I've had this gloss in two shades- natural and perfect red. They're both fantastic formulas- hydrating-ish (not as much as a balm), really glossy, and not sticky. They also smell kind of incredible, sort of fruity in a cherry kind of way (though if you're the kind of person who thinks that's a cough medicine smell you might not like it). I have a really strong gripe with the packaging, though: it's terrible. Not in the sense that I can't apply it evenly, the dow-foot applicator is totally fine and has a nice slant to it- the thing is it's just terribly weak, and sort of leaks. I dropped one of them on a wood floor (not tile or anything) and it just completely broke and I had to throw it away. And when I close the gloss, product always manages to squeeze out around where the cap meets the rest of tube, so that's frustrating. But I'm willing to put up with it for how incredible this is otherwise.
Perfect red is a blue-based red that I really like to put on top of more orangey reds for some reason. It's is a bit too sheer of a red for me to wear on its own (it's just impossible to get even) but as a topper for any other red lipstick, it just does something absolutely divine and makes it look incredibly sexy. It definitely transfers a lot, but still last quite a while; it also bleeds a lot without some sort of lip liner.
Natural is a pink-brown mauve shade, one of the best neutrals I've ever found for my skin tone. It is a bit on the cool side for my warm-toned skin, but not by much, so I'd probably say that it has a neutral undertone. It doesn't bleed like perfect red, but it only lasts for 2-3 hours as opposed to 6-ish.
