I've been using BareMinerals for 15+ years.
At home, where the temperature can reach 110+ degrees, I use a moisturizer, followed by SPF 30 sunscreen, followed by Mineral Veil, followed by foundation (fair or light or combination there of), followed by Mineral Veil. The Mineral Veil acts as a light primer--I can't use regular primers--I break out like mad!

Contrary to popular belief, our summers are quite humid for 6 to 8 weeks--in addition to the horrendous heat! We just had a break for a few days, but the mercury is climbing again...!
While at WDW, I don't wear make-up to the parks in the heat and humidity, just moisturizer, sunscreen, tinted moisturizer (Serious Skin Care most recently, but also use other brands) and more sunscreen! In the evenings--or when I need to look a bit more polished, I use the same products as at home.
As a point of reference, I'm a charter member of the burn, peel and freckle club.

Translated: very fair!
