How many units of botox for eyes

The amount of Botox needed during a Botox treatment varies depending on a number of factors, such as what exactly is being treated and the size or area of the treatment spot. Botox is measured in units, and the number of units needed for your Botox treatment will determine how much it costs. And one of the most popular areas for Botox treatment is around the eyes. So how much Botox do you actually need when dealing with areas around the eyes? In cases of treating eye problems, the average dose is 12 to 24 total Botox units, with forehead lines requiring 20 units and crow’s feet requiring 24 units.

How botox cosmetic treatments work 

Botox is a protein derived from the Botulinum toxin, which is a neurotoxin produced by the bacterium Clostridium botulinum. Because of its strong properties, a plastic surgeon would recommend intramuscular injection (injected into the muscles) in small doses to avoid risks of serious illnesses. Over the past years, Botox injections has been used to treat medical problems such as: 

  • Overactive bladder – a condition characterized by increased frequency of urination 
  • Hyperhidrosis – excessive sweating caused by overacting sweat glands 
  • Dystonia – excessive muscle contractions
  • Chronic migraines – headache episodes that occur at least 15 days a month 
  • Strabismus – a condition where the eyes look in different directions  
  • Blepharospasm – involuntary blinking or twitching of the eyes 

As a cosmetic surgery, Botox is used to minimize and soften the appearance of wrinkles, fine lines, and skin sagging brought by aging. Repeated muscle movements or contractions is the main reason why creases appear prominent in the face. An injection of the botulinum toxin into the skin would block certain nerve signals sent to the facial muscles, causing them to weaken or paralyze. As a result, the skin would remain smooth and avoid unwanted wrinkles.

What is a botox unit? 

A unit of Botox is a measurement of the amount of neurotoxin that is injected into the skin. They are an indicator of the strength of an injection or how effective it will be in relaxing the targeted muscle. A Botox vial produced by Allergan (the company that created and markets Botox) contains 100 units and these are typically divided as required by the procedure. 

An in-person consultation with a plastic surgeon will help to determine how much Botox units a client will receive. In cases of using Botox injectables for the face and eyes area, the following guidelines set by Allergan are observed: 

  • Forehead lines – 20 units, with 4 units injected on five sides. When treated in conjunction with glabellar lines, another 20 units are injected for a total of 40 Botox units. 
  • Crow’s feet or lateral canthal lines – 4 units are injected into 6 injection sites, totaling for an average of 24 Botox units. 
  • Frown lines – 20 units, with five injection sites (one injected between the eyebrows and two injections placed above each eyebrow). 

It is important to consider that every client may react differently to the treatment. Depending on certain risk factors, some women may require more units than others. In cases of males, their facial muscles are stronger and would need more units than normal. For example, they could need 15 units on each side to treat Crow’s feet as opposed to the 4 units per side for females. For frown lines, they may also be injected with 30 units compared to the usual 20 units.  

Aside from the gender, the prescription of Botox injections may also be affected by other considerations including:

  • Age – Botox is typically approved for individuals who are 18 years and older. Patients who are in their mid to late 20s or early 30s are also good candidates for preventative Botox injections since most signs of aging begin at that period.
  • Metabolism – Differing levels of metabolism affects how long the results of Botox treatment will last. Those with high metabolism may regenerate their nerve muscles faster, causing the toxin to wear off. 
  • Facial muscles – People who have repeated facial expressions such as laughing, squinting, or frowning can affect the results of the Botox treatment. Likewise, clients with thick facial muscles may need more units since it may take time to penetrate and affect the nerves. 
  • Severity of wrinkles – The deeper the wrinkles, the more Botox unit is required to reduce its appearance. 

Reasons why botox is needed for eyes

Among the different parts of the body, the skin on the eyelid is considered the thinnest at less than 1 mm thick. The eyelid has two folds mainly the upper eyelid and lower eyelid. It is connected to the muscle known as orbicularis oculi which is responsible for the movement of the upper and lower lid. 

Despite its thin structure, the eyelid is still made up of complex parts including ligaments, blood vessels, fat pads, and nerves. Over time, changes can occur to these components, making them more vulnerable to different eye disorders and the various signs of aging. Under eye wrinkle and fine lines are among the most common symptoms that naturally occurs as a person ages. Other reasons why clients would seek cosmetic treatment for the eyes include: 

1. Crow’s Feet  

Wrinkles can be classified into two main types: static wrinkles and dynamic wrinkles. The former is characterized as creases that show even when the person is immobile and the face is at rest. It appears naturally due to the decline in collagen production loss of normal skin elasticity. Meanwhile, the latter type of wrinkles is formed from muscle contraction due to repeated facial reactions such as smiling, frowning, and laughing. Crow’s feet is a prime example of a dynamic wrinkle. 

