Hi all normally on nails geek but I am booking in my Tantrick Training tomorrow with Vanessa and I was wondering how long can you keep the solution for, I have just ordered a litre of 5% I have got 5 models and two are quite dark so I am now thinking of getting the 10% as well, but don't want to be left with loads of the 10% as most of the people who I will be tanning are pale.
Thanx for any help.
