If 100 units of Botox is injected as opposed to 50, will the effects last longer? (Photo)

Hello, Thank you for your question.Typically the dose administered is based on your muscles' strength, activity, and density. It is improve that you receive the proper dose to relax these muscles; however, doubling your dose doesn't necessarily leads to a longer lasting treatment. Having routine treatments over a long duration of time, may make your results last longer. I recommend you book a consultation with a
qualified injector, to ensure you're a good candidate for this procedure.Take care. 

When dealing with very small doses, there is an increased duration of effect as the dose of drug is administered increases.  However there comes a point at which injecting more Botox will not increase the longevity.  There are some botulinum toxin products that

The number of units of Botox used controls how much the muscles will be relaxed, and to some extent how long the effects will last. It is very important to inject the amount of units necessary for the desired effect. Injecting too many units may result in an unflattering “frozen” look, could lead to unwanted side effects, and will last a bit longer but not twice as long. The only time I recommend using more units is to treat sweating. The more units you inject into the armpits or palms, the longer you do not sweat. The way to get the best results from Botox is to visit a skilled, board-certified dermatologist with experience injecting neuromodulators. 

Thank you for your question in regards to Botox.No, doubling the number of units to be injected will not increase the duration of Botox. Routine injections over the years will make the effect last longer. To be sure what is best for you, see two or more board-certified providers in your area for a complete evaluation to make sure you are a good candidate and that it is safe for you to have treatment.I hope this helps.

Higher doses last longer but nobody knows at which dose does the length of results stop.  At some point it will plateau.  It is better to get a normal dose and touch it up sooner than getting higher does at first which can give a "frozen" look.  Best, Dr. Emer.

Thank you for asking this good question. The greater the volume of Botox which is used, the more surface area can be treated. It will not increase the duration of effect. With repeat injections over years, the effect will last longer following the injections. I hope you find this helpful.

No.  The number of units is important only really in the areas that you can cover.  You should be injecting the number of units per injection that you have found to work.  The onset of action and the length of time it lasts is not affected by the number of units injected per area.

Supercharging your dose is probably just a poor use of your money. Botox works by temporarily destroying nerve endings to your muscles. There are a finite amount of nerve endings, so once their connections are blocked, the additional botox will not continue to work and will be cleared from the body. The only possible exception to this is if you have antibiodies to botox, which is rare. In this situation, it may require increasingly higher doses to treat the facial muscles.The most effective solution to stay ahead of facial lines is to plan on re-treating the Crow's feet area at 3 months, and the glabella and forehead at 4 months. Any sooner and you are not spending your money effectively.Best Wishes

No, it will not make the Botox last longer. What can help though is scheduling your first 3 Botox sessions at exactly 3-4 month interval. I've found that then subsequent session result can last longer, sometimes up to 6 months. Best, Dr. Nazarian

The amount of Botox does not determine the longevity. The units injected only makes the muscles more relaxed. I hope this helps.
