Dose of Beauty: How Many Units of Botox for Forehead?

Units of Botox for Forehead

BOTOX is one of the most popular cosmetic options for both men and women who’re seeking non-invasive treatment and prevention against wrinkles. It’s a flexible treatment that can easily be tailored to your specific needs, allowing you to achieve your cosmetic goals.

Among all the treatable areas of Botox, the forehead is the most commonly treated area, since the forehead is most easily affected by age and expressions, leading to fine lines and wrinkles.

Most people who’re planning to get forehead Botox wonder, “How many units of Botox for forehead?”.

In today’s blog, let’s find out the answer to this common query with Dr. Syra Hanif.

How Botox Works for Forehead Wrinkles?

Botox is injected into the forehead muscles to temporarily block the nerve signals that cause muscle contractions. By preventing these contractions, Botox relaxes the muscles, smoothing out forehead wrinkles that are caused due to repetitive facial expressions. Results typically become noticeable within a few days and can last for about 3-4 months before requiring another treatment session to maintain the effects.

How Many Units Of Botox For Forehead?

Botox usually comes in vials with doses ranging from 50 to 100 units. For forehead injections, practitioners might use around 10 to 30 units of Botox, but the manufacturer suggests 4 units per site, totaling 20 units.

Initially, your aesthetician might start with a lower dose to see how it works for you, then adjust the dose accordingly after 1 to 2 weeks. Generally, treatments are spaced 3 to 4 months apart, but initially, you might need a follow-up sooner, like after 2 to 3 months, until your practitioner figures out the right dosage for you.

How Long Does Botox Last?

Usually, Botox results last for about 4 months, but your first one might wear off faster. If that happens, you might need another one sooner. However, as you keep on getting Botox treatments, they should start lasting longer with each sessio.

Also, don’t worry if you don’t see the results right away – sometimes it takes up to 2 weeks for the results to get noticed, before deciding if you need another treatment.

How Does Botox Work On The Face?

Botox Cosmetic is approved by the FDA to treat lines on the forehead, lines between the eyebrows (often called “11” lines), and wrinkles around the eyes known as crow’s feet.

How Much Botox Can Be Used On The Forehead?

Doctors can inject between 15 to 30 units of Botox for horizontal forehead lines. For lines between the eyebrows (glabellar lines), up to 40 units are allowed, with higher doses sometimes needed for male patients.

Where Else on Face Can Botox Be Safely Injected?

Currently, Botox injections are approved by the FDA for crow’s feet around the eyes. Our expert aestheticians typically use 6 to 10 units per side for these lateral eye lines.
