My experience so far
I have purchased the following colors: Clear (in multiples and gifted some), Cherry, Watermelon, Midnight Sparkle, Sun Diego, Nude York, and Crimson.
Clear: will purchase again.
Cherry: is a bright red, I like it. Would like to see a darker red.
Watermelon: is like applying Pepto Bismol. To make things worse, it settles in every lip line. It's my fault; the color is exactly what it looks like online, but I was hopeful it would look good. I have tried it a few times, and it is the worst.
Midnight Sparkle: I am not crazy about glitter on my lips, but this color will stay in my collection. It is a step up from clear but not dramatic.
Nude York: It end up in the trash, not a good color for me.
Sun Diego: I do not like the color, but I keep it in my purse. I use it when I am out and about to finish it, but I will not repurchase.
Crimson: I prefer opaque, in the models it looks as described, "cool-toned deep rose", I am fair to Med, and it looks almost brown on me. The tube is darker than depicted on the website pictures. I use it a lot, I wish it were a deep rose, then I would have multiple tubes in different locations (purse, and my two jobs, backup tube).
I have considered Pink Nude, but it might just make me look like I don't have any lips; it looks so light in the picture. I bet it is still better than Watermelon :(
When it comes to the plumping effect, it is minimal even with daily use. When I reapply, I get no plumping effect, not even the optical illusion. What I like about the formula is the pillowy feeling.
