Make Up For Ever 1 Frozen Silver is a slightly cool-toned, very light silver with a metallic finish. It is a permanent highlighter that retails for $21.00 and contains 0.03 oz.
Make Up For Ever 1 Frozen Silver Star Lit Powder ($21.00 for 0.02 oz.) is a light, bright silver with cooler undertones and a frosted sheen. I'm not entirely sure why they went with the "Frozen" label here, as all of the other "Frozen" shades were duochromes but this one wasn't. It does, though, brighten well as it was lighter and brighter in hue. It had semi-sheer coverage applied dry, which was buildable to semi-opaque coverage, and then opaque coverage when applied with a dampened brush (just using water). The consistency was soft, blendable, and easy to work with on the skin and did not emphasize my skin's natural texture. This shade wore well for eight hours on me.
The Star Lit Powders can be used to "highlight eyes, lips and cheeks" with an "ultra-fine loose powder" that can be used "wet or dry to customize coverage intensity and luminosity." While checking the weight on these, I noticed that the weight differs from shade to shade; this one had a mere 0.02 oz. while others ranged from 0.03 oz. to 0.09 oz. I also noticed that it appears the brand identifies what area you can use a shade on by listing an icon on the back of the jar in the shape of a pair of lips, an eyeball, and then a face (presumably for cheeks).
