I've tried many different concealers. Most of the time they make your under eye area look worse and highlight any fine lines. When I started using Pur Minerals 2 years ago, I used a lighter shade of the 4 in 1 pressed mineral foundation until I tried the Pur Minerals Color Correcting foundation Primer in Peach. It works great!!
Put a small bead of the Primer on the back of your hand. Take a small brush and dip into the Primer and draw small circles to distribute the Primer in the brush hairs. Dust your under eye area lightly and let dry. I also dust my eye lids with any left over Primer. By the time I have the 4 in 1 pressed mineral foundation applied, the primer is dry. I then dust a small amount of mineral foundation over the primer. My dark circles are gone for the rest of the day!

I use the utility mineral makeup brush with my 4 in 1, also try using the intensive eye treatment to help dimish the dark circles all together. It has worked wonders for me.

I use concealer, a lighter shade than the foundatio.

The Revitalizing Cleanser is the best one to use for your face. It will clean,even take off eye makeup, without drying your skin.

I find the Mineral Wash very harsh even for my hands. I would therefore suggest using Facial Cleanser.

I have combination skin also & I would definitely recommend the Revitalizing Facial Cleanser over the other one. I've tried both & I found the Mineral Wash to be just a little too drying for my combo skin. I use the Revitalizing Facial Cleanser twice a day without getting "stripped". Hope this helps.

Yes, everything is non-comedogenic.

i beleive it is it is pure!

It's entirely up to you. I love in a dry climate are and I sometimes later on night cream under my sunscreen because my skin gets soo dry! Just don't forget the sunscreen.
