance, etc.<\/p>\n
