This product is nice when you want to look sultry. I like to let it sit on my bare lips, giving them an even plumper, deeper look.
It's a bit sticky, and needs to be reapplied fairly often. It's also rather pricey but I don't see it as a daily item. It's more for going out for me. It also tends to dry out my lips.
On the flip side, it actually coats them so well that I feel protected from harsh, windy Midwestern winters! It's also lovely over a light, matte lipstick. It gives a gloss and plump, if you would rather merely have a tingly-pout feel instead of a blushy-red colour along with it. Many ways to use it! I really like it and if I run out I will probably buy it again as the tingle is sort of addictive. Be aware of course that kissing will transfer the peppery feel and your other half might be in for a surprise.
Overall it's not terribly plumping or noticeable, but it does inject a dose of natural, flushed colour and a slight tingly fullness.
