Not a plumper IMHO, but a great gloss, definitely!
I'm not one for plumping formulas (I think the hype is just that, really), but I fell in love with a color and had to try it out. Besides, PF happens to be one of my favorite d/s lines, and am continually impressed with their products, so I felt compelled to take a chance on this new plumping gloss.
Plump Potion in Spice Potion is a gorgeous warm-toned shade of highly metallic/light-reflective (that in and of itself can make your lips look bigger) bronzey rose.
The tube itself is pretty cool -- all Lucite, including the wand (which amazingly doesn't seem to pick up any gloss like other wands). It's also got a brush applicator, FYI.
The consistency of this gloss is very similar to Prestige's LightShine glosses (not sticky, but not greasy, either ... slick, like a silicone), so if you like those, you may very well like these. No sting (there's a VERY slight tingling sensation) or offensive taste (yay!), and I'm highly sensitive to the taste of glosses seeping into my mouth (ew).
Did I notice any plumping action? No, but again, I don't buy into that hype. The gloss is just a great, smooth formula that feels very comfortable on the lips.
I'm happy to say that PF didn't let me down with this new product, and I look forward to more new things to come from them!
