Diffuser brush
I thought I'd like this brush a lot more than I do. I gives a nice finish to foundation but feels more work than a shaving style brush

Use gentle swirling motions to buff Concealer/Foundation into the skin. Take time when applying to ensure an even, smooth finish. We recommend a soft pressure to work the product into the skin.
