For one thing, you could be using the wrong brush.
“Blush-specific brushes were created for a reason,“L’Oreal’s makeup blogexplains.
“They are designed to give you perfect, angular program every time.

double-check you pick the correct brush for your blush pop in and formula.
It might also be a question of where you’re applying the blush.
It should be on the apples of your cheeks.

Anywhere else, and you’re risking becoming a makeupcautionary tale.
Apply too high, and you might look clownish.
Apply too low, and you’ll look older.
Too close to your nose,The Skincare Editexplains, and you’ll look like you have a cold.
“For round faces, wear the blush along the cheekbones to create a natural looking contour.
For heart-shaped faces, apply blush right under the apples of the cheeks.
And for square-shaped faces, focus the blush right on the apples of the cheeks.”
Be sure not to use too much blush either way.
I recommend applying your blush in natural daylight.
