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.
Kaleidoscope has a transparent base chocked full of lighter blue and more cyan blue, smaller-particle glitter along with some more iridescent flecks of glitter. It contains plastic (PET) glitter and is not approved for usage around the eye area. The texture was more emollient and malleable, which enabled better dispersion on the skin, but it wasn't the most even application of glitter compared to other shades in the range. There was some migration apparent after eight hours of wear (on cheeks).
