However, does mineral makeup give you all the sun protection you need? The experts say no.
It's better than using nothing, but it is recommended by specialists to use a regular cream sunscreen under their makeup and then use the mineral foundations as an extra boost.
Mineral Makeup: Not All Alike
Extra ingredients aside, it may seem as if all mineral makeup should be pretty much the same. But it was discovered that's far from the truth.
As there is no set regulation for what constitutes a "mineral” makeup, any product containing minerals as a primary ingredient can be marketed as such - even if it contains a whole lot of other "less natural" ingredients.
The battle lines between brands are drawn this way: "Mineral makeup formulas generally fall into two large camps - those that take care not to use synthetics (like paraben preservatives and other fillers) and stay true to the original intent of pure mineral makeup, and those that do add the fillers, colors, binders, preservatives, and other chemicals to their formulas.
Although you can discard at least some of these brands by reading the ingredient label, cautions not to let the term "all natural" or "all mineral formula" fool you.
That is because within the brands that claim "pure mineral" formulations, there is still another category breakdown - those that contain an arguably "natural" mineral known as bismuth oxycholoride, and those that do not.
A paralyzing agent that gives mineral makeup that "candlelight glow," bismuth oxychloride is a mineral, but it's not found in the earth. Bismuth appears to be a byproduct of copper and lead processing. Besides, Bismuth oxychloride is frequently used to fill or "bulk up" or bind products.
Bismuth oxychloride is thought-out as a skin irritant and can cause itching and rashes and in large amounts it can cause cystic acne as well – it's one of the ingredients you should try to avoid if you have acne or rosacea or sensitive skin.
Some products also contain very little, so it doesn't act like an irritant, but you won't know until you try it.
Mineral Makeup: Buyer Beware
One of the factors that makes mineral makeup so popular is the smooth, natural, long-lasting coverage - a feat that's some companies accomplish by pulverizing or "micronizing" their minerals into microscopic or even nanoparticle size.
Some researchers say this activity may come with a price.
Research shows that when some molecules are dramatically reduced in size to the level of a nanoparticle, they can have very different and very toxic properties than that same molecule would have in its conventional size.
Minerals like zinc and titanium are safe when applied to healthy skin but in a micronized nanoparticle form, there remains a concern, particularly when applied to damaged skin, or when inhaled.
Even when beauty comes from the earth, it's still a case of beauty buyer beware.
