At the moment ( and even all the time ) : a Mineralize one. I often wear Rosy Outlook but I love, love my Mineralize blushes.
Petal Power, Azalea in the afternoon, Just a Wisp, Modest blush and Sweet Sentiment; I have only 5 Mineralize blushes, they are my HG blushes esp when my skin is uneven and when I am tired, it gives such a healthy glow.
I have other HG blushes my Chanel ones. Discrétion, Pink Explosion, Frivole, Rose Initial or Narcisse, whatever but a JC blush !
And my Benefit ones esp. Dallas, Hervana, Bella Bamba ( discontinued here WHY did they discontinue such a great blush )
If I had to choose one HG blush, well that's impossible lol