Crow’s feet, also called lateral canthal lines or smile lines, develop near the outside corners of the eyes. When a person expresses their happiness or sadness, there is a tendency to blink the eyes and trigger the muscle to constantly move, which makes wrinkles and lines appear more defined. It may also be worsened by exposure to sun damage (UV rays) and certain lifestyle factors such as smoking. 

Beauty products like topical eye creams and anti-aging moisturizers are easy fixes that can minimize the appearance of facial lines when applied around the eyes. Chemical peels which use chemical solutions such as salicylic acid, glycolic acid, and lactic acid may also restore the skin’s youthfulness and make it look healthier. Botox injections also work to paralyze the muscles surrounding the eye area which cause Crow’s feet to smooth out over time. 

2. Forehead Line 

This condition is characterized by the appearance of horizontal forehead lines which is caused by the contraction of the frontalis muscle. This forehead muscle usually moves when a person raises their eyebrows, pulling the skin up and making lines show. It’s a natural action that most people do when they are conveying shock, fear, and excitement to certain situations. 

Forehead wrinkles may also be referred to as glabellar lines or forehead furrows. Glabella is the skin on the forehead, just between the eyebrows and above the nose. It also manifests when an individual makes repeated expressions that forces muscles to tense. They may also be caused by certain factors such as age, genetics, loss of hormones that keep skin tight, and exposure to free radicals from pollution and UV rays.  

Botox and soft tissue fillers (dermal filler)  are considered as treatment alternatives for most forehead wrinkles. It’s also important to stay moisturized and hydrated, practice frequent usage of sunscreen, and consume nutrient-rich foods to maintain healthy skin and slow down the symptoms of aging. 

3. Frown Lines

Frown lines are often mistaken for glabellar lines as it also develops on the forehead. But compared to the glabella line, frown lines are vertical marks that run between the eyes and adjacent to the eyebrows. In some people, they appear as deep creases that stretch from above the side of the nose to above the eyebrows. They are also known as the “11” lines because of their look that resembles the number eleven. 

Like most wrinkles, they form due to repeated exaggerated expressions such as frowning, squinting, or knitting of the brows which causes the corrugator supercilii muscle (small muscle near the eye and located between the end of the eyebrows) to contract. Botox injections are used to soften these muscles that cause frown lines. 

How Long Botox Results Last 

Since it’s a non-invasive surgery, the treatment usually takes 10 to 15 minutes and clients can return immediately to their normal activities Depending on the seriousness of the eye problem, the results of Botox injection can start to show after a few days and may last for about three to four months for most people. Follow-up sessions may be performed if a client wants to maintain long-lasting benefits of the injection. 

The common aftereffects of Botox include swelling or bruising around the eyelid area, headache, dizziness fatigue, nausea, dry eyes, and temporary muscle weakness. Most of the side effects are minimal and usually go away after a few days. However, immediate medical care is required if the symptoms persist and worsen.

How Many Units of Botox Do I Need?

How Many Units Of Botox 3 1 1 Nazarian Plastic Surgery

The number of Botox units used during Botox Treatments will not be the same for everyone. Units of Botox will be customized for each individual, according to gender, the area of treatment, the strength of your facial muscles and anything else that may influence the amount of Botox that you need. Nazarian Plastic Surgery offers Botox Treatment at our Beverly Hills Office.

Many patients wonder, “How many units of Botox do I need?” This article will provide you with a guide to help determine the right form of treatment and the appropriate amounts needed to provide you with optimal results.

Your Guide to Botox Injections

The most common areas for Botox treatment are the forehead, crow’s feet, and the frown area. No matter where you get your Botox from it will always be measured out in units. Allergan is the maker of FDA-Approved Botox (botulinum toxin), and it has set guidelines for cosmetic professionals. According to Allergan’s guidelines, the following units should be given:

  • Crow’s Feet – 10 to 12 Botox Units per eye (2 eyes would mean 20 to 24 units)
  • Frown Lines – 20 Botox Units
  • Forehead lines – 20 Botox Units

You can get multiple Botox injections during your visit. So, if you were looking to get all three areas done you would need a total of 64 units. This may be less depending on the severity of the area of treatment. This is merely a guide; your cosmetic professional would make their recommendations during your consultation. You must listen to their suggestions and get all of your questions answered.

Read below for a general outline of Botox units. 

Botox Treatment

Like many other cosmetic treatments, Botox (bacterium clostridium botulinum) must be injected in just the right way into the right injection sites for best results. Effective treatment can give a more youthful appearance, but the injection specialist or plastic surgeon can only provide effective treatment if the right injection site and dosage are used.

How Much Botox For Each Specific Area?

Smile Lines?

Botox Injections are not used for smile lines. Botox is a temporary muscle relaxer. Therefore, if you injected it into your smile lines, you wouldn’t be able to move your mouth. Dermal fillers can be injected into smile lines to fill in volume loss.

