How Many Botox Units for Horizontal Forehead Lines?

Dear Cabbie02 I am not a big fan of injecting BOTOX into the forehead. The muscle up there, the frontalis muscle is the only elevator of the eyebrows. This means that any BOTOX injected into the frontalis muscle will drop the eyebrow position. Yes one can certainly create a glass smooth forehead (Think Marcia Cross) but the price is a fall in the eyebrow position. The aesthetic price is very high because one gets this frozen forehead and a drop in the eyebrows that screams: MY... more

There is no set number for the number of Botox units in the forehead since every forehead is different. The number of Botox depends of various factors, including how deep the creases are, how big the forehead is, how expressionless you want the forehead to be etc... That being said, its also always a balance of injecting enough to get a good result without causing droopiness of the eyebrows and without looking too frozen. I am a true believer of putting less than more in the forehead and... more

The number of Botox units will depend on the number, length and depth of the forehaed lines.  We typically use between 16- 36 units of Botox for the forehead.

Every patient is different. Your washboard may involved larger muscle bands than another patient’s and the number of units may be higher. Some patients only get 10 units in their forehead and others can get 50. The number of insertions is also different patient to patient. See an experienced dermatologist or plastic surgeon to determine what your ideal treatment would be.

I will typically start with up to thirty units of Botox to the forehead alone to weaken the muscles. Some people have strong muscles and need more but at a first meeting with a patient, I will not know that. I have them come back in two weeks for a recheck and a booster if they need more Botox. Botox only weakens dynamic or mobile skin lines. Fixed lines that develop over time need to be fixed through other means such as: laser resurfacing, use of injectible filler, use of wire subcision... more

Hi! Of course, everyone is different, but this is the dose that we use for most patients in New York City.  Others use a little less, but I believe that if you use more, it lasts longer.

The answer is: as much as you need to improve the lines without dropping your brows. There is no pat answer to this question as everyone is different: different age, skin thickness, forehead height, is there redundancy of wrinkles?, etc, etc. Therefore, go to a board certified dermatologist, or plastic surgeon who can give you YOUR correct answer.

Depending on the length of these line determines how many units you will need.  I typically use 50 units on the forehead. I avoid the lateral brows to prevent sagging.  Most of my patients stay paralyzed for about 5 months with 50 units.

Dear Cabbie 02 The treatment of the forehead and glabella with Botox will depend on the position of your eyebrows, and the desired shape of your brows. It is best to treat the muscles that are pulling down on your eyebrows first then treat the forehead muscles so that your eyebrows do not drop. The rang in units can be 10 to 20 for most cases.

Frown lines between the eyebrows should probably be injected along with the forehead to reduce the risk of dropping the eyebrows with forehead injections alone. Since you have never had Botox to the forehead, I would start with about 10 units. You should be aware that if your forehead muscles are continuously working to keep your eyebrows up (we can usually tell when this is occurring), even 10 units to the forehead only could drop your brows. Good luck.

This would depend quite a bit on which sex you are. Males require many more units than females. The general configuration of your forehead lines would also be important. If your forehead lines extend all the way around and curve around the frontal region you would require a few more units to avoid the Dr. Spock look (for us SF fans), sometimes called the Jack Nicholson look (for Laker fans). There has been a marked tendency among dermatologists and plastic surgeons to decrease the number of... more

You would need to consult with a plastic surgeon in your area to determine how many units would be needed to treat your problem.  Generally though, about 20 - 25 units are needed to treat the forehead.
