Yes Geeg, Jeni has posted on the previous page that it is advised seven days, which prompted my question.
As I said I have not used it on toes, but I agree with HF in that it must be down to the condition or dryness of the toes, especially as her client has had the two different brands with two different outcomes. I'm guessing (which I don't like doing!) that it is the chemical make up of V that grabs the nail in a completely different way to regular polish in order to eliminate the need for base case. As this seems the only variable so far.
