Tips: 

Although primer is typically used as a base on which to apply foundation, you may wear primer on its own when you don't want a fully made-up look. Primer smooths your pores and minimizes the appearance of fine lines. 

Try different types of primers before purchasing one. They are sold in a wide variety of textures, and some are colored. Ask for samples at beauty counters and boutiques to help determine which options are more attractive for your skin.

Always use primer before spraying on airbrush makeup, to ensure an even application and smooth look.
