How Much Units of Masseters Botox to Start With?
My Doctor is compelling me to go for Masseters Botox, he said 2 sittings will be required, at first sitting he would inject 100 units of Botox at each side and after 6 months one more sitting will be required. I think 100units on each side is a high amount to start with, but my Dr says, for effects to show min 75units must be injected , less than that does not work. I have been reading here at realself people getting benefited from even 25units. Please guide me.

Botox 75 Units Per Masseter?
75 units of Botox per masseter is not necessary. The doctor is most likely referring to Dysport, which is about 3:1 Botox.

Botox and the masseter muscles
The number of Botox units required depends on the strength of your masseter muscles, your gender and the shape of your face. Most people benefit from 20 to 40 units per side. 100 Botox units per side is excessive. Did he mean Dysport units? If you are interested in treating your masseter muscles, either discuss the product and amount with your doctor or seek another opinion.

Depends on the patient
You are correct that 100 U on each side sounding excessive. Generally at a minimum we start treating at 20u/side, and increase all the way up to 50u/side depending on the size of the muscle. Perhaps they were referring to Dysport units, which would make more sense of 50-80 units per side. Have your physician clarify with you which toxin is recommended and the difference in conversion of units.

Appropriate dosage for Botox and Dysport for masseter reduction, "V-line" procedure
100 units for each side is excessive. You should notice a marked improvement with an initial treatment of 25 units per side. With serial treatments, even with 20 units per side it should be possible to virtually eliminate the activity of the masseter muscle causing the bulky appearance along your jawline.
Even for Dysport, 100 units is excessive. 50-70 units per side with Dysport produces excellent results.

Botox for jaw reduction
Dear pari1987,
I like starting with 30 units on each side and bumping up the dosage as needed
If you can still clench your jaw after 2 weeks, then we add more
Some people do start with 100units so everyone is a little different

Masseter requires much smaller dose
The masseter is a thick, somewhat quadrilateral muscle, consisting of two parts, superficial and deep. The fibers of the two portions are continuous at their insertion. The masseter muscle is sometimes the target of plastic jaw reduction surgery.The superficial portion, the larger, arises by a thick, tendinous aponeurosis from the zygomatic process of the maxilla, and from the anterior two-thirds of the lower border of the zygomatic arch. Its fibers pass downward and backward, to be inserted...

Masseter botox
I think that it is important to be conservative when injecting botulinum toxin in muscles that have important serve important functional or aesthetic purposes. This is particularly true when injecting around the mouth. The massester muscles serve important masticator (chewing) function. For this reason, it is important to not overinject these muscles. I start with 20-25 units per side. This leaves enough motion of the muscle to allow adequate function...

How Many Units of Botox for Jaw Reduction
Hi Pari. We agree that the dose being suggested is high. We use 50 units total, 25 units each side and set the expectation that the patient should return several times in a year. You may get longer duration with this higher dose, but it seems like overkill to us.

How many units of Botox for masseters?
I would agree that 100 units of Botox to each side for the masseter muscles seems high. I have had patients respond to as little as 20 units on each side. I'm not sure if your masseter muscles are very large or not, and this may be why your physician wants to use a higher dose.

Botox and masseters
Having a thorough assessment with a well-trained and experienced injector will give you plenty of options, including an assessment of your muscle size and strength which dictate units required to meet your aesthetic needs.
