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.
Temper (Powder) is a light, rosy copper with moderate, warm undertones and flecks of glitter and sparkle throughout. This shade contained plastic (PET) glitter along with sparkle (the other shades in this formula did not contain plastic glitter). It had semi-sheer, buildable pigmentation but was best applied with a dampened brush due to the drier, firmer texture. The texture seemed to get more compacted over time rather than loosening or getting more forgiving, unfortunately.
It felt too-firmly pressed into the pan, which resulted in a product that was harder to pick up with a dry brush and seemed more reactive to natural oils on the fingertips, which is why a dampened brush seemed to be the best course of action. The surface hardened a bit after a few uses with fingertips in particular. It applied fairly evenly to bare skin, but it was more prone to fallout than other shades in the line, especially when I went to diffuse/blend out the edges. It lasted for eight hours but had light fallout over time.
