NOTICE: All products categorized under "Glitter" contain Polyethylene Terephthalate, also known as plastic or PET glitter, and it is typically cosmetic grade glitter. Inclusion of this ingredient sometimes carries a warning (in the US) that the product is "not intended for use in the immediate eye area." This ingredient has not been approved for usage on the eyes per the FDA. In recent years, some brands are including this product in their eyeshadows without any warning or callout and effectively marketing them as eyeshadows or including a symbol of an "eye" which suggests eye usage. Via CosIng for EU, PET glitter is permitted without any restrictions or limitations. For an in-depth look at whether cosmetic grade glitter is safe, please view this post.
MAC Just Chilling Shiny Pretty Shadow ($21.00 for 0.05 oz.) is a bright, medium silver with cool undertones and a sparkling, shiny finish. This shade had more shine than glitter compared to the other shades, though it was still plenty glittery on the lid. It had a very brightening effect when used on the inner tearduct or lash line. The consistency felt as smooth as you'd expect something packed with glitter would--not like silk but not gritty--and yielded nearly opaque pigmentation in a single layer.
I applied it to my lid using a pressing motion, which helped to minimize fallout while achieving even coverage. The eyeshadow stayed on well for eight hours before creasing in my fine lines a bit and had noticeable fallout over time, though there was a significant amount of sparkle/glitter still on my lid (and most of the color was present).
