I haven't searched so not sure if anyone has already done this but I am just in the process of trialling the 2 hour Viesha tan (20%). Thought I'd upload photos of guide colour, just after wash off and then 24 hours after. Will take the photos in the same room with the same lights so will be as good a guide as possible. I REALLY want to leave on longer than 2 hours and I know you can depending on what results you want but I want to see how dark it is just with the 2 hours development time.
My first thoughts are, lovely smell (husband says it smells like a nice shampoo, apparently Pantene Pro-V??? Wtf lmao!!), love the guide colour. I use Nouvatan and the Viesha guide colour is slightly darker (husband also says he likes it lol - he is the one who sprays me btw). Also, its not terribly sticky I'd say its the same as Nouvatan in that sense. I was sprayed half an hour ago so I am still aware of it on my skin at the moment but it is by no means uncomfortable. Photo below is straight after application. It's a close up as I don't want to put my fat rolls on here ha ha ha!! Will upload another pic in a couple of hours x
