Gone are the days of the heavy rouge that our great-aunts wore. Blusher should be subtle, especially for daytime use, but can be a little brighter for evenings.
PLEASE NOTE:The blusher shown here is somewhat exaggerated for demonstration purposes only. Use it more subtly when you apply it.
With your face relaxed (not smiling) apply first to the "apple" of the cheek, starting at a spot shown in the diagram, where a vertical line from the outer corner of the eye meets a horizontal line from the bottom of the nose.
Then apply blusher lightly in a line aiming toward the top of the ear. Blend the edges of the colour with a larger soft brush.
