How Many Units Of Botox Will I Need?

Frown Lines (15-30 units)

Frown lines are caused when you repeatedly furrow your brow. They can make you look older than you actually are and they can give you a permanently grouchy look. The number of units used depends on the length of the wrinkle, but most people need between 15-30 units to treat frown lines. Frown lines begin between the eyebrows, extending both upward and downward, and sometimes even outward. Making a conscious effort not to frown will prove to be ineffective, as there is a tendency for people to frown in their sleep. Once the frown line is deep enough and is present even when your face is at rest, it will look like a deep “11” is engraved between your eyebrows, making you look angry, even if when you’re not.

Forehead Lines (4-12 units)

Continually raising your eyebrows results in the formation of a series of horizontal forehead lines. Over time, lines will form so that they are evident even when your forehead muscles are at rest. Neuromodulators are an effective solution for smoothing out these lines and wrinkles. The number of units needed to treat forehead lines varies from patient to patient and depend on how deep their lines are and how strong their muscles are. Typically however, 4-12 units are necessary to smooth this area out.

Crow’s Feet (6-15 units per side)

Crow’s feet are the lines on our faces that form when we squint and when we smile. Their formation are a natural part of aging and most people notice them in their mid-forties, although they may start showing up as early as age 20. 6-15 units injected on each side of the eye, will smooth this area out, and impart a fresher, younger appearance.

Eyebrows (2-6 units per side)

The frontalis muscle, located in the forehead, lifts the eyebrows up, while the corrugator muscles (between the eyebrows) and the orbicularis oculi (around the eyes) have the opposite effect, and pull the eyebrows down. By using a wrinkle relaxer on these muscles that pull the eyebrow down, the frontalis muscles is able to go unopposed, which serves to raise the eyebrows upwards, thereby creating a “brow lift”.

Bunny Lines (2-10 units per side)

When you smile or laugh, it causes the muscles on either side of your nose to be crinkled or “scrunched up”, leading to the formation of fines lines on either side of your upper nose, which are commonly referred to as “bunny lines”. The injection of a small number of units on either side of the nose will smooth out these wrinkles and also prevent or slow down the development of more bunny lines.

Lip Flip (2-4 units)

The “lip flip” is a very popular use of Botox. It involves the injection of neuromodulator into the muscle above the lip, which is called the orbicularis oris. The placement of the wrinkle relaxer in this area causes the lip to flip outwards slightly, which creates the illusion of a fuller or more prominent lip. This can be seen as a more subtle option than getting lip fillers.

Dimpled Chin (2-6 units per side)

The appearance of a dimpled chin is caused by excessive contraction of the muscle under the chin. Not only does this cause the chin to quiver, but it tends to make the texture of the chin look like an orange peel. 2-6 units of botox on each side of the chin is a simple remedy to this issue, leading to a smooth chin area.

Gummy Smile (2-6 units per side)

Some people have excessive gum display when they smile due to their facial anatomy. Botox is an effective solution to address this issue by relaxing the lip so that it won’t rise as high during a smile.

Corners of Mouth (2-6 units per side)

As part of aging, the area at the corners of the lips begin to sag, which results in wrinkles that extend downwards. These downward turning lines can sometimes make a person look like they are grimacing even when their face is at rest. A small amount of botox on each corner can help mitigate this downward movement.

Masseter (10-50 units per side)

Applying Botox to the masseter muscle, located on either side of the jaw, will help to relax this muscle, which has the effect of reducing its size. This will impart a slimmer, narrower and more feminine profile to the jaw. This is especially beneficial for women who have a square jawline, as an oval-shaped face or a heart-shaped face are widely considered to be the most desirable. In cases where a patient has an asymmetrical face, masseter Botox can also be used to restore symmetry to the face.

While this provides a general overview of the amount of botox a female patient under 40 can expect to need based on area of the face, like most things in medicine and aesthetics, there is no one-size-fits-all solution. The best way to determine how many units of Botox are needed for your specific concerns is to have a consultation with a qualified cosmetic injector. During the consultation, you will be examined and evaluated by the injector and they will recommend the appropriate amount of units that will give you the outcome you seek.
