It takes a few mins to work. You will feel a tingling sensation. My lips did plump up slightly but I would rather spend money on a product based on colour and shine.

More of a painful experience than anything! It started as a tingling sensation and turned into a vibrating feeling that was not plesant. And I didn't see any change in lip enhancement. Certianly not worth the money!

Slight tingling sensation when you put it on. Looks good with a nice shine. Can probably just use alone without lipstick.

Your lips tingle as soon as you put it on so you know it's effective. And, my upper lips feel plumper but not sure if it really is

This product left a really nice shine on my lips but the stinging sensation I experienced from it left me dissapointed. It almost felt like I was having an allergic reaction to the gloss. It did plump my lower lip slightly but sadly, I won't be purchasing this product anytime in the future.

It tingled a lot to the point of hurting and i didnt really see any plumping.

Comes in a decent size for the price ($22). Adorable packing with the silver and pink color scheme! The tingly feeling from the plumping effect works instantly when applied to the lips. However it has more of a sting than most other lip plumpin effects. I have full lips naturally but I noticed a slight plumpin on my bottom lip!

Has an interesting sensation... Very effective... Able to to see a difference on my lips.

Too tingling for my lips and burning feelings. Really not getting over to it and it's been 10 minutes.

Feels like a buzzing over and over. My lips are plumping but,my lower lip,is protruding out a,little too much. The buzzing is starting to make my lips going numb, and I believe women more look on the colors for lip glosses than the cure for thin lips.
