8. You also need to think about the color of your neck when searching for your perfect foundation shade. If your neck is much lighter than your face and chest (it might happen when your chin shades it), split the difference and go for a foundation in between the color of your face and neck. This way, everything looks like it blends together seamlessly. And remember, your face stops at your chest, especially if you're wearing a strappy, strapless, or low-cut top. The last thing you want is for your face and neck to look even and your décolletage to be red and splotchy.
9. Don't forget to apply foundation over your eyelids to reduce redness. Doing so instantly conceals any redness from superficial capillaries that are visible through thinner eyelid skin. Plus, it makes you look like you actually slept eight hours; skip covering them up and you'll look like you were out all night.
10. If you don't have a window (or good natural light) in your bathroom, smooth foundation on at your sink, and then check it in natural light. This helps ensure you walk out of the house with the right foundation shade, as well as zero telltale signs (like unblended areas) that you just fully made up your face.
11. If you tend to break out, always use an oil-free foundation; if you have drier skin that doesn't break out, try an oil-based formula. While it's good to hydrate acne-prone skin, dermatologists will tell you that using oil-based products isn't the best way to do it, since the heavier formula can clog your pores. That's why opting for water-based foundations are better for sensitive and oily skin types, while drier skin types — and those who don't often break out — can handle the heavier formula.
To figure out whether a foundation is water- or oil-based, look to the ingredients list. If it's water-based, it will list water as the first ingredient and most likely be labeled oil-free. If it's oil-based, an oil — like argan oil, for example — will be included in the list of ingredients.
12. If you find yourself without concealer, place a small dot of liquid foundation on the area, wait a few minutes for the formula to set, and then lightly blend it out.The trick is to wait until the foundation dries and thickens a bit (it will eventually reach the consistency of concealer) before trying to blend it. If you blend it too soon, the foundation will be sheer and rub off, leaving you with very little coverage.
13. Contour your face with foundation. Don't have a separate contouring palette handy? Use a foundation that's one shade darker to create depth, and one that's one shade lighter to highlight the center of your face and underneath your cheekbones.
14. If you want to turn your matte finish into a dewy one, apply a drop or two of a facial oil onto a sponge, then smooth on your foundation.
