Apply the foundation
Use a makeup brush to apply a darker shade of the foundation on either side of the bridge of your nose. Extend down both sides of your nose using the brush, beginning from the eyebrow and finishing at the side of the nostril. Make a dark coloured line on both sides of your nose. In order to make it look very natural, you need to blend it outward towards your cheek around the nostril under the eye.
Use a makeup brush to apply a thin line of a lighter shade of the foundation down the bridge of your nose. Blend it carefully and start between the eyebrows and move it downwards to the tip of your nose.
Brush the lighter colour
Having applied the foundation, you need to gently brush the lighter colour towards the contoured and darker side of your nose, which will help avoid any sharp lines. During this procedure, do remember that you should not lighten the contoured part. Light hits the bridge of your nose sharply, so using the lighter shade of foundation will make the slimmer part of your nose more prominent.
Dust some powder on the contoured nose
In order to eliminate any lingering lines and to finish the nose contour, softly dust some powder on the nose through a powder brush. Your wide nose is now contoured and will look thinner and more attractive.
