Diffrence between 20 unit botox and 40 unit?

You should definitely see first how many units you’ll need for your particular concern. 20 units may be enough, or you might need more - it all depends on your concern. I suggest you also read the fine print of your offer. See if you need to use all of your units at once, or if you can save the unused for later. For your safety and satisfaction, go to an injector who you can trust, rather than one who’s the cheapest.

The amount of units required for a Botox treatment is determined by the number of areas to be treated.  A typical treatment will consist of 20 units of Botox per muscle acting area.  In other words, it is 20 units to treat the glabella (the area in between your eyebrows), 20 units to treat the forehead, and 20 units to treat the crows feet.  Hope this helps!

Thank you for your question in regards to Botox. The number of units required are based on the number of areas you plan on treating. 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.

I suggest you use the number of units needed for the type of muscle and shape you have. I suggest speaking to your physician for the best number.  Best, Dr. Emer.

If the 40 units is a better deal, go for it!!!  You may not need at a single treatment but use the remainder in a few months, if that is allowed.  Your injector should be able to inform you about how much you will need during a single injection visit and let that guide your decision.  Best of luck.
