Botox blocks nerve impulses, which in turn forces certain key muscles to relax. When the muscles that cause wrinkles are forced to relax, the wrinkles above those muscles will also relax. Botox also prevents the wrinkles from forming again, because it's more difficult to move the muscles causing them.
Botox treats the type of wrinkles that are created by motion. These wrinkles, known as dynamic wrinkles, typically appear in areas like the forehead, between the eyebrows, and next to the eyes (crow's feet.) The other type of wrinkle, that which is caused by depletion of collagen and elastin, can't be treated by Botox but is ideal for dermal filler treatment. Botox and dermal fillers can be combined to eliminate both dynamic and static wrinkles in the face.
It may take up to 7-10 days to see results from Botox treatment. Many patients have visible results before that time, however.
The effects of Botox can last for up to 4 months. Patients who receive Botox on a regular basis get the most longevity from their Botox treatments.
No injectable anesthesia is needed for Botox treatments. A cold pack is used to minimize discomfort, pain, and swelling. If the patient is very sensitive, a topical anesthetic may also be used.
Botox is an outpatient treatment that is performed in just 10-15 minutes. This treatment is easily scheduled on a lunch break, as the patient can go right back to their job or regular routine immediately.
After Botox treatment, patients should avoid sun exposure (including tanning beds) and should not lay flat for 4 hours after the treatment. Patients should also avoid bending over for at least 4 hours to avoid movement of the Botox. Blood thinner medications should be avoided, as this can cause bruising. Any direct pressure on the treatment area should be avoided, as well.
