In average, about 10 units of Botox will do it. There is no absolute rule and it depends on how much muscle activity you have and how much brow laxity you have.
You don’t want to use too much Botox if your brow laxity is too much because you may end-up with heavy looking brows, etc.
The best is to try a small amount first and see what result you get.
You may also need superficial injections with an HA filler like Belotero for the edge lines in your forehead if they are as deep as you say.
Botox works great for dynamic wrinkles, but those present at rest are better treated with a combination of neuromodulators and fillers. (Jose Rodríguez-Feliz, MD, Miami Plastic Surgeon)
Botox Is Injection That Is Primarily Used In The Upper Face To Relax Wrinkles And Fine Lines
The average amount of units can be anywhere between 6–20 in women. Men typically require more units however this can vary person to person. (David L. Robbins, MD, FACS, West Des Moines Plastic Surgeon)
The three most common sites to have Botox are the frown lines, squint lines, and horizontal forehead lines. The number of units required to soften these lines can vary depending on what is required and the strength of each muscle group.
On average, 30 units of Botox used in the frown lines, 30 units of Botox are used in the squint lines to raise the lateral brow, and 15 units of Botox is used in the horizontal forehead lines to soften the wrinkling. (David A. F. Ellis, MD, Toronto Facial Plastic Surgeon)
Units of Botox for forehead
Charge For Botox Treatment Per Unit
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 I’m not a big fan of the frozen look.
I have a lot of patients that are always in front of the camera and I don’t want them to be expressionless. That being said, my starting out average is about 7.5 to 10units per person.
How Many Units Of Botox Will You Need And What Is The Cost
If someone wants it frozen (which I don’t usually recommend), I will go up to 12 or 15 however I always also inject 2.5units in the lateral eyebrow area to combat the possible heaviness from the injection in the forehead. (Ben Behnam, MD, Santa Monica Dermatologic Surgeon)
Botox in the forehead can achieve a really wonderful relaxed look. The number of units can vary depending on each individual and how strong their muscles are. It typically can average between 20-30 units to achieve a natural look. (Parrish Sadeghi, MD, Santa Monica Dermatologic Surgeon)
10-12 units of Botox can magically smooth the forehead in a majority of cases.
Great at care and experience helps. Too much Botox laterally can drop the brow. (Luke J. Curtsinger, MD, Savannah Plastic Surgeon)
The Average Amount Of Botox Units Needed, Per Facial Area
Botox units will depend on how strong your muscles are
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 and injectible filler, and/or forehead lifting.
I recommend you see a board-certified plastic surgeon, dermatologist, or ENT/facial plastic surgeon to determine what procedure or combination of procedures would help you best attain your aesthetic goals. (Manish H. Shah, MD, FACS, Denver Plastic Surgeon)
Botox for Horizontal Forehead lines
Botox for Horizontal Forehead Lines has marginal benefit. For many patients, it will not be cost effective. The Horizontal Forehead lines generally requires 20 to 60 units of botox on average. Consult with an experienced and expert physician injector to ensure that the treatment would provide you sufficient benefit for the cost. (Kris M. Reddy, MD, FACS, West Palm Beach Plastic Surgeon)
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. (Trevor M. Born, MD, Toronto Plastic Surgeon)
Calculate How Much Botox Will Cost You
Treatment of forehead line with Botox
Every patient is different. 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. (Ronald Shelton, MD, Manhattan Dermatologic Surgeon)
I use 25-50 units
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. (Christopher L. Hess, MD, Fairfax Plastic Surgeon)
The amount of Botox required for forehead lines depends on the number of lines and how strong the forehead muscles are. I only inject small amounts of Botox into the forehead to prevent drooping of the eyebrows.
Horizontal Forehead Lines 8-16units
I always explain to patients that they may not totally get rid of the lines, but they will have a more natural result.
Fillers can also be injected into the lines to soften them. Please have treatment with an experienced physician injector. (Martie Gidon, MD, FRCPC, Toronto Dermatologist)
Botox Units for Horizontal Forehead Lines
This is an issue that really varies among different patients. The results of your BOTOX® injection depend on a lot of variables, including your existing skin tone, the strength of your forehead muscles, the depth of your wrinkles and how well your body responds to the treatment.
What I would recommend is consulting with an experienced surgeon who’s very familiar with the effects of BOTOX® to get the best results. You may also find even better results if you try combining the effects of BOTOX® along with injectable fillers to restore some of that lost volume that may also be contributing the deeper forehead wrinkles. (Joseph J. Castellano, MD, Tampa General Surgeon)
Botox to the horizontal forehead lines
The amount of Botox injected in the forehead lines will depend upon whether or not you want to completely” freeze” the frontalis muscle or just weaken it. The amount injected also depends upon how strong the muscle is, and how much deep wrinkles are present.
Most patients require 20-25 units injected in the frontalis muscle to soften the lines. (William Portuese, MD, Seattle Facial Plastic Surgeon)
Botox does work for horizontal lines on the forehead by relaxing the muscles that cause them. However, before you have that area injected, discuss your eyebrow position with your dermatologist. If your eyebrows are already drooping from age, you may rely on your forehead muscles to keep them elevated.
If the movement of the forehead is completely removed in that situation, your brows may flatten and give a ‘heavy’ look. If you are a candidate for botulinum toxin in the forehead, the number of units needed will be based on the size and shape of your forehead and strength of the muscles.
I use anywhere from 5 to 20 units of Botox or Xeomin or 10 to 40 units of Dysport. (Heidi A. Waldorf, MD, New York Dermatologist)
