Mineral makeup’s base is made up of crushed earth (minerals). Different types of minerals, such as titanium dioxide, zinc oxide and mica are crushed, blended to create different colors and sometimes mixed with other ingredients to be marketed as a number of products from foundation to lip gloss.
Mineral makeup has become the rage lately because of its positive effect on the skin. The zinc oxide in mineral makeup gives it an inherent broad spectrum SPF and works on all types of skin (rosacea, acne, sensitive, and post-laser treated skin). The particle size of most companies’ mineral makeup is larger than the pores, so it does not clog them; and the appearance of one using mineral makeup is natural and dewy and the coverage is exceptional, without looking like your face will wipe off on a napkin. Mineral makeup is also inert, which means it cannot spoil and therefore needs no preservative.
There is a green side to mineral makeup also; the flipside being there are ingredients that are best avoided when choosing a mineral makeup company.
Bismuth oxychloride, although a mineral itself, is known to irritate skin and stretches pores. There are many mineral makeup companies that use bismuth to increase profits by allowing the more expensive ingredients to go further.
Carmine, another irritant, comes from crushed beetles and is used in some mineral makeup for a red color.
Parabens should never be on mineral makeup’s ingredient list. If the minerals are pure, they don’t need preservatives. Therefore, parabens on the ingredient list is a red flag to let you know other ingredients have been added to the minerals to warrant preservatives.
