Summarize this article in one sentence.
Cosmetics that do not clog pores are called noncomedogenic or non-acnegenic. The first ingredient in your makeup should be water. . Opt for mineral-based cosmetics, which will absorb excess oil and hide redness without irritating your skin. Noncomedogenic makeup does not interfere with acne medication. Use oil-free primer to keep your makeup in place. It can be especially difficult to keep concealer on an inflamed zit, but a dab of primer does the trick. Lightweight primers are less likely to irritate acne and are easier on oily skin.  Use a primer with SPF for protection from the sun, especially if you have scarring or hyperpigmentation. Sun exposure can slow the healing process. Apply the primer all over your face to help your makeup go on evenly and last longer. A mineral-powder foundation is less likely to clog your pores than a liquid foundation, though it will provide less coverage.  Opt for mattifying products: they absorb excess oil, and a matte finish conceals bumpiness.  Avoid shimmery finish, which will draw attention to bumps. Foundations that are designed to last all day are more likely to clog your pores, causing further acne. If you're interested in light coverage, an oil-free tinted moisturizer can work great on acne-prone skin. It also won't clog pores! Concealer that is too light or dark will highlight your trouble spots, rather than hiding them. Mix two shades of concealer if you cannot find one that matches your skin.  Keep in mind that oily skin can oxidize the concealer, which will make it look darker. You can avoid this by choosing a concealer that is 1/2 a shade lighter than your skin color. Setting powder can benefit oily skin, but can exacerbate dryness in other skin. If you choose to use it, find a light setting powder that is less likely to trap oils under your skin.

Summary:
Acquire oil-free makeup. Pick the right primer for your skin. Consider a powder foundation. Find or make a concealer that matches your skin tone. Consider using a setting powder.
