Having read numerous threads in the past on this subject in the hope of finding "the one" (to replace Lancôme's infamous Flash Bronzer for Face) I think I've finally found it!!
Gatineau Golden Glow Gradual Tan Face Serum is its name. I saw it advertised on FB and ordered a trial 10ml tube for £8. You only need a small amount so it's lasting me very well but I will be splashing out on the full size one. It's lovely to apply as it's a skincare serum as well as gradual tanner. It dries pretty quickly so you don't have to wait around too long to apply moisturiser etc and it gives you a lovely glow! I went for the Medium/Dark as reviews suggested the light one isn't as effective.
I don't work for them I promise - just wanted to share the find.
