Try matte bronzing powder underneath your cheeks and jawbone to make your face appear slimmer.
Another way of applying blush is my smiling at yourself in the mirror and applying the blush on the apples of your cheek & then taking it upwards.
In case if you feel that your blush vanishes almost instantly, apply a cream blush first and then immediately apply the powder blush with a fluffy brush over it. The blush will not budge from its place!
Apply cream blusher in light downward movements, to prevent it from creasing and specks of color from catching in the fine hairs on your face.
Try peach colored blush for a great sun-kissed look.
For tan or dark skin, apply shades of brown, dark mauve & maroon as a blush.
If you’re unsure where to apply blusher, gently pinch your cheeks. If you like the effect, apply blusher in the same area – it’ll look wonderfully natural.
