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.
Brew Potion is a darker, golden bronze with warm undertones and a glittering finish. This shade was listed as "not intended" for the immediate eye area as it did contain plastic (PET) glitter particles. It had more of a base color, so it was quite pigmented in a single layer and had a more emollient consistency--this did help more of the particles actually adhere to skin and minimized the chance of fallout. I'm not comfortable wearing it on my eye area myself, so I tested it as a highlighter, and there were some stray particles after eight hours of wear.
