I have found (thanks to my friend Eva) the most amazing lip product ever!! It's the Soft Matte Lip Cream by Nyx. She introduced it to me one day before a math class and I was just so impressed by the look of it on her lips. It gives a matte finish that is absolutely stunning, think Kylie Jenner's lips. It's also the easiest thing to apply, and to take off when you've done mistakes, since the texture is very similar to a mousse.
One thing I love about this brand is that all the colors are represented by a city. For now I only have the "Milan", a mid-tone blue-toned pink, and Stockholm, a mid-tone beige pink, but I'm hoping my collection will somehow grow over the months.
Lips were definitely a "thing" at the end of 2014 but I'm sure they'll still be major statement accessory in 2015, that's why I think that this product is going to be revolutionary (for me at least). The color is really pigmented but I love it! Oh and I'm eyeing the shade "Copenhagen" (a matte rich plum), but haven't seen it anywhere yet.