Between Eyebrows

How many units of Botox should be used between eyebrows? On average, 15-20 units of Botox are recommended for in between eyebrows.

Brow Furrow

15-20 units of Botox are recommended to mitigate furrowed brows.

Eyebrow Lift

Injecting 10-15 units of Botox into the crow’s feet on the side of the eyes helps lift the brow. A lot of people think that injecting Botox in the forehead lifts the brow, but that is incorrect.  

Botox in the forehead temporarily paralyzes forehead muscles. The job of the forehead muscle is to lift the brows so, if you paralyze it, the brows lower.  

Instead, injecting Botox under the brow and around the crow’s feet of the eye lifts the brow. The muscle that causes crow’s feet pulls the brow down. Paralyzing the muscle around this eye (orbicularis oculi) helps lift the brow.


Botox is not used in the cheeks. Many doctors recommend adding dermal fillers to the cheeks. 


Forehead lines can be treated with Botox Treatment. 5-15 units of Botox are recommended to treat fine lines on the forehead, depending on the size of the forehead or how much movement is needed.

Glabellar Lines

To diminish glabellar lines, doctors recommend 15-20 units.


How Many Units of Botox For Lips? Botox can be used in the lips to soften kiss lines. However, it also makes it difficult to drink out of a straw as that muscle (orbicularis oris) is temporarily weakened. Because of this, many doctors recommend using lasers or superficial fillers to help with lines around the mouth.

Gummy Smile

2.5 units are recommended on each side. This is recommended for patients whose smiles reveal their gums. The Botox relaxes the muscle down and creates a smile that shows all teeth and no gums. 

Crow’s Feet

Average units are about 10 for on each side to improve the appearance of crow’s feet.


10 units are recommended on each side, strategically placed into various injection sites. 

Frown Lines?

The average units used for frown lines (Lateral Canthal Lines) is 15-20. Because the muscles are very strong, more units are needed to combat these lines. For some individuals, more units may be required.

Bunny Lines

How many units of Botox for Bunny Lines? 10 units are recommended on each side. Anything less will not give the desired effect because the muscle is like a fan and treatment must hit the whole muscle.


How much Botox to treat facial wrinkles? This depends on which areas are treated and the injection sites. Refer to other questions for specific facial muscles. 

Marionette Lines

Botox is not used for marionette lines. Botox is a temporary muscle relaxer. If you injected it into marionette lines, your smile would be off. Fillers can be injected in front of the marionette lines to fill in volume loss and camouflage the indentation in front of the marionette.


This depends on a variety of factors. This is best answered by a neurologist.

Smoker’s Lines  

Similar to the lips, many doctors recommend using lasers or superficial fillers to help with fine lines around the mouth.


It is not recommended for patients to get Botox in the chin area. Botox around the chin can throw off the smile, as it is a wide muscle. As a result, some areas of the chin may move and other areas may not. If the patient has a lot of wrinkles on their chin, it may be because they have a weak chin and need fillers to build up the bone. 


The platysmal bands may stick out as you get older. You can check yours by making an exaggerated E sound with your mouth and looking for two lines on your neck. When activated, the muscle protrudes. Injecting Botox helps suck in the muscle and make it look taut. Doctors recommend anywhere between 20 to 60 units. 

Masseter Muscle

The masseter muscle is activated when patients grind or clench teeth. This can result from stress or simply be a bad habit. This may cause soreness in the jaw, lead to temporomandibular joint dysfunction (TMJ), or result in a wide look at the bottom of the face. Doctors typically recommend injecting 15-20 units on each side, which can promote a slimmer face and also act as functional relief because it combats symptoms of teeth-grinding or clenching. 

There are many areas that Botox injections can help treat. Patients need to do their research and consult with a doctor who can answer their concerns and questions. The doctor will help the patient come up with a personalized treatment plan to meet their goals. 

Everyone Has Different Needs

The number of units that you will receive will be based on your individual needs. Some patients may need more than the recommended guidelines to treat severe fine lines and wrinkles.

Men tend to have stronger facial muscles; this means that it will take more Botox to penetrate those muscles. A man may need 15 units for each side to help treat crow’s feet. One thing is for sure, no two patients are alike and the units needed will be based on individual needs.

Sometimes Less is More

Your cosmetic provider will work with you to customize a plan that will help you work up to an optimal amount of Botox. It is always best to start low and work your way up. Especially if it is your first time getting Botox treatments. When you come back in for your two-week follow-up appointment more can be added if necessary.

Botox treatment will peak at two weeks, so this is the best time to look at the results that were obtained. It’s easy to add more units, but you cannot take them away once they have been given. Results can last up to three to four months. If too much Botox is given, you would have to wait for it to wear off.  The next time you’re looking for Botox treatments and wondering “How many units of Botox Do I need,” consult a plastic surgeon or an injections specialist.
