After qualifying I tried lots & lots of different solutions and these 2 solutions were my joint number 1.
In the end I decided to go with LA Tan. I love everything about it and it was that little bit cheaper than Nouvatan. The deciding factor for me was price as everything else got ticks for both solutions - fab colour on the tans, lasted well, faded nicely, smelled nice when spraying, dried fast, great customer service etc..
If you have not already get some samples and try them out and make your choice from there. If like me you already sampled them and it is a draw between them then I know that whichever you choose you will be happy as will your clients. I know that IF I had to change my solution for any reason I would be buying Nouvatan without a doubt.
