How much Botox is needed?
Patients frequently ask us this question. There is no set amount of Botox Injections that is right for everyone. Differences between gender, size of facial muscles, metabolism of Botox, frequency of repeat injections and desired cosmetic effect, alter the amount of Botox needed for each individual. Generally accepted guidelines have been published that list amount of Botox in units to treat the most common areas. Most Botox providers use this as a starting point and customize the treatment plan for each patient.
How much Botox do I need for my frown lines?
The frown muscles (11s) are some of the strongest in many patient’s faces as some use them more than others! Typically at least 20 units of Botox is required but is may take 30 units to get good relaxation. Men have bigger frown muscles and usually require more than 30 units.
How much Botox do I need for my forehead?
The forehead muscle is broad and thin. Multiple, small Botox injections are required to relax the forehead. Usually this requires 10-15 units of Botox. In women the injections should be centered between the pupils which produces a brow lifting effect.
How much Botox do I need for my crows feet?
The circular muscles around the eyes produce the crows feet wrinkles. They are usually visible when smiling or squinting. Several small injections of 10-15 units of Botox per eyes will relax the muscles and reduce the wrinkles.
How Does Botox Work?
Botox is a purified protein that we use to relax the muscles of facial expression. It affects the nerves that supply the muscle and temporarily blocks them. Botox is measured in units. These units are measured on their ability to block these nerves. The good and bad thing about Botox is that these nerves repair themselves after 3-4 months and the muscles return to normal.
Botox and Gender
Men have bigger muscles than woman. This applies to facial muscles too. As a result, men require more Botox per area than an average female.
Size of Facial Muscles
Some people just use certain facial muscles more than others. Some of us are frowners and we develop bigger frown muscles. Some of us are big smilers or squinters and we develop bigger muscles around our eyes. Some of us purse our lips a lot and develop bigger muscles around our mouth. Since Botox works to relax these muscles, bigger muscles will require more Botox.
Once injected, the effect of Botox typically lasts 3-4 months in most people. However, there are a few where Botox will only last 2 months or sometimes more than 6 months. We cannot predict who will metabolize their Botox faster or slower than average.
Frequency of Repeat Botox Injections
Our advice to most of our patients is to repeat your Botox when 50% of the muscle action returns. We find that when this advice is followed, the length between Botox Injections can be increased. This is because the muscle is kept in a weakened state and doesn’t have a chance to recover. If the Botox effect is completely allowed to wear off, most patients start from square one.
So How Much Botox Do I Need: Desired Cosmetic Effect.
Our goal for most patients is to obtain a natural look with Botox injections. We want our patients to look rested, fresher and younger without a frozen appearance. Some patients want to have a more dramatic look and this naturally requires more Botox.
