Mmmm, daydreaming of lippies, now that I can do half asleep! Thank you for asking, I love how you value customer input...
I have 2 HG lip products. The first would be creamy and plush, kind of like the black label lippies are, but a bit denser (like lipstick). In a hot fuchsia with blue, and a creamy pale peachy golden color. I need them more opaque and dense so they will override my natural lip color. In a tube, like the black labels. Little bit of shimmer is fine, but mostly rich, matte, slight shine.
The second would be in the squeeze tube like Feyith mentioned, though I love the wand glosses you make too. The texture of them is great too, I love that my hair doesn't get glued to my lips when I wear them! Bright orange, purple, or fuchsia, they can be see through or shimmery. Sheer colors to wear alone, or layered over other products. I'm thinking like the L'Oreal Juicy glosses
http://www.amazon.com/LOreal-Colour-Jui ... B000A6PJLO These would be my summer option because I'm prone to leaving things in the car, so wear glosses almost exclusively in the summer thanks to the southern heat. I'd also be cool with the colors being a stain, with a clear gloss to use over them.
Lasting to me means a few hours at best, I don't mind reapplying as a trade off to avoid dryness. A bit of a stain quality so that it doesn't totally disappear in darker shades would be nice. There's nothing worse than drinking a glass of water and then realizing most of the color is on your glass except for a dark outline ala the "dark lip liner" trend a few years ago.
I prefer slightly sweet, but can't be any sort of artificial sweetener. I like vanilla or peppermint for flavor in the lipsticks, or a fruity one like coconut or cherry in the glosses. My preference being for gluten free flavorings, of course...
Plumping is fine. I've used ones that sting a bit and they were okay, I'd prefer something gentler that plumps because it's hydrating the lips. The additive you mention sounds just fine. If it's really good for the lips though, perhaps the emphasis should be made that it's more an "antioxidant" additive than a "plumping" additive, since it seems some get hung up on plumpers that sting and this isn't one of those?
