15. Mix an illuminating formula in with your foundation for a subtle glow. If you want a slightly dewy finish, apply a touch a pea-size drop of luminizer, on the back of your hand, followed by a quarter-size amount of foundation. Then, blend them together and apply it all over your face. If you only want certain parts of your complexion to glow, like your forehead, bridge of your nose, or cheekbones, only apply the combo over those areas.
16. If your skin tone slightly lightens or deepens with the seasons, alter your foundation shade with color-adjusting drops. Brands like The Body Shop and Cover Fx make tweaking your foundation foolproof, thanks to a dropper formula that helps you customize your shade.
17. Use a foundation shade with the right undertones for your skin. There are three classifications for undertones: warm, cool, and neutral. If you have warm undertones, your skin will appear peachy, yellow, or golden. If you have cool undertones, your skin will have a pink, red, or bluish cast to it. If your skin is neutral, then you have a mix of warm and cool tones. Figuring out which undertone you have is crucial because the right foundation undertone complements your skin, while the wrong one can make you look washed out or ashy.
Three quick ways to figure out whether you have warm, cool, or neutral undertones:
If you look better in gold jewelry, you have warm undertones; if you look better in silver, then you have cool undertones, and if you can wear both, you have neutral undertones.
If white clothing enhances your skin tone, you have warm undertones; if it washes you out, you have cool undertones.
Look at the veins in your wrist. If they're slightly greenish, then you have warm undertones; if they're blue or have a purple tinge to them, then you have cool undertones.
18. Use a makeup sponge to buff out your foundation. If you like applying your base with a brush, keep a stash of makeup sponges on hand to blend out any brush strokes for an I-woke-up-like-this finish that says, "No, I'm not wearing foundation (wink, wink)." If you're trying to get out of the house fast and don't have time to buff out the tiny strokes that brushes can leave behind, use a makeup sponge to apply your foundation.
19. Apply your foundation with downward strokes to avoid highlighting the peach fuzz on your face. Unless you shave your face with a facial razor, you most likely have peach fuzz on your cheeks that grows downward and isn't that noticeable. However, if you swipe your foundation on with upward strokes, you can bet that said peach fuzz will be highlighted and noticeable; swipe it on with downward strokes, and it remains less detectable.
20. If you touch up your eyeshadow before you go out, be sure to protect your foundation application. Whether you carefully tape a tissue to your face or use one of the handy Shadow Shields that I'm wearing here, it's a good idea to protect your base makeup so product fallout doesn't ruin your base. Otherwise, the general rule of thumb is to do your eye makeup first, and the put on your foundation for this very reason.
21. Finally, set it and forget it. To make your base foundation last all day (if it's not already long-lasting), run a fluffy makeup brush over a translucent powder and dust it over your T-zone. Or, lightly mist your face with a setting spray.
