Is the price difference for Botox noticeable?

Is the price difference between imported and domestic Botox noticeable?

When I looked into getting square jaw Botox, I found that the price difference was quite a bit more than I expected.

I've noticed that foreign Botox products like Xeomin or Allergan are usually priced much higher than domestic ones. Is this simply due to the brand difference?

Or I am curious if the price of Botox varies like this due to the purity of the ingredients or the probability of developing resistance.

I’m curious because some say it’s okay to start with an inexpensive domestic product when first getting it, while others say that a product without resistance is better in the long run.

I would like to know what you consider a reasonable price range for Botox relative to its performance, and whether there is a compelling reason to insist on foreign products.
