Shake the bottle well before dispensing a small amount onto the back of your hand or directly onto your face. Using a foundation brush, sponge, or your fingertips, blend the serum foundation evenly over your face. Start in the center of your face and work your way outward, using a tapping or patting motion to blend the foundation into your skin. Repeat the application process in areas where additional coverage is needed. Finish by applying any additional makeup products you typically use, such as concealer, blush, or setting powder. Remember to start with a small amount and blend well for a natural-looking finish.
