MAC Superb is a moderately warm-toned, medium-dark copper with a metallic finish. It is a permanent highlighter that retails for $44.00 and contains 0.31 oz.
MAC Superb Extra Dimension Skinfinish ($33.00 for 0.31 oz.) is a muted, medium-dark rosy brown with warm undertones and a metallic sheen. The color seemed to be slightly rosier than the last version of this I had (from a limited edition release). It had excellent color coverage that applied evenly to bare skin. The texture was smooth to the touch without being dry or dusty in the pan. It was easy to apply at full coverage and then diffuse the color or to use a lighter touch for less intense shine. The finish, while nearly metallic, did not accentuate the texture of my skin. This shade wore well for nine hours on me.
The Extra Dimension Skinfinish formula is supposed to give "the perfect glow to the skin" with a "creamy powder formula" that wears for "10 hours." It's a powder highlighter that I'd describe as a moderate to intense highlighter, and they come in varying hues with some that might work as highlighting blushes/bronzers are on some skin tones and true highlighters on other skin tones. In general, the formula is very pigmented, blendable, and wears around eight to nine hours on me.
