I am actually not very impressed with this product. I have worn it over top of lipstick and on its own and either way, it didn't last very long and actually dried my lips out quite a lot.
It's not sticky, which is a great thing as that's what I dislike about most lip glosses, but when it starts to wear off, it leaves a yucky residue on the lips.
I would love to find a way to prevent this though because the colours are just beautiful, very pigmented for a lip gloss and it smells sooo good.
I have got 2 of these lip gloss in the shades of Disco (light pink) and Shuffle (transparent), purchased about 2 years ago.
I really like using them at first - they were easy to apply and smooth although texture was a bit thick. This product has a very nice fruity smell to it - which was a bonus. It comes with an application tip which is connected to the lid when you twist open the tube.
However, after a couple of months the texture got very stick on the lips and my fingers get all sticky from opening the tube due to to product residue (make sure to wipe off any excessive product)
I have stopped using this product due to its sticky-ness but will occasionally use the Disco shade over pink lipstick application when necessary - Disco is a really lovely shade.
This product is also a bit pricey so not going on my repurchase list.
Tips: Use a lip brush to make the best use of this product; for a much even spread of lip gloss over the lips.
