yes ubtan does stain the skin. BUT 6 days is more than enough for the colour to wear off. Ubtan has been used for centuries by women in particular to give their skin that added “glow”. It isnt bad for your skin, ofcourse each persons skin will behave differently but in general it is supposed to be good for your skin. If you are worried about the stains, you can use a lemon to get the colour out of the skin.
