- Primers: With brands like Laura Mercier and Smashbox leading the way, more and more women are understanding the need for these premakeup products, says Johnson. Not only do they prevent caking and creasing, but they help your makeup stay put. (And that's why practically every beauty brand carries one in its line.)
- A foundation brush: "A foundation brush really makes the difference between putting on foundation and having it look like skin, and putting on foundation and having it sit on top of your face like makeup," Johnson explains. Shop foundation brushes here.
- A concealer brush: "Whether you use a concealer brush to pad on opaque concealer over brown spots or over blemishes, it still gives you more accuracy and helps you to get all the angles around what you're doing," she advises.
