These are newly released in the UK (only for now, I think) but for some reason I "had" to have them.
40: white base very light peach
42: white base light pink nude
43: no white base but slightly more orange and brown than 40
45: cooler pink than 42 with no white base: a nude so brown/pink
48: a darker nude, but with a slight red or plum undertone (depending on your lip shade I think) so not super brown thus more wearable.
These are mostly but not fully opaque. I like all but 40 which is too light on me for most looks. Same great Rimmel formula that I love but not everyone does. These will be making it the the US.
40, 42, 43, 45 and 48
