As remarks Marykay official website, Well-groomed, defined brows can make your face look years younger.
Brush brows gently and tweeze along the natural brow lines. Here is how to use a pencil as a guide to create flattering arches:
Groom and Shape Brows
Hold a pencil upright along the sides of the nose. Your brows should align with your inner eyes. Tweeze any hairs outside of these lines.
Angle the pencil from the tip of the nose to the middle of the irises. This is where the highest point of your brows’ arches should be.
Angle the pencil so it touches the outer edge of the nose and intersects with the outer corner of the eyes. This is where your brows should end. Tweeze any hairs that extend past that point.
Expert Extra: Fill in Sparse Brows
Sparse brows can be filled in to make them look thicker. First, define the shape of the brows with a brow definer pencil in a shade lighter than your eyebrow color. Then, go over brows again with a pencil in a darker shade to emphasize the shape.
