Besides from Diamonds, Glitter is a girls best friend. That is, if you know who to work it into your makeup looks. There are many different cosmetic lines that have safe to use glitter such as Mac,Urban Decay, Sugarpill ect. Only glitter that is sold as a cosmetic or is sold in the cosmetic section is in my opinion the only glitter you can be pretty aware of the safety and purpose of the product, but if you buy regular craft glitter from your art supply store .. It is only in tended for craft purposes only! Not for face nor eye contact, because of the consistency and the chemicals/ingredients found in the product. Here is a scenario, What happens if you get a piece of thick glitter,or even small little flake into your eye and it starts to itch and you notice your eye gets bloodshot red? What happens is that using the wrong type of glitter can have harsh features that can irritate, and scratch your eye, or even can cause permanent loss of sight! So just be cautious on how and what kind of glitter you use so you are safe. :)
