A frequently asked question about Botox is “how many units will I need?” Botox, a very popular injectable treatment for lines and wrinkles, is administered by the unit. Then, it’s also priced by the unit, so new Botox users often want to know how many units they’ll need before they come in for an appointment.

Unfortunately, it’s not possible to tell someone exactly how many units of Botox they’ll need before seeing them in person, examining their skin, and learning about their aesthetic goals. However, we can tell patients the average number of Botox units people get per area to give them a rough estimate of the number of units people usually get.

Below, we’ll break down these average Botox unit figures by facial part to help you understand how many units are usually used to treat each part of the face. Then, we’ll also talk a bit about the factors that can sway these averages, such as muscle strength, metabolism, and treatment goals.

Average Botox Units By Facial Part

Everyone’s face is different, as are their aesthetic goals. So the amount of Botox someone may need can vary greatly from person to person. However, to get a general idea of how much Botox people usually get, view our list of the average Botox units by facial part below. This list of average units can give you a baseline understanding of how many Botox units most people get, which can help you roughly estimate how many units you may end up needing.

Bunny Lines (Lines on the Nose): 5 to 10 Units
Chin: 4 to 8 Units
Crow’s Feet: 5 to 15 Units Per Side
Eyebrow Lift: 5 to 15 Units
Forehead: 10 to 30 Units
Glabellar Lines (The Lines Between the Brows, aka “11 Lines”): 15 to 25 Units
Masseters (Jaw and Cheekbone Muscles): 20 to 50 Units Per Side
Neck Bands: 25 to 50 Units
Smile Lift (Corners of the Mouth): 3 to 6 Units

Botox Units and You: Factors That Affect Averages

Muscle Strength

One thing that affects how much Botox someone will need is the strength of their muscles. Our muscles vary in strength in general. For example, the glabellar or “11” muscles are stronger muscles that require more units for everyone. But then, the personal strength of your muscles can also affect how much Botox you’ll need. If your muscles are stronger than average, you’ll need more Botox than average. Of note, men tend to have much stronger facial muscles than women, so they tend to need more units than women in general.


One thing that many people don’t realize affects Botox is metabolism. Our metabolism processes the substances we put in our body, including Botox. People with faster metabolisms tend to need to get Botox treatments more often, since their body breaks Botox down more quickly. And, just like with muscle strength, men tend to have faster metabolisms than women on average. So many men find that they need to both get more units of Botox and get touched up more frequently.

Treatment Goals

Your individual goals for Botox treatment will have a major impact on how many units of Botox you’ll need. Botox can be used in numerous different ways. For example, some people want to remove every wrinkle from their face and completely stop their muscles from moving, which requires more Botox. Then, to give another example, other people who want to use Botox minimally (or try preventative Botox) may just want to smooth a few wrinkles but retain most of their muscle movement, which may require a bit less Botox. Because Botox can be used in so many different ways, your unique treatment goals have perhaps the biggest impact on how many Botox units you’ll need.
