Cosmetics come in a wide variety of shapes, sizes, and colors. They are used for many things and their composition varies widely based on the intended purpose. Additionally, their ingredients range from acids, to bases, and even some perishables items. This large amount of ingredients means that government regulation of packaging is very important. It oversees the safe design, production, and distribution of cosmetic products and their packaging. Unfortunately, it also makes cosmetics very hard to regulate, so governments have implemented large, overarching policies to blanket the industry with a set of guidelines. Most governments only review products on a case by case basis.
