When I wear a dark lip I am very conscious of it bleeding or smudging so I do have to wear a lip liner to help out with that problem. I picked up Sleeks 'Eau la la liner' in the shade Venom, which from the packaging looked like it would be a purple berry shade, when in fact when swatched & applied to the lip it is a more red toned dark cherry shade.
I was a little disappointed considering it wasn't the color I was expecting, but none the less it still worked well lining my berry lipsticks & more red toned ones to.
The longevity of the liner is seriously amazing, it will fade slightly when I'm eating or drinking but other than that it is really budge proof. So with that being said I have actually opted for using this shade as a all over lip color more often than my actual dark lipies. As I feel safe knowing that it will stay put & won't smudge across my lips. After about an hour or so my lips can start to feel a bit dry from the liner, but I simply apply some lip balm & problem solved.
When I was doing some research into this lip liner I found out that sleek promote the 'eau la la liner' as a multipurpose liner to be used on both the lips and eyes. For hygiene reasons I don't personally like this idea, but for the purpose of testing out the liner I applied it to my eyes & needless to say the red liner made me look like a vampire haha, so great for Halloween but not an everyday look that I would go for.Sleeks 'eau la la liner' is available in 20 different shades, so plenty to choose from. Also another HUGE selling point for me is that this product is not tested on animals.
