Review: Too Faced Lip Injection Extreme

I quite like my lips as they are with a touch of Mac Oak lipliner and that's usually my daily lip. However I also like to accentuate them when I feel like it, I have tried the Too Faced lip injection in Techno Buff which works great but I wanted to see what "Extreme" could do.
Please note: my lips have some Bobbi Brown moisture rich foundation residue on them.

The Verdict: I love it, it's a great alternative if you want your lips to be fuller! It goes on quite smooth and is not too sticky, within 2 minutes it starts to TINGLE and sting! You can actually feel it working and watch it plump up, it feels like peppermint and like you have just had your lips done with silicone. It basically inflames your lips to its full potential. You can see a significant difference in my upper lip where the cupids bow is, also my bottom lip looks more rounded.

The product itself is a clear gloss with tiny baby blue and pink reflect and has a brush tip applicator.

It lasts for a few hours, if I was wearing it on a night out I like to apply it twice as the tingling sensation fades and I like to feel the tingle. :) This would be lovely applied on top of a perfect nude lipstick.

I wouldn't advise you try this if your lips are sensitive, It's best to test it in store first - I have read about some horror stories with people having an allergic reaction to this product so use with caution.

Have you tried this before? What do you think about it?
