this powder is really nice if you're not looking for much coverage, and is good for people with discoloration in the skin as it evens out your complexion. however, if you're looking for anything to cover acne or breakout areas, this probably won't do you much good. it's really good for a quick everyday touch up, and feels nice on the skin.
The formula seems nice enough, although I found it difficult to apply evenly over areas on my face that have texture (large pores and acne scars) even when used with different types of primers. Light/medium was shade recommended on the NbN website but it was far too yellow for my medium neutral skintone (EL 3N1). I didn't persevere with colour matching as I found my shade in a different brand mineral powder foundation that I'm happy with.
I was a super fan of the Nude By Nature mineral powder, that is until I stumbled on this product! I have not used any other mineral powder since. It is a great product. The dispensation design is ingenious, it is more hygienic, much less messy and not as wasteful. You have to 'grind' the powder out and then apply. With a good brush this things does wonders. You can layer it if you want more coverage as well.
