Quick answer
Undertone is the underlying cast of your skin, separate from how light or deep your skin is. It helps narrow shades but should not override what looks right on your skin.
- 01
Start with shades close to your depth.
- 02
Compare warm, cool and neutral options side by side when possible.
- 03
Swatch along the jaw or another area that connects face and neck.
- 04
Let complexion products sit long enough to reveal oxidation.
- 05
Choose the shade that disappears most naturally rather than relying only on a label.
Using vein color as the only undertone test.
Assuming every brand uses warm, cool and neutral labels the same way.
Ignoring oxidation after application.
