How Long Does Botox Last?

In this section, we will be answering the main question of this article by considering the various elements affecting the longevity of Botox injections at the injection site. To know how long a botox treatment lasts, let’s take a quick look at the following important elements:


This is the first element in determining how long Botox lasts. The answer lies in what specific area of the face you’re focused on as well as the dosage used in that area. Botox is usually administered in different quantities of units at different injection sites on the face. When Botox is injected at a particular injection site, they are injected per unit. Therefore, the more units a muscle receives, the more the Botox lasts.


The dosage administered in the forehead area normally ranges from 10-15 units. Due to the high prescribed dosage for this area, Botox can potentially last anywhere from 3-6 months. Moreover, additional elements such as age and metabolism can affect the duration of the effect.

Glabella/Frown lines

This particular area normally requires 20-25 units to obtain the desired results. Botox treatment around this area can potentially last anywhere from 2-6 months.

Crow’s Feet

Botox treatment can also be used as a remedy for crow’s feet. This specific area requires 5-12 units per eye to achieve the desired results. Botox can potentially last up to 4 months post-injection.

Muscle Size/Strength

Another important element in determining how long a Botox treatment lasts is muscle size and strength. The most successful Botox treatments are tailored to a patient’s muscles. Weak muscles fight less against the injection site, unlike strong muscles. It is therefore advisable that a patient with weak muscles schedules a follow-up appointment every two months while those in with strong muscles can schedule an appointment in less than two months.


Botox injections are normally diluted with saline prior to injection. Adequate dilution will automatically result in an easy, safe treatment that will achieve the desired results. In a case where there is over-dilution, the impact of the boric injection wears off quickly.

Technical Experience and Skill

One of the best ways to ensure that the Botox treatment lasts is by choosing a board-certified plastic surgeon. The surgeon is experienced and skilled enough to know the quantity of dosage to administer as well as the proper handling and usage of the injection equipment. Their qualification also enables them to know how to achieve the youthful, fresh and radiant appearance that their patients desire.

Length of Use

Patients who continually use Botox injections over a long period of time will experience a long-lasting Botox treatment compared to patients that are fairly new to the treatment. The reason behind this cannot be fully explained but some presume it is due to the fact that the muscles are already used to the continuous dosage and relaxing effects of the injections.


Athletes are prone to a shorter lifespan of Botox treatment than non-athletes. This is because they have higher metabolism rates due to their frequent workout or exercises. This then causes their bodies to address foreign invasions faster than the bodies of the non-athletes. Once the body detects a foreign invasion which is the Botox, it attacks the solution and readily works to dissolve it. Therefore, athletes have to receive treatments more frequently than others.


Botox should be immediately stored in a cold place after use. Once it leaves its current cold environment, it can only retain its contents and composition for roughly four hours. It wears off sooner than expected when it is exposed for longer hours. Therefore, patients have to be certain that the Botox used during the treatment is fresh and new.

Gravity and Sun Damage

Botox can be an ineffective treatment in some instances. Instances where wrinkles were caused by sun damage or gravity, Botox treatment has no impact on such conditions.


Common Botox Treatments

Botox injections work mainly to prevent certain chemical signals that might cause your muscles to contract. They do this by blocking the signals from the nerves of this particular area of the face or body so they can stop functioning. The constant functioning of the nerves is what causes wrinkles but while there are unable to function, you are guaranteed smooth and healthy skin. Let’s take a quick look at the common areas for Botox use as well as the necessary treatments carried out in these areas.


Botox injections are used in the forehead to temporarily relax the facial muscles around that area. They are also used to treat hyperhidrosis around the forehead which is a condition that occurs due to excessive sweating. If you ever take note of frequent headaches as well, it might be a sign of chronic migraine. Botox injections are also used to treat frequent headaches that occur more than 15 days a month. The Botox treatment helps to reduce headache frequency after use.


