I have a two part question. First, a bit of background. I have recently discovered that all of the face powders in my collection that are marketed as "powder foundations" irritate my skin and aggravate my rosacea if I wear them daily. I switched back to an old favorite finishing powder (lighter weight than a powder foundation) and it does not have any of these effects. I wear it over a tinted sunscreen, so I really don't need the weight/coverage of a powder foundation anyway.
Question 1) Is there any ingredient typical of "powder foundations" that might dry or irritate my skin? Something to make it adhere to your skin perhaps? Or is it just that more product gets deposited in a powder foundation as opposed to a translucent powder?
Question 2) It appears my old favorite finishing powder has been discontinued. It is of the pigmented variety, as opposed to "translucent" white, which I like. It also gives a radiant effect, not totally flat/matte. I'm guessing because of the mica. Here are the ingredients. What should I look for in a replacement when I run out of this one? http://www.cosdna.com/eng/cosmetic_4b1b92427.html
