Makeup help?

Question

I'm buying a foundation and they're are options for cool, warm, and neutral undertones. How exactly do I know which undertone I have?

Answer 1

Here's more on how to determine your skin undertone:

Warm skin undertone:
1. Look at inner wrist - veins will appear green.
2. Gold jewelry is more flattering than silver jewelry.

Cool skin undertone:
1. Look at inner wrist - veins will appear blue.
2. Silver jewelry is more flattering.

Neutral undertone: either gold or silver complements the skin
