Maybe the mineral makeup does not refract the light away from the wrinklesI agree with you- in part. I had a mineral makeup makeover in the salon I get facials at, and it did settle into the lines and add years.
However, on the rare occasions I do wear make up, I use Bare Essentials, and find it just gives me a little color, and evens out my completion. I don't find that brand settles into my frown lines- I really like it. I should say I do use a regular concealer, (a cheap one like Loreal) that is not a mineral makeup product.
