These are a relatively new product from NYX and come in two shades: Nude (pictured above) and Deep Nude. However, the Nude is practically colorless and works like an invisible lip liner that can be applied more like a creamy lip pencil. It saves me time and sometimes even a look in the mirror on the go because it covers the whole lip surface with little effort and won't tug or pull.
After the first use, which seemed to get rid of the 'film' I am finding so many products have now, this turns into a creamy almost-balm that smooths onto your lips, takes out just a bit of color from them (which makes your lip product of choice more true to color) and primes.
This is a twist up product and retails for $7. I have tried it with a number of lipsticks: UD Revolution, Lancome, Rimmel, Maybelline, and NYX so far, and it extends the wear by at least two hours. It also helped make my tricky matte Lorac lipsticks easier to wear!
This swatch shows a large patch of slightly pinky, but otherwise colorless, primer. It melts into the skin and onto the lips and is very comfortable. This isn't a miracle product, but when I can turn 4 hour wear into 6-7 hour wear with minimized feathering/running, I am happy. Especially since it means no trying to line my lips, a skill which I do not have.
Do you have a favorite lip primer?
