although I'm not sure if that was not - is to be taken literally ... The "Sprühzeug" wears very thin on the skin, which is convenient because it does not stick and it can be spread very well and therefore - unfortunately is barely noticeable. However, I did not feel that the effect lasted for as long as you would expect at SPF 20 - anyway more of a Light version - and have repeatedly nachgesprüht diligently. In addition, the spray is packed with loads of chemicals, for example. Also MikroPlastik so that you do not know as a naive user, what is done to his skin.
I'd buy more of these reasons rather not - where it really more of a "first among equals" among comparable products, so is rather above. But for me and my loved ones I choose rather the biovar and also pay one or two euros more!
