MAC Double-Gleam is a very warm-toned, very light gold with a metallic finish. It is a permanent blush that retails for $44.00 and contains 0.31 oz.
MAC Double-Gleam Extra Dimension Skinfinish ($33.00 for 0.31 oz.) is a light gold with warm, yellow undertones and a metallic sheen.
The Extra Dimension Skinfinish formula now features four, permanent shades--yay! (Finally!) According to MAC, it's a highlighter that "lasts up to ten hours" with "prismatic reflections." Double-Gleam was richly pigmented but could easily be sheered out or used with a less dense brush for a more moderate glow. The consistency was soft, smooth, and blendable, so it was easy to apply and work with on the face to highlight on cheekbones, down the bridge of the nose, and so forth. The shimmer in Double-Gleam seemed finer and smoother compared to past iterations in this formula, and I think it ended up being more forgiving on the skin overall. It has a much stronger sheen to it, so when worn at full coverage, it did emphasize my skin's natural texture slightly. The highlighter started to fade after eight hours on me.
