HOLY GRAIL sunless tanner for me (and I am faux-tanned almost all year long). I use the VERY DARK shade. It is amazing on my OLIVE skin, which can look quite "muddy" if I use very neutral-brown toned sunless tanners. My olive skin tone either needs a very golden-coppery sunless tanner OR it needs a sunless tanner with a bit of reddish-bronze in it (that is what this sunless tanner has). The red tone is very slight -- just enough to make the tan result look more natural, the way it would look if I really laid out in the sun. When I use to lay out (which I haven't done in over 20 years), my first day suntanned skin would have that gorgeous slightly sun-burnt rosy-bronze color to it (SO bad for the skin! but so pretty!). I have tested a ton of sunless tanners of the past 20 years, searching for that same reddish-bronze type of glow in a bottle, but had not been able to find one --- until I discovered SUN Laboratories. I cannot comment on the other shades in this line, as I have only tried the VERY DARK. (My 2nd fave sunless tanner is Fake Bake, but FB is much more of a toned down "tan" color. It's more golden-brown (no copper or red tones in it at all). I usually reserve FB for my body, but never my face -- as it can give me that muddy "2 week and fading tan" look, which I hate. SUN Labs' tan is much more vibrant, yet still very natural looking (just the way cool/neutral toned olive skinned brunettes would tan naturally).
The only down side to this product for me is that the pump top came off very easily, and no longer stays on very well. The slightest touch causes it to fall off (it "locks" if you don't have it turned in just the right spot, which is fine if the top of the pump would stay on!).
Unlike Fake Bake, SUN Labs does not include gloves or a mitt. I would highly suggest you use gloves, at least. I use the gloves and mitt from my Fake Bake for all of my sunless tanner applications. This product will stain your hands and nails if you don't wear gloves and do not wash your hands immediately.
Overally, this is a MUST HAVE sunless tanner for all those with olive skin who find other sunless tanners either too flat/muddy/taupe brown, or find sunless tanners to be too orange.
