Maybe you know the basics about Botox injections, that they’re designed to smooth wrinkles by paralyzing facial muscles. But do you know what areas Botox treats? Or how many units of Botox you need for your forehead? Do you know how long it takes for Botox to work? Check out our illustrated Botox forehead and face guide to get some quick answers before you go under the needle.
Botox has been approved by the FDA to smooth moderate to severe wrinkles on three areas: the crow’s-feet by the eyes (lateral canthal lines), frown lines between the eyebrows (glabellar lines), and forehead lines.
Providers inject three spots around each eye, five spots between the eyebrows, and five spots across the forehead.
Note: The Botox forehead and face treatment areas listed above are FDA- and manufacturer-approved areas for injection. Some doctors will use Botox "off-label," which means injecting an area that isn't officially approved for injections. For instance, they might use Botox to raise the nasal tip for a faux rhinoplasty.
Note: Forehead and frown lines are typically treated together, requiring a total of 40 units.
Remember, these are general guidelines. Doctors may need to inject more units to treat deeper lines or tougher skin. Women generally need fewer units than men. A consultation with your doctor will tell you exactly how many units of Botox you need to achieve your desired result.
Botox face injections start working fairly quickly, and patients can typically see results in 24–48 hours. Optimal results are generally seen after 30 days and results last about three to four months.
Information on injection sites, recommended number of units, and expected results comes from the manufacturer's website. Botox may cause serious side effects that can be life threatening. Read all of the safety considerations for Botox here.
