Hello, just wanted to ask how many areas dose 20 units of botox give on face? As in the UK is per bottle

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. Typically 20-25 units are used in your glabella area (between the eyebrows) 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.

The dose of Botox is individualized for each patient, but generally speaking, 20 units would be in the approximate range of treating one area of the face.  

Helloone area of botox is usually 20 units of botulim toxin, the upper face can be divided in 3 areas, the forehead is one area, the glabella(between the eyebrowns) is another area and the crows feet is another area, to cover the all upper face you need at least 60 units of botoxDr velilla

Botox is a fantastic treatment for wrinkles around the face.  Twenty units is the amount of Botox that is typically put into a given area such as the glabella.  For the best cosmetic results please consult an expert since it is not just the "units" injected but the proper placement of Botox or filler that is vital.  Best, Dr. Green
