I usually use a locally made tanning solution but wanted to try Sienna x as everyone was raving about it. I have done four spray tans using it and each one was very disappointing. While it smelled nice and it looked lovely when it first went on, the next day when it was washed off it almost vanished! I was using 10 and although I went over the odd area more than once, I was advised by someone at Sienna x that if you sprayed over an area twice it would come off the next day! Is this the case? Does anyone else find this?
