MAC Saint Germain
Maybelline Colorsensational Pink Pop
Comparison swatches: (Left to Right- Saint Germain, Pink Pop)
Saint Germain is more opaque and has a shinier finish to it. It's lighter/brighter than Pink Pop. It tends to dry my lips out more than the Maybelline Colorsensational Lipstick.
Pink Pop leans more towards a fuchsia color and is slightly darker than Saint Germain. It seems to be less "milky" looking. Pink Pop doesn't last as long but it also doesn't irritate or dry out my lips.
Saint Germain and Pink Pop are light, blue-toned pinks; I personally think both are gorgeous! I enjoy these lipsticks a lot (especially when my skin looks sun-kissed but also year-round).
I would't call Pink Pop an exact dupe for Saint Germain. They're similar but certainly not twins :)
