There are a few different ways you can apply your blush. Whilst some methods work better on certain face shapes, don't feel like you should be bound by the rules. Play around and see which method you prefer.
Method 1 - Apply blush up the cheek bones to the temples
This method is great for those with rounder faces as it lifts the face and adds definition to the cheek bones. Avoid putting blush on the apple of your cheeks, as this can emphasis any fullness you may already have there.
Method 2 - Apply blush only to the apples of the cheeks
To soften a square face, apply blush only to the apples of your cheeks. This creates fullness. To find the apples of your cheeks, just smile. Be careful not to exaggerate your smile when applying blush, as this can lift the apples of your cheeks higher than where they naturally sit, meaning that when you stop smiling your blush will be too low.
Method 3 - From the apples of the cheeks, blending horizontally
If you have a narrow, oblong face, you're going to want to add a bit of width to it. To create the illusion of a wider face, begin by applying blush from the center of the apple of the cheeks. Then blend this horizontally towards the ear.
Method 4 - Apply to the apple of the cheek and blend up the cheek bone
This works well for many face shapes. Start on the apples of the cheeks and blend up the cheek bones to the temples. This creates a little fullness in the cheeks, as well as defining the cheek bones.
Bronzer should be applied where the sun would naturally hit and tan the face; on the forehead, cheekbones, nose, and chin. However, if you have a super sparkly bronzer, you may just want to highlight the cheeks.
