What’s your favorite brush and why? I can’t live without my flat top foundation brush. It’s the best brush for achieving an airbrushed finish with a cream or liquid foundation. It also has the most bristles of any brush at over 10,000 so requires half the amount of foundation you’d normally use. My favorite of the flat top brushes is the @itcosmetics one pictured here (left). It can also be used with foundation powder for a fuller coverage. Photo by Diane Chappell @chappellstudiosportraits
