Do you have frown lines or ‘scary lines’ that make you look angry, older, or worried all the time, even when you are not? That’s where Botox comes in as a solution without downtime, and without going under the knife.

How many units of Botox do I need?

One of the most popular questions about Botox relates to how much Botox someone needs. You are not alone, especially if you’re new to this cosmetic treatment.

Botox is measured in units, an arbitrary unit of measurement derived by animal studies that correlate to a fixed number of botulinum molecules.

Units measure the biologic strength of the Botox; it’s a scale to standardize the ability of Botox to relax the nerve.

Units are unique to Botox and are determined by Allergan, with all other neurotoxins and dermal fillers are measured differently.

Each vial of Botox contains 100 units, which can be split into individual blocks for treating various areas.

The ideal units of Botox for you can only be determined through a consultation with a board-certified cosmetic physician, and depends on the quantity, length, and depth of the patient’s lines because every patient is unique in terms of facial characteristics and desired result.

Some of the most well-known characteristics include:

  • Gender: Men usually have larger facial muscles compared to women and thus they generally need more Botox.
  • Facial muscle strength from repetitive actions like frowning, smiling, or squinting. Individuals who are more prone to these repetitions will require more Botox.
  • Wrinkle Severity: The more severe or deep the wrinkle, the more Botox will be needed for proper treatment.

Units also vary depending on your face shape, size, and your metabolism.

Most Botox providers use these guidelines as a starting point and customize a treatment plan for each patient, given the patient’s current condition and desired results we mentioned.

Here’s the recommended units of Botox needed to treat common areas:

  • Crow’s feet: 5-15 Botox units per side
  • Dimpled chin: 2-6 Botox units
  • Frown or Glabellar Lines: 15-25 Botox units
  • Eyebrows: 2-5 Botox units per side
  • Forehead lines: 10-30 Botox unites
  • Gummy smile: 2-4 Botox units
  • Marionette lines: 2-8 Botox units
  • Nasalis “Bunny” lines: 5-10 Botox units
  • Neck bands: 25-50 Botox units
  • Pout boost: 2-4 Botox units
  • Upper lip lines: 4-8 Botox units
  • Smile lift: 3-6 Botox units

Glabellar lines and crow’s feet are FDA approved. The rest are considered off-label uses.

Keep in mind that under treating an area may not leave a satisfying result and could end up costing you more money if a fix is needed.

An experienced and board-certified physician will determine the right amount of Botox needed to deliver the results you are looking for.
