I have a few tips, three to be exact. I used Bare Escentuals for many years and my skin (and age) has changed a great deal. With the birth of children- discoloration, with the march of time- redness, dullness etc, and of course wrinkles.
First, be sure not to use too much powder at a time. When I first used it I thought it was way to messy, but I was using too much powder at a time.
Second, the regular foundation will not cover my skin imperfections alone, use BISQUE to give your skin coverage. You can use it separately or make your own "custom" mix with foundation. I also add some bisque to mineral veil for my own pick me up.
Third, I have never been one to moisturize, especially with my oily T-zone and the onset of adult acne (at those times of the month). Most moisturizers etc make me breakout. But the Bare Escentuals BareVitamins can be used all over the face before applying the Bare Escentuals and it is great stuff! The label reads... skin rev-er upper and that is exactly what it is and the powder goes on so much better too.
Is your skin going through a crazy time and nothing seems to work? Just try Bare Escentuals for your self.
