Love Bare Minerals! *LOL*
I've been using it--over 15 years, probably closer to 20 years! I am *mature* (aka "senior" per AARP!).

My skin is very fair (charter member of the burn, peel & freckle club) and a bit on the dry side these days.
I find the Bare Escentuals skin care products don't suit my skin very well. And I can't wear mascara--no matter who makes it!
But I do love the BM foundation, blush, highlighter and mineral veil. Depending on what my skin is doing, I use Fair or Fairly Light. Fair has more of a pink undertown and Fairly Light shades toward yellow/gold. It just depends on what my skin is doing each day. Sometimes I combine the two for just the right shade! *LOL* I also like Bisque as a concealer--I do not love my freckles! I have both the original and tinted Mineral Veil. Some days I use Mineral Veil as a primer--apply it lightly before the Bisque and foundation--as well as for finishing.
While I like the eye shadows, I rarely wear them these days. Between contacts (RGP--Rigid Gas Permeable) and my eyes being naturally dry these days, eye shadow doesn't stay on well.
I do like SmashBox eye liner.

Mine is the original putty type and it stays on fairly well. I introduced my BFF to Bare Minerals a few years ago (light olive complexion) and SmashBox eye liner (newer gel) just last year. She loves both!
