Hold the Bottle Up to Your Neck
“Bring the bottle up to your neck to try to match the color to your skin, as close as possible,” he says. Then, seek out the area of the drugstore that has the best lighting and mirrors.
In respect to this, how do I know my foundation shade?
Take a good look at the veins on your wrist under natural light for an easy way to determine your undertone. If your veins look green, it is likely you have warm undertones; if they are blue/purple, you have cool undertones. If they appear blue/green or match your skin colour, you most likely have neutral undertones.
When in doubt, always pick a shade that is slightly lighter than your complexion rather than darker. This can prevent your complexion from looking darker than the rest of your body. It is the safest way to go when unsure about two shades that may look too light or too dark.
