How Long Does Botox Work?

Botox can last between four to six months before it wears off. This article explains what Botox is, how long it works, factors affecting longevity, and frequently asked questions.

Patients have turned to cosmetic procedures to enhance their general appearance and revitalize their skin. Botulinum toxin injections have gained popularity due to their potential benefits on the face. Ithelps patients fight aging signs like creases and wrinkles. Most patients are not interested in this appearance, so they receive the botox injection. Looking for an experienced, well-skilled, and qualified cosmetic doctor for safe and best results is crucial. Clients may begin to experience the effects of botulinum toxin treatments a few days after the procedure. However,full effects may be observed after thirty days. It is a temporary procedure. When its effects fade, patients can take an additional injection to continue enjoying the youthful appearance.

What Is Botox?

Many patients use botulinum toxin injections to give a youthful and attractive appearance. According to Bach &Simman (2022),  botulinum toxin injection helps reduce facial wrinkles and treat medical conditions like overactive bladder, excessive sweating, migraines, crossed eyes, and eyelid spasms. It is an effective and safe way to eliminate wrinkles when injected into small amounts. According to França et al. (2017), botulinum toxin treatment is obtained from clostridium botulinum bacteria. Botulinum toxin is injected into facial muscles like the forehead, crow’s feet, glabellar lines, bunny lines, and others to give them a smooth and youthful appearance. They weaken the facial muscles responsible for the formation of wrinkles.

How Long Does Botox Work?

Botulinum toxin effects do not appear immediately. Mingazova et al. (2022) suggested that when botulinum toxin injections into the facial muscles, it takes three to four days for patients to start experiencing the effects. The maximum results can take some weeks or a month to be noticed. According to Stonehouse-Smith et al. (2020), the effects wear off between four to six months after botulinum toxin treatments. The effects of Botox vary from client to client. How long the Botox starts working depends on the treated area. According to Li et al. (2016), botox takes a lot of time to kick in since it must get into the cellular level of the facial muscles to block the signal nerves resulting in the weakening of muscles. This results in a reduced and smooth appearance of wrinkles.

Factors Affecting How Long Botox Works

Here are factors affecting how long Botox work.


Patients who receive larger doses of botox enjoy the benefits of longer compared to those having lesser dosages. Most cosmetic doctors inject more conventional amounts into beginners. The amount is increased over time as a cosmetic doctor understands the amount of Botox the client can handle and tolerate.

Treatment Area

 The effects of botulinum toxin treatments and other neuromodulators fade more rapidly in muscles or regions that are often used. Injections around the crows’ feet and the eyes wear off quickly due to the blinking of the eyes or constant movement during the day.


Every patient’s metabolism is different. It affects how quickly Botox will start working and how long it will last. Patients with high metabolic rates, like extremely fit clients or athletes, may experience shorter effects. This is because their bodies break down or metabolize the toxin more quickly than those with dormant lifestyles. Physical activities and daily exercises increase the metabolism rate.

The experience of a  cosmetic doctor may also play a big role in how long botulinum toxin treatments work. This is the first thing to consider when thinking of Botox. Berry (2021) revealed that an unprofessional cosmetic doctor might inject botulinum toxin injections deep into the skin tissues, hitting the blood vessels, which leads to bruising and swelling in the treated area. This can also lead to complications and uneven results. Patients should be careful when selecting a cosmetic doctor to treat them.

The number of injections affects how long botulinum toxin injections work. Touch-ups make results last longer. Planning consistent appointments can help patients achieve the long-term desired effects.

How to Increase the Longevity of Botox

A cosmetic doctor gives patients guidelines to follow to make their botox settle faster and last longerafter treatment. Clients should avoid strenuous exercises after botulinum toxin injections. This is because they can trigger sweating, increasingthe chances of infection since the bacteria can penetrate easily into the injection site. Adamian et al. (2020) claimed that some exercises, like yoga, may cause the migration of Botox to the nearby muscles causing complications.

Patients should consume a lot of water and eat fruits and vegetables. This helps in keeping the body hydrated and speeds up the healing process. They should avoid taking salty foods since they dehydrate the body. Šoštarić et al. (2022) claimed that eating well and staying hydrated makes Botox last longer.

Cosmetic doctors also advise clients to stop excessive sun exposure. Sun rays increase the wrinkles formation on the face. Whether or not patients have undergone botulinum toxin treatment, they should avoid excessive sun exposure. They can wear sunscreens or other protective clothing outdoors to prevent direct sun rays.

Patients should also avoid smoking and taking alcohol after receiving anti-wrinkle treatment. According to Bjørklund et al. (2022),nicotine in cigarettes triggers collagen breakdown, destroys skin cells, and minimizes the efficiency of botulinum toxin treatment. Smoking causes lines around the lip. According to Heydenrych et al. (2018), it acts as a blood thinner and opens up the blood vessels increasing swelling in the injected area. Patients should avoid smoking, vaping, and taking alcohol after receiving the anti-wrinkle injections.
