MAC Frosting is a neutral-toned, very light white with a matte finish. It is a permanent lipstick that retails for $20.00 and contains 0.1 oz.
MAC Frosting Lipstick ($17.00 for 0.10 oz.) is described as a "pure white [with a Matte finish]." It's a bright, stark white with a matte finish. It was pretty pigmented with nearly full coverage, but the consistency was a little drier and seemed chalky to me, so it didn't apply the best. Some of the color "cracked" as I smiled, and it could have gone on more evenly. For those who aren't looking for a full, opaque white to wear on its own, it might be more appealing as a mixing shade, as it will lighten anything you add to it. In my experience, it does seem to stretch other formulas and make them appear a little less smooth on. I was able to minimize this effect by applying some of the white first, then layering the darker shade on top with fingertips (the warmth helped maneuver everything into place). The shade lasted for four hours on its own and was lightly drying. Sephora In the Clouds (43) (P, $8.00) is more muted (95% similar). Kat Von D White Out (P, $19.00) is more muted (95% similar). Bite Beauty Blanc (DC, $24.00) is warmer (95% similar). Bite Beauty #058 (P, $18.00) is more muted (95% similar). NYX Coconut (P, $6.00) is glossier (95% similar). Anastasia Primary #1 (Vol. 1) (PiP, ) is more muted (95% similar). Dior Ultra Light (000) (P, $37.00) is darker, more muted, cooler (90% similar). Maybelline Wickedly White (DC, $7.49) is darker, less pigmented (95% similar). MAC City Slick (LE, $20.00) is darker, warmer (85% similar). See comparison swatches / view dupes side-by-side.
