A popular question I hear all the time is, what do you think about mineral makeup? To answer this, you have to ask yourself, what is mineral makeup? Minerals like titanium dioxide, mica, and iron oxides have been in makeup for years, and is nothing new to the cosmetic industry. So many consumers try to be good consumers by buying "natural", "mineral", "healthy" products. But, beware... just because it says "mineral" on it, does it make it a good product?
Strolling through CVS the other day, I picked up various mineral makeup foundations and most of them had the same crappy ingredients that have been in makeup for years. Let's do point out that "mineral oil" is HORRIBLE for your skin and clogs pores. If this is the first (or last) ingredient listed in your foundation, throw it away. And why are dyes and fragrance in a mineral and all natural foundation? "All natural ingredients" does not mean that ALL of the ingredients are natural.
So many cosmetic companies have hopped on the mineral bandwagon to sell you their makeup. However, I don't think that all mineral makeup's are bad. Your foundation should be fragrance free (a skin irritant), dye free (you should have no yellow # whatever, etc.), and mineral oil free.
There are several great mineral lines out there, but always take a few moments to see what the ingredients are. Also, bismuth, a popular mineral (it's what gives powders that "glow") is a great ingredient when used sparingly, or in the right places. If it's your first or second ingredient, and you can't figure out why you are always shiny, this is probably why. I prefer the foundation to be bismuth free, and to use the more glowy powders for highlighting.
I don't use alot of mineral makeups because they are in powder form. These are great if you just want a quick light dusting, or if you are 16 with perfect skin. My personal preference is liquid, and I can always get a fresher and more youthful look with them.
