This is really true. Also, what I’ve found is that sometimes minerals which are ok for parts of your skin negatively impact other parts- like I once used a concealer with titanium in it, and it irritated the skin around my eyes really badly, but it didn’t irritate the skin on my cheeks.

I try to stick with the fewest ingredients possible, and not change products too often- that seems to work best for my skin.

Compared with the stuff found in other cosmetics I’m willing to take my chances with the minerals. The parabens scare me.
I found this site somewhat helpful: www.mineral-cosmetic.com when it comes to a brief explaination of what you’re likely to find in most of this stuff.
And this guide on eBay also very useful.

Both myself and my clients have experienced the wonderful benefits of mineral makeup. So many times has conventional makeup been the cause of acne for my clients, it is amazing to see as soon as the change is made to mineral, the skin can breath, it is supported not stressed, the change happens. It was the best move I made to switch over from conventional makeup. We use Jane Iredale Mineral Makeup, for all skins and skin types is so natural looking yet covers unbelievably well for all skins like rosacea, acne and pigmented skins.
