I was worried that applying foundation or primer with my hands would result in uneven application and dirty hands, so I decided to try using a brush. I looked at a few different products in the store and ended up buying this Lunasol product, which seemed to be dense yet soft. I usually get by with a high-coverage primer, so it's important that the primer is applied neatly. By using this product, I can apply it quickly, neatly, and maintain a glossy finish. When applying it to my face with my fingers, I apply a small amount in some places, and then I just spread it with this brush without applying too much pressure, and the finish is so much better than when I used my fingers!
