Botox is one of the most popular non-invasive cosmetic procedures performed today, and there’s a good reason why.

It’s the revolutionary cosmetic medication that reduces moderate to severe frown lines, forehead furrows, smoker’s lines, and crow’s feet, all without the fuss and hassle of invasive procedures. It’s quick, painless, and rarely causes any side effects.

If you’re considering Botox treatment, you may have a couple of questions about the procedure, such as ‘how long does Botox last?’

We’re here to give you the lowdown. Read on to learn just how long you can expect Botox to last after treatment.


How Long Does Botox Last?

Generally, the effects of Botox tend to last between four to six months after treatment.

Botox is also used for medical purposes such as treating migraines or reducing neck spasms, so in these cases, it tends to work for a shorter period from around two to three months.

If you’re receiving Botox treatment for the first time, it’s important to be aware that your first experience isn’t likely to result in long-lasting results.

It can take several Botox treatments before your muscles respond to the botulinum toxin.

But, after several sessions, you can expect the results to last longer as the skin has had more time to produce the collagen necessary to fill in those lines and wrinkles.

Frequency of injections shouldn’t occur anytime sooner than three months otherwise there’s a possibility of your body developing a resistance to Botox. If you do receive Botox on a regular basis, you may be able to go for longer periods between treatments of up to six months to keep up the momentum.


What Factors Affect How Long Botox Lasts?

Although Botox generally lasts between four to six months after the procedure, there are various factors that affect how long Botox lasts.


Dilution of the Dosage

Usually, Botox is diluted with 1 to 3 ccs of a saline solution but there can be a variation in the dilution depending on which area of the skin is targeted.

A more concentrated solution offers a more exact treatment, while a more diluted dose allows for the diffusion of the Botox into surrounding areas of the skin that could also benefit from the treatment.


The Freshness of the Product

Botox comes in a frozen powdered form, and saline solution is added to create a dilution. As Botox is more potent when it’s fresh, ideally it should be used within 24 hours of mixing.

While most reputable practices open and use fresh vials of Botox daily so their patients can receive the effective treatment, others may keep their vials for longer. Solutions can be used for up to two weeks after mixing.



Older patients possess less elasticity and a decrease of collagen production in their skin, plus they usually have deeper wrinkles and lines. This means that the effects of Botox wear off more quickly for older patients in comparison to younger patients.



Likewise, athletes and very fit patients tend to metabolize Botox more quickly, which means it’s eliminated at a faster rate.


The Area Injected

If Botox is injected into areas with larger muscles, such as the frontalis muscle on the forehead, it tends to last for a shorter amount of time than it would if it was injected into smaller areas like crow’s feet.

While Botox injected into forehead wrinkles is expected to last up to three months, into crow’s feet it should last up to at least four months.


Medical Conditions

As mentioned previously, Botox administered for medical purposes, such as the treatment of migraines, doesn’t usually last as long as it would if it was used for cosmetic purposes.


How Long Does Botox Take to Work?

Next, you may be wondering ‘how long does Botox take to work?’

Understandably, those receiving Botox treatment for the first time may eagerly anticipate immediate effects. However, many feel disappointed when they learn that the results aren’t instant.

Most patients will start to notice the effects of Botox treatment three to five days after their injections, with full results showing after 14 days.

This delay is because the body needs time to start reacting to the botulinum toxin. Due to this reason, many surgeons suggest that patients return after a fortnight has passed to check on the progress of the treatment.

There are some factors that can determine how quickly results show, too. For example, for patients with particularly deep facial muscles, it may take longer to notice and feel the effects of Botox treatment.

If wrinkles are already deeply etched, or you receive Botox injection when you’re older in age, treatment can take longer to notice. Even then, it’s unlikely that Botox alone will completely smooth the lines.

For very deep lines it can take up to a year of Botox treatment before the skin starts to look relaxed. In some cases, a dermal filler may be recommended to plump out the deep lines of the skin.


Booking Botox Treatment

Now you know the answer to the question – ‘how long does Botox last?’

Especially when used early in the aging process, as well as treating wrinkles and deep lines, Botox also helps prevent new wrinkles from forming.

While those older can use Botox to treat deep wrinkles, it’s most effectively used on wrinkles that haven’t quite developed yet and reduces the likelihood of them becoming moderate or severe.

By combing a Botox regime with a decent skincare routine, healthy diet, and a positive lifestyle, you can stop most wrinkles from worsening and prevent new ones from forming. Botox simply works wonders!
