As per Bustle, the worst thing that you can do when it comes to glittery makeup products, such as lip gloss, is to use craft glitter. Craft glitter isn't cut in the same way that cosmetic glitter is, and it uses a different form of dye — neither the cut or coloring of craft glitter is safe for skin. That's why, if you are going to use loose glitter — such as to add to lip gloss for a glitter finish — it needs to be cosmetic glitter.
As per Eve Dawes, it's best to avoid "plastic or natural MICA glitters that don't break down, look for polyethylene or synthetic fluorphlogopite (aka synthetic mica)" instead. According to Glamour and Gains, these kinds of "microplastics can be found throughout the world's oceans, from the surface to the deep sea floor" and can impact the entire marine bio system. You can still create amazingly glittery lips using eco, plastic-free glitter that doesn't negatively impact the environment. Plus, using the right glitter will protect your overall health and wellness in the long run.
