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.
ColourPop IYKYK Pressed Powder Shadow ($4.50 for 0.04 oz.) contains a mix of small-sized glitter particles that seemed to read mostly pink but also had flashes of green, blue, and lavender throughout. It appeared to shift green-ish when the light reflected off of it. The texture was lightly emollient to the touch, but it was textured as it did contain quite a bit of glittery bits.
It applied best with a fingertip but also worked with a flat, synthetic brush, as the majority of the product spread evenly over my skin. It does contain plastic glitter, and it is listed as not intended for use on the eye area. On me, the majority of the product applied without migrating/falling out and there was light movement and fallout over an eight-hour period.
