My husband sprayed my legs with Aviva Express yesterday morning, and I washed off the colour guide exactly 1 hour later, wanting to experience the shortest possible development time.
The initial result was a reasonable, very light tan, but it most certainly continued developing over the afternoon, if not evening!
Quite honestly, I would've been happy if the tan had not continued deveoping, especially as I'd purposely selected having a light tan. The final result was a very noticeable colour, not too dissimilar to the my results with Fake Bake Original.
So whilst Aviva Express, for me, did what it said on the tin, I'm finding two downsides - (1) The overall result from a 1-hour development time is not "fair" but most definitely "medium" and (2) because I behaved throughout the rest of the day as though I was wearing a fully-developed tan, I now have quite severe strap-marks from my shoes.
I think I might still splash out on a bottle though!
Am eagerly awaiting loads more peeps' opinions too
