If you have oily skin, you may not like the idea of slathering product on your face, but you shouldn't skip sun protection because you're afraid your skin will become slick and shiny. The cosmetics aisle often contains products that combine sunscreens with something else, such as moisturizer or foundation. While these products can save you time and money, remember that sunscreen is their secondary function. According to the American Academy of Dermatologists, "If you expect to be in the sun for longer than 10 to 15 minutes, dermatologists generally recommend applying sunscreen under your makeup -- even if the makeup has an SPF" [source: American Academy of Dermatologists].
Moisturizing, anti-aging, anti-acne and sun protection products can all work together without clogging your pores. The secret is to look for products that do more than one thing. Want to block damaging UV rays and bug bites? Choose a two-for-one sunblock with insect repellent blended into the formula. For anti-aging and sun protection benefits, look for topical products that combine sun protection with antioxidants such as vitamins C and E (beware, products containing alpha hydroxy acids may increase your chances of getting a sunburn).
Whether you choose a combination product or not, be sure you're applying your products in the correct order. To get the best results from all your skin care products, apply any topical acne medications or other skin treatments first to allow their ingredients to work, and then apply your daily moisturizer or moisturizer/sunscreen combination product.
