and I really had many. It should be borne only wirllich the instructions. Preferably in the evening, let it work overnight and rinse off in the morning, even if you did not before had to take a shower, so that the "Guide Color" (which is mouce tinted so you can see where you have been) is abgeschwaschen. this is usually during the day with the sweat, the one secretes inevitable, and a dirty clothes. then is no longer out. But do not worry if you have first washed the color, anything goes from white and remains white. I also find the aplikator well and also come in super clear face it. In winter I use it only once a week, so I do not look sickly-pale, but we also acts not summer-holiday-brown, which would seem somewhat unnatural in winter I think. and works great, I can only recommend. The price is also great, because the product is very economical.
