Dark and light powder of liquid foundation
Different shades of cream concealers
Contour and highlighting powder
Using a lighter shade of foundation/concealer/highlighting powder (around 2 shades lighter than your original shade), apply a thin line starting between your eyebrows extending it all the way down to the tip of your nose with a tiny brush.
The light hits the bridge of your nose area first, so applying a lighter shade of foundation/concealer/highlighting powder will draw attention to the nose bridge which makes it "appear" slimmer!
Using a darker shade of foundation/concealer/contour powder, apply it on either side of the bridge of your nose starting from the eyebrows ending at the sides of the nostril.
