To fake bigger, fuller lips you really only need one product (I kid you not!). All you need is a nude lipliner. One that matches your lips perfectly, for me that’s SubCulture by MAC.
Start by lining the outside of your lips, but instead of going right on the edge, go just outside, where your natural skin colour starts.
Next fill in the lips with the same liner pencil, this will make the whole lip area even and realistic. Want to go bigger? Just outline again!
If you have a smaller top lip than out line just it to even them out or bigger bottom? Vice versa.
