The entire Extra Dimension collection is a new formula from MAC. The Official blurb from MAC about the collection and the Skinfinishes in particular:
A liquid-powder highlighter with prismatic reflections that sculpts, highlights and models the face. The cool, creamy near-fluid formula creates a luminous, well-defined finish. Wears 10 hours.
Whisper of Gilt is described by MAC as "a light soft white with shimmery sheen". It definitely has a shimmery sheen, but I don't think I'd categorize it as a soft white. It's gold. A lovely gold. But gold.
I took 2 swatch photos below. Again, I'm having a hard time trying to figure out how to photograph highlighters. There is a heavy swatch on the right and a sheered out swatch on the left. I think the heavy swatch in the second photo is truer to color, but the sheered out swatch on the first swatch is truer.
The product goes on smooth. I was a little afraid that the first time I swatched it, that the pattern would be demolished, but it's surprisingly firm. I'm not buying the marketing bit about "cool, creamy near-fluid formula". It felt like a powder. A nice powder, but a powder nonetheless.
The internet tells me that this formula is probably if not an exact copy of the Estee Lauder powder gelee formula, then at the very least a really close copy. The MAC Extra Dimension skinfinishes have the bonus of being much larger and cheaper than the Estee Lauder powder gelees.
I think this is a beautiful highlighter. It is a lot more of a true gold than many of the highlighters I own, so I am happy to add it to my collection. The pan contains a TON of product and I seriously have no idea how I could even hit pan on this, much less use the entire thing. I am curious to see how the new formula holds up over time since I will definitely have this for a while.
The pan contains 9 grams of product and retails for $29.