The eyes are the most sensitive area of the face. Botox treatments also help to temporarily relax the muscles around the eye area where wrinkles can be noticed. This treatment can also help with a condition known as the lazy eye. The most popular cause of this condition is said to be an imbalance in the muscles surrounding the eye area which are responsible for eye positioning. Botox injections can also help you treat contractures and relieve you of muscles surrounding the eyes.

There are several other areas for Botox use such as the mouth (corner of the lips) as well as the neck and chin areas. The most common areas are the ones listed above which are more prone to wrinkles. Botox treatments are mainly used to fix uncontrollable muscular movements and drastically reduce the appearance of facial wrinkles while the other treatments mentioned above are the ones not related to cosmetology.


How Does Botox Work?

When the muscle nerves send signals to the brain, there is movement in the muscles present in that particular area of the skin. The brain later responds by passing relevant information across on how the muscles ought to react. This continuous process is what causes wrinkles formation.

Botulinum is a potent neurotoxin and is commonly called Botox. Botox works by restricting muscle nerve transmissions to the brain. Botox injections contain a toxin called onobotulinumtoxinA which can temporarily prevent the movement of the muscles. Thus, the brain is unable to respond and the injected muscles are held in position. When this occurs, the skin that covers cannot wrinkle or age rapidly.

Botox injections normally begin working two to three days after treatment. You might need to maintain the effect of the treatment by regularly booking appointments with the surgeon on a monthly basis. However, depending on the problem being treated, the impact may last for about three months or even longer.


How To Prepare For A Botox Treatment

Select your doctor carefully before undergoing any treatment. Botox injections should only be administered under a professional doctor’s care. This is very important so as to avoid unskilled and inexperienced doctors who can potentially cause damage to your body and good health.

We recommend that you choose a doctor who specializes in your condition and has enough experience in administering Botox injections. If you have no idea of where to select a good doctor you can make inquiries or ask for a referral from your primary care doctor.

Inform your doctor about any previous Botox treatment you had within the past four months. This is applicable to only those that have had previous Botox treatment.

In case you muscle relaxants, allergy medications, sleeping aids or you are presently under any form of medication, ensure that you inform your doctor as well before proceeding with the Botox injections.

Doctors usually do not recommend taking Botox injections as a pregnant woman or nursing mother. They also advise that Botox injections should not be administered to certain people that are allergic to cow’s milk protein.

If you take blood thinners as well, ensure that a few days before your appointment with your doctor you completely stop using those blood thinners. This is to minimize any risk of bleeding or bruising after post-injection.

Botox injections are usually performed in the clinic by a board-certified plastic surgeon. The plastic surgeon makes use of a thin needle to inject tiny amounts of botulinum toxin into the patient’s skin or muscles. The number of injections needed depends on several factors which will be discussed later in this article.


What To Expect Post-Injection

Botox injections are relatively safe with minimal side effects if used by a skilled and experienced doctor. However, going to an unskilled and inexperienced doctor can bring about some possible side effects and consequences. Possible side-effects of Botox include:

  • Excessive tearing around the eye
  • Inexplicable eye dryness
  • Cockeyed eyebrows
  • Droopy eyelids
  • Drooling around the mouth
  • Crooked Smile
  • Headache
  • Flu-like Symptoms
  • Pain, swells or bruises at the injection site

After receiving the Botox injection, there might be an instance where the injection spreads throughout the entire body. This situation is very unlikely and happens only on rare occasions. However, you should watch out for the following symptoms hours to weeks after post-injection to be certain that you are not at risk or to check if you are indeed at risk. The symptoms include the following:

  • Weakness of the muscles
  • Loss of bladder control
  • Speaking difficulties
  • Swallowing difficulties
  • Vision problems
  • Difficult Breathing

One of the ways to prevent the injection from spreading throughout the whole body is to avoid rubbing and massaging the injected area for the next 24 hours post-injection. You can carry out your normal daily activities after this.

A skilled and properly certified professional is who you need to avoid having the possible side effects and negative consequences mentioned above. As long as you can visit a certified expert, the doctor can properly advise you on the procedure and help determine if it best suits your current health condition and well-being. If it does suit your needs and current state of health you can be assured of a successful Botox treatment by the certified doctor.
