Which of the following best describes the purpose of establishing a brow midline during PMU planning?

• A. To balance overall facial features by providing a vertical reference.
• B. To decide the exact color shade solely.
• C. To determine skin type.
• D. To measure eyebrow hair growth rate.

Answer: (A)

Establishing a brow midline provides a central vertical reference to anchor brow planning, ensuring both brows are balanced with respect to the face. By marking the middle of the face, you can place the inner points, arches, and tails so they mirror each other and harmonize with the eyes and overall facial structure. This helps prevent one brow from appearing too high, wide, or off-center, which is essential for a natural, symmetrical look. Color shade, skin type, or growth rate aren’t determined by this vertical reference; those factors are assessed separately as you plan the PMU.
