[3]Cerebrosides (cells from the nervous systems of cattle or swine) were once used in some high-end skin-care products to increase moisture retention and to create a smooth skin surface, [4] however the BSE controversy has put an end to this practice.
The chain silicate structure of the pyroxenes offers much flexibility in the incorporation of various cations and the names of the pyroxene minerals are primarily defined by their chemical composition. Pyroxene minerals are named according to the chemical species occupying the X (or M2) site, the Y (or M1) site, and the tetrahedral T site.
Although harmless products were used, such as berries, and beetroot, many cosmetic products available at this time were still chemically dubious and even poisonous.

Diopside is a monoclinic pyroxene mineral with composition MgCaSi 2 O 6. It forms complete solid solution series with hedenbergite (FeCaSi 2 O 6) and augite, and partial solid solutions with orthopyroxene and pigeonite. It forms variably colored, but typically dull green crystals in the monoclinic prismatic class.
