Neurotoxin injections have become incredibly popular through the years. In fact, it is estimated that now 4-5 million people each year get Botox or other neurotoxin injections, which presents a steady increase in the demand for this minimally invasive treatment. The age demographic that has sought this treatment type out the most are people aged 40-45 with over 2.5 million people having it done in 2020. The second largest group was people between the ages of 55-69, who had over a million neurotoxin treatments done in the same year.

Despite the increasing number of folks seeking this service, there are still a lot of unknowns for consumers when it comes to Botox and similar injectables—like how many units are needed and at what frequency. Understanding the basics about neurotoxin injections will help you make the most out of your treatment and achieve the desired results you want.

Is Botox Right For You?

Because Botox and similar neurotoxin injections are so effective, many people make appointments to get the treatment administered. However, Botox and its competitors are not always appropriate to achieve the desired results. So, it is important to first set up a consultation with the injector to discuss your overall aesthetic goals to see if other treatment types are more appropriate. Since everyone responds to Botox differently, your injector will determine how many units are needed and will watch how you respond to the treatment so that they can adjust the dosage as needed.

Neurotoxins like Botox offer a range of applications including preventing and minimizing fine lines and wrinkles on the forehead, crow’s feet, and the lines around the nose. Botox can also help address drooping eyebrows, downturned lips, and chin dimples. While this treatment can be used to address a variety of aesthetic (and medical concerns), it is typically utilized to treat wrinkles on the forehead, between the eyebrows (11’s), and the corner of the eyes.

How Many Units Of Botox Do I Need For My Forehead?

One of the most requested areas of the face Botox is requested for is the forehead. Neurotoxin injections minimize existing fine lines and wrinkles on the forehead and give the skin a smoother tighter appearance, while also helping to prevent the formation of new lines. Depending on your goals and current skin condition, your injector will come up with a customized treatment plan to help you achieve your goals including the injection location, dosage, and the frequency needed to maintain the results.

When it comes to the forehead, there are five main injection sites including directly beneath the hair line, one in the center of the forehead, and two by the temples Since everyone’s facial anatomy is slightly different, it is important that the injector have a firm understanding of the anatomy of the face and the movement of the muscles so that they know exactly where to inject the neurotoxin.

As a rule of thumb, Botox suggests four units for each injection site, with 20 total. However, most dermatologists who perform this treatment typically utilize 10-50 units depending on your needs and history with neurotoxins.

At your first appointment, your injector may inject a lower dosage consisting of one-two units per injection site to establish your response to the neurotoxin. They will most likely want to make a follow up appointment within two-three months to assess your body’s response and adjust accordingly. Once your dosage is established, maintenance injections will be needed every three to four months to maintain the results.

How Many Units Of Botox Do I Need For My 11’s?

Another highly requested area to treat with neurotoxins is the frown lines between the eyebrows, also known as 11’s, which can be quite deep. Botox and similar neurotoxins offer a highly effective treatment to minimize existing wrinkles in this region of the face as well as prevent them in the first place if the treatment is started early enough (like in the 30s).

Botox recommends five locations along the upper brow and between the eyebrows. Again, the injector needs to thoroughly understand where the muscles of the face originate and insert to be able to analyze your facial movement to determine exactly where the injections should be performed.

The suggested units for this area by Botox are five units per injection site (25 units total) to achieve results, but the average is between 20-50 units total in this region of the face.

A slightly lower dosage may be used initially to determine the right amount of neurotoxin needed to address your concerns. However, once that is established follow up appointments are typically scheduled every three to four months to maintain the results.

How Many Units Of Botox Do I Need For My Crow’s Feet?

When it comes to the delicate area around the eyes, the wrinkles, and deep lines common in this region may require a more aggressive treatment approach. However, an injector will not want to utilize more neurotoxin than needed. To establish the right number of units for you, the process may take a little trial and error. Your injector may initially start off with lower dosages to ensure you achieve your aesthetic goals safely. Each person’s Botox plan will be a little different depending on the extent of the wrinkles, their anatomy, and their response to the neurotoxin.

There are six injection sites that Botox recommends to address 11’s including the outer corner of the eye, above and below the eye, and midway between the two. Again, each person’s face is slightly different so there isn’t one way to treat this area on the face.

Just like treating the areas between the eyebrows, the average is five units per injection site (25 total), but typically most injectors administer between 20-50 units depending on your specific skin needs and reaction to the treatment.

After your first treatment, your injector may have you come back for a follow up visit two months after your initial treatment to see how you responded and if any adjustments are needed to your dosage. Once that is established, maintenance appointments are typically every three to four months.


Botox and similar neurotoxin injectables offer a highly effective treatment option to prevent and correct fine lines and wrinkles on the face. While there are general guidelines for dosages, each person’s face is slightly different, so it is important to work with an injector who understands the anatomy of the face and how to assess your facial movements to address your concerns appropriately.
