Broad and narrow jaw

If you have a very broad jaw, then the best way to mute it is to apply a darker shade of blush or a bronzer on the sides of your jaw, as these are usually the areas that come across as the heaviest. Such smart contouring works wonders to create an illusion of a shorter and smaller lower jaw area and a larger and wider upper face, that balances out well. On the contrary, if you have a narrow jaw that you want to make appear broader, then use a lighter shade of foundation or blush on the same area to highlight it, as it will then give you the opposite effect or a broad jaw.
Corrective Contouring on a Broad Jaw Line
If your client’s jaw line is broad, then the main purpose is to make it appear smaller and shorter, so that it does not come across as heavy.
Step 1: Take your 127 Blush Brush and dip it either into a dark shade of powder/blush/bronzer. Apply this color at the sides of your client’s jaw, taking it upwards till right next to her ears. This will give the illusion of a shorter or smaller jaw area and a larger and wider upper face.
