The key difference between mineral makeup and other department store makeup is what’s missing from the ingredient list. So stuff like parabens, mineral oil, chemical dyes, fragrance etc. Typically, dermatologists recommend mineral makeup primarily for this reason.
A good mineral makeup should leave your skin feeling a lot less weighed down, and if you have acne prone skin, no mineral oil should mean less breakouts. As a matter of fact, some people who could never wear makeup, having discovered mineral makeup are wearing it for the first time. Now that’s amazing!
Keep in mind that there must be some sort of preservative for a mineral makeup product to remain pure without bacteria forming. If you want to know exactly which one is used, just ask.
