MAC Let It Glow is a moderately cool-toned, very light silver with a sparkle finish. It is a limited edition highlighter that retails for $37.00 and contains 0.31 oz.
MAC Let It Glow Extra Dimension Skinfinish ($37.00 for 0.31 oz.) is a silvery-white with cooler undertones and a sparkling, luminous finish. It had larger flecks of sparkle in it compared to most of the Extra Dimension Skinfinishes I've tried over the years, which may come as a surprise to long-time fans. The texture was fairly smooth but had a drier feel to it than past shades in the formula, though by no means actually that dry/dusty--just not nearly as smooth and firm.
It had semi-opaque color payoff that applied evenly to bare skin and had good dispersion of shimmer/sparkle. The base seemed more translucent to me, so the coverage came more in the form of shimmer/sparkle to my eye. The finish was shinier, but it did not emphasize my skin's natural texture. It wore nicely for eight and a half hours before fading a bit, and the shimmer/sparkle didn't seem to migrate noticeably.
