Brows with a sharp arch naturally draw the eye upwards, which will give the appearance of a more youthful, lifted face. Be cautious of making your arch too high, it should still be proportionate to your face.
Full, flat brows are youthful and natural in appearance. This shape is also ideal for those with oblong faces because the horizontal shape will make the face appear shorter.
If you're unsure of how to do your brows, this shape should be your default. The soft angles are flattering on all face shapes. Be sure not to over tweeze; this shape is best when brows are fuller.
Ideal for heart-shaped faces, the gentle slope is ideal for creating a balance to the more narrow bottom half of the face.
