hi i have been using ubertan for 2 weeks and it has not worked for me, i have been on a sunbed 4 times and the only colour change is what i would normally get from the sunbed, i bought this product from a local salon, when i have enquired about the results they dont seem to know much about it or if there is a money back garentee, they have told me they have sold lots of this product but cant tell me of other peoples results !
