Pimples are caused by bacteria, excess oil and shedding of dead skin. Most people at one point or another have had a pimple or two show up on their face at the most inconvenient times. When you have to be somewhere important, such as a party or a business function, that pesky pimple is there for everyone to see. If you currently have a noticeable pimple on the center of your face, such as on your nose, you can make it less visible with a little makeup.

Rub oil-free moisturizer and foundation primer on your face. Moisturizer helps your makeup go on more evenly, while a foundation primer keeps it from sliding off. Wait a couple minutes for the moisturizer and foundation primer to absorb into your skin.

Dip a flat-top brush in a quarter-size amount of liquid foundation. Apply the foundation all over your face. Choose a foundation that is neither too light nor too dark for your skin tone. Allow the foundation to dry.

Dip a concealer brush into cream concealer. Pat the concealer directly on the pimple and blend into the skin. Don't apply too much concealer to avoid a "caked-on" appearance.

Apply powder to your pimple and then the rest of your face with a large powder brush to set the foundation and concealer. Use the powder sparingly, and sweep the brush across your face in long strokes.
