Test shades on your jawline, not your hand or wrist
Check the shade in natural daylight
Choose a shade that disappears into your skin
Compare at least three nearby shades
Match both face and neck for consistency
Consider how the foundation oxidizes after application
Test the foundation and wait a few minutes before deciding
Select the finish and coverage that suit your skin type
Adjust shade seasonally if your skin tone changes
Use sample sizes or testers before buying full size
Ask for help from a beauty advisor if needed
