How Does Botox Lift Eyebrows and Make Them Higher?

Muscle Mechanics: Why Relaxing Depressors Lifts the Brow

The eyebrow position is determined by a dynamic tug-of-war between elevator and depressor muscles. The frontalis — a broad, flat muscle spanning the forehead — is the sole brow elevator, pulling upward when you raise your eyebrows. Opposing it are four depressor muscles: the corrugator supercilii (pulls the medial brow downward and inward, creating vertical “11” frown lines), the procerus (pulls the medial brow downward, creating horizontal nasal bridge lines), the depressor supercilii (a small muscle that depresses the medial brow head), and the lateral fibers of the orbicularis oculi (pulls the lateral brow tail downward).

When a Botox eyebrow lift is performed, the physician selectively weakens these depressor muscles while carefully preserving frontalis function. With the downward pull reduced, the frontalis creates a net upward vector that elevates the brow. The lateral brow tail typically shows the most dramatic lift (2-4mm) because the lateral orbicularis oculi fibers exert significant downward tension that, once released, allows the lateral frontalis to pull upward unopposed.

The clinical challenge — and where expertise matters most — is avoiding over-treatment of the frontalis. If too many units are injected into the central and lateral frontalis to treat forehead lines, the elevator power is reduced and the brow actually drops rather than lifts. This is why the Botox eyebrow lift at RE:BERRY Gangnam uses a “depressor-first, frontalis-sparing” protocol: the depressors receive full treatment doses while the frontalis receives reduced or strategically placed units that smooth lines without compromising lift.

Evidence for Non-Surgical Botox Brow Lift Efficacy

Multiple peer-reviewed studies have confirmed the effectiveness of botulinum toxin for brow elevation. Research demonstrates that targeted injection of the glabellar complex and lateral orbital muscles produces consistent, measurable brow lift. A landmark study found that glabellar Botox alone produced an average brow elevation of 1-2mm, while adding lateral orbital injections increased the lift to 2-4mm. The effect is reproducible across patient demographics and becomes more pronounced with repeated treatment cycles due to progressive depressor muscle atrophy.

For patients who desire lift beyond what Botox alone can achieve, combining Botox brow lift with energy-based devices like Sofwave (₩990,000/100 shots) or Ultherapy Prime (₩490,000/100 shots) at RE:BERRY Gangnam addresses the tissue laxity component that contributes to brow ptosis. While Botox rebalances muscle dynamics, these devices tighten the skin and SMAS layer, providing complementary mechanisms of brow elevation that can achieve 4-8mm of total lift without surgery.
