Not a bad idea, but not convinced 100% plus questionable ingredients

The Nivea Sun In-Shower has the same principle as the Nivea In-Shower Body Milk. Say, shower off, rub the lotion soak briefly and finished. Actually sounds pretty easy and well, especially after I no unpleasant greasy film on the skin have. However, convinced me the product is not 100%, since the effect is not 100% - I say now - coverage occurs. As would be - purely theoretical - a bath almost better suited for. The problem: When showering you can reach not all sites (keyword: back). Especially when camping or in the swimming pool which is rather inappropriate, since in the separated men showering my wife yes logically has no access and I am not really keen to talk a strange man if he wants to put some cream my back.
Apart from this - after all, would be the After Sun In Duschlotion yes are at least for holidays in apartments or for use at home, the ingredients are still negative memories, because, among other things contained paraffins and polymers.
I prefer to stay with my moisturizers and possibly after sun lotions, which I can easily use when needed.
