Most patients need 10 to 30 units of Botox for forehead lines. At MDW Aesthetics in Brickell, the exact unit count we recommend depends on your muscle strength, the depth of your forehead lines, and whether you want complete smoothing or natural movement. At $10 per unit, forehead Botox at our clinic costs $100 to $300.

If you are researching Botox unit counts before your appointment, that's a smart move. Knowing what to expect helps you budget accurately and have a productive conversation with your injector. This guide covers unit recommendations for every facial area, what affects your specific number, and why the "right" amount varies from person to person.

Botox Units by Facial Area: Complete Guide

A typical full-face Botox treatment uses 40-64 units across the forehead, glabella, and crow's feet. Individual areas require fewer units when treated alone.

Facial AreaTypical UnitsCost at MDW ($10/unit)Purpose

What Affects How Many Units You Need

Your unit count depends on muscle mass, facial anatomy, treatment history, age, and whether you're seeking prevention or correction of existing lines.

When a patient sits in my chair, I evaluate several factors before recommending units:

  • Muscle strength: Patients with strong, active forehead muscles typically need more units (20-30) than those with lighter muscle activity (10-15). I assess this by asking you to raise your eyebrows and observing the contraction pattern.
  • Forehead size: A larger forehead surface area requires more injection points and more total units for even coverage.
  • Treatment goals: Some patients want complete smoothing where the forehead barely moves. Others prefer a natural look with reduced -- but not eliminated -- movement. The "frozen" look requires more units. Natural results require fewer.
  • Treatment history: First-time patients sometimes need standard dosing. Patients who maintain regular Botox appointments every 3-4 months may need slightly fewer units over time as the muscles respond to consistent treatment.
  • Gender: Men typically have stronger forehead muscles and require 20-40% more units than women for the same area.

"Natural results are not an accident," says Lisa MacLachlan, MSN, APRN, FNP-C at MDW Aesthetics. "They require an injector who understands proportion, restraint, and your unique facial anatomy. I would rather start with fewer units and add more at a follow-up than over-treat on the first visit."

Why Treating Only the Forehead Can Be Tricky

Treating the forehead alone without addressing the glabella (frown lines) can cause brow heaviness. Most injectors recommend treating both areas together for balanced results.

The forehead muscles (frontalis) lift the brows. The glabellar muscles (corrugators and procerus) pull the brows down and together. When you relax only the forehead muscles with Botox, the glabellar muscles keep pulling downward unopposed. The result can be brows that feel heavy or drop slightly.

This is why I typically recommend treating the forehead and glabella as a pair. Combined treatment produces balanced, natural-looking relaxation without heaviness. At MDW Aesthetics, a typical forehead + glabella treatment uses 25-55 units total ($250-$550 at $10/unit).

The MDW Approach to Forehead Botox

Every forehead Botox treatment at MDW starts with a muscle assessment, uses precise mapping of injection points, and includes a complimentary 2-week follow-up check.

Our process in Brickell:

  1. Assessment: You make facial expressions while I study your muscle movement patterns. This reveals exactly where the strongest contractions occur.
  2. Mapping: I mark specific injection points on your forehead using a white pencil. Each patient's map is unique.
  3. Injection: Small doses of Jeuveau are placed at each marked point. The entire forehead takes about 5 minutes.
  4. Follow-up: At 2 weeks, we evaluate results. If you need a touch-up, we add a few units at no charge during the adjustment period.

This approach ensures you receive exactly the right amount -- enough for smooth results, not so much that you lose natural expression.
