Is 10 Units of Botox Per Side Too Much for Crows Feet?

I am in my early thirties and I do not get regular botox. I don't have any lines around my eyes at all unless I smile. The first time I got botox was 2 years ago and the doctor only gave me 5 units per side and it looked fine. When I went in 2 weeks ago, he gave me 10 units per side. Is that too much for someone my age? It's only been 2 years, and honestly I don't think I have aged that much.

How much botox for crows feet.

Thank you for your question. I do not think that i would have given you botox if you "do not have any lines around my eyes at all unless I smile".  Lines that appear around the eyes when smiling are very natural, normal and are not necessary a bad thing.

The amount of botox given to you for the crows feet area is within the normal dose range for this area. The amount of botox given will vary from person to person. The reason for this is that the amount of muscle that is present is different from person to person- more muscle requires more botox.

  10-12 units of Botox per side represent a typical treatment for crowsfeet.  I think the best time to start treating areas is before permanent creases form in the skin.  In cases of poor outcomes after Botox, it is typically the result of placing the medicine into the wrong muscle groups rather then using too many units.

Hope this helps.

Both dosages are reasonable.  We know that higher doses of neurotoxins give you more effect, but also more duration.  So it may have been that the increase was coincidental, or motivated by an attempt for improved effect and/or duration.  A national consensus panel suggested 5-15 units per side a few years ago, so you are right where you are supposed to be.  But you need to be involved in such changes in treatment, so either ask your doc about why you were increased, or make sure you discuss this before your next injection.

Thanks for the question. Botox is an excellent option for treatment of the crow’s feet.  Allergan, the maker of Botox, typically recommends 12 units per side, but many physicians and nurses inject between 7-13 units per side depending on the individual patient. Botox is a very customizable treatment, and the appropriate dose should be determined by a qualified provider during a consultation.

How Much Botox for Crow's Feet

The amount of Botox that I give for crow's feet depends on how severe the lines are.  In a young patient with early or mild lines, I might give 5 or 7.5 units per side.  In someone with more obvious crow's feet, I usually give 10 units per side and sometimes slightly more. It would be rare for me to give more than 12.5 units per side.

5 units per side is definitely on the low end but it can work for people with mild lines.  I would say that 10 units per side is fairly typical and works well for most people.

That's the average

Do you like your results? If you do, then 10 units was probably not too much. In fact, 10 units is a typical quantity administered for this concern. Enjoy your results!

There's some confusion here...botox works on the crow's feet which aren't necessarily

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

the same thing as your smile lines...the smile lines to the side of your eyes result from raising the cheek muscles...but botox works on the muscles encircling the eyes...there's a big difference...try this simple for a moment and then while then squint you're still smiling...see the if the 5 units of botox worked well for the squint, that maybe enough and the rest will be all depends if you were happy the first time...if you were, then 5 units is perfect...if not then you need more...for those with significant creases in the area, you might need an average of 11 units or so per side...but works for the crow's feet and not the cheek...

The amount of Botox required depends on the movement of your muscles.  10 units per side is average and will probably last longer than 5 units would.  Botox treatments can prevent crow's feet from ever developing so it is a good idea to start early.  Make sure you are treated by an experienced injector.

10 units of Botox for crows feet is NOT too much!

Dear Patient,

10 units of Botox per side is definitely not too much. Dosages may vary between 10 - 20 units per side. It all depends on your muscle activity and the number of lines you have.
