Neuromodulators are chemical substances that affect signal transmission in nerve cells. The most commonly used are Botulinum toxin A (BTA), commonly known as BOTOX®, Dysport®, and Xeomin®.
Once the drug is injected into the skin, it produces a temporary weakness of the muscles by preventing the transmission of nerve impulses to the muscle. The medication can be used to treat wrinkles in the forehead and eyelids, or to prevent the formation of deep lines. Dr Farhang Khoee customizes injections for each patient, depending on his or her needs. The drug takes a few days to start taking affect and will be fully working within two weeks. The duration of muscle weakness lasts approximately three to four months.

An ideal candidate is a person in good health and requesting a neuromodulator for the following reasons:

• Wrinkles in the upper portion of the face, including the forehead or around the eyes such as crow’s feet
• Vertical lines near the nose that arise from crinkling the nose
• Wrinkling around the mouth including peri-oral lines and frown lines

In general, there is no residual pain after the treatment and no recovery time. Some redness, swelling and minor bruising can occur at the injection site, but recovery time is minimal, lasting only a few hours.
