MAC Acai is a slightly cool-toned, medium berry with a semi-matte finish. It is a limited edition lipstick that retails for $20.00 and contains 0.1 oz.
MAC Acai Lipstick ($17.50 for 0.10 oz.) is described as a "vivid deep violet [with a Matte finish]." It's a lightly brightened, medium-dark fuchsia-berry with cool undertones and a semi-matte finish. The texture was a little drier, though it didn't drag too much when applied, but it seemed to emphasize any dryness/natural texture on the lips as it wasn't as thick or as velvety in feel as some of MAC's recent matte finishes have felt. It had mostly opaque color coverage that wore well for six hours but was fairly drying. Tom Ford Beauty Xavier (LE, $32.00) is lighter. MAC Fashion Revival (LE, $16.00) is darker. NARS Fanny (P, $32.00) is lighter. MAC Splurge (LE, $22.00) is lighter, glossier. Marc Jacobs Beauty Cabaret (146) (LE, $30.00) is glossier. Estee Lauder Insolent Plum (P, $30.00) is glossier.
