Hydrate your skin well and use a primer if necessary. The foundation adheres to the primer, preventing foundation from smudging throughout the day. The makeup artist's mantra is: work from the center outward. Start in the center, around your nose and cheeks, and blend the foundation towards your ears and jawline. The most important thing is to ensure there's no visible color difference by blending the foundation thoroughly.

Brush or fingers? According to makeup gurus, it's best to decide for yourself what works best. Fingers create a subtle effect; a brush provides slightly more coverage.
