Hi Gavin,
i was just wondering how many units are typically needed when applying anti-wrinkle injections to the masseter in order to attain the effect of a slimmer face?
also do you perform this procedure regularly with good results?
Thank you!


Generally, I use 50 units. The amount used however, depends on the strength of the muscle.

We do a lot of masseter treatments and the results are excellent.

We have a page on it, there are some before and after examples and more info;
