Maybe you started the day with a fresh glow. Maybe you washed off all those excess oils and left your skin dry -- maybe dewy, at most. But by the end of the day, your skin has churned out enough oils to make your face shinier than a holiday tree ornament. Don't let oily skin ruin your day. All you need is a makeup that combats shine for a breezy complexion that will last all day.Go naturalYou don't have to forgo makeup for a natural finish; just dab on some oil-free mineral makeup. This is a non-comedogenic option -- meaning it won't clog your pores -- equals less oil build-up. To really combat oils, make sure it's a matte makeup, which absorbs oils as your skin produces them all day, according to "Marie Claire" website.Skip greasy formulasLiquid makeup gives optimal coverage -- a bonus if you want to cover the occasional zit or red patch. But sometimes a matte liquid makeup isn't enough to keep shine completely at bay all day. In these cases, finishing your cosmetic routine with a dash of powder can help keep your makeup in place and eliminate shine. Plus, powder often comes in compacts that will fit into your purse for daytime touch-ups.Don't sweat off Your makeupAs the day wears on, your skin produces oils that can leak through makeup -- and that leaves you with makeup that looks caked on or nonexistent. To prevent this, find makeup that contains salicylic acid. It's in many products that fight acne, because it keeps excess oils from building up in your pores. Apply makeup with this special ingredient to keep your face from becoming a shiny object as the day progresses.A few extra tipsOil-free, non-comedogenic formulas are best for oily skin, whether you're using foundation, cover-up, blush or bronzer. Go for matte options whenever possible, such as a light matte bronzer to dust your cheeks with color; they'll attack greasy shine. When you're looking for a new shade of foundation -- or anything else -- keep in mind that your skin's oils can darken your makeup, so opt for a shade lighter than you think you need.
