Botox treatments are an investment in you. Scheduling the proper amount of time between visits will help ensure that you’re always looking your best. If you find yourself asking, “How long does Botox last,” the answer lies in what area of the face you’re focusing on and the dosage used in that area.


The forehead is the most common area where patients request Botox injections. Typically, your dosage will range between 10-15 units, depending on how natural you want your results to be.

Because the prescribed dosage for this area can be high, results can last anywhere from 3-6 months. Additional variables such as age and metabolism can impact the duration of the Botox effect.

Crow’s Feet

Botox is the most commonly used solution in the battle against crow’s feet. Once injected, you’ll start to notice that the muscles around your eyes relax and resist crinkling when you smile or laugh.

Crow’s feet require anywhere from 5-12 units per eye in order to be effective. You can expect results to last around 4 months, but don’t be surprised if you notice a long term decrease in wrinkles. The relaxation of those muscles allows them to weaken and resist movement even between treatments.


If you’re looking to lift the brow area, Botox can help without going under the knife. Only 2-5 units of Botox are needed for each brow, making this one of the most affordable treatments you can get for a younger looking visage. Unfortunately, that low dose can also mean less time between treatments.

Glabella or Frown Lines

Also referred to as the “number 11s,” more units may be necessary to obtain the desired look in this area, usually 20-25 units. Treatments for eyebrow furrows can last anywhere from 2-6 months.

As always, when you are considering cosmetic procedures seek out Board-Certified providers, such as the Dermatologists at Advanced Dermatology & Cosmetic Institute.
