Botox®
This is one of the most popular procedures done. With our comprehensive knowledge about the muscles and nerves of the face, we can utilize Botox to not only eliminate wrinkles, but also to refresh the eyes and eyebrow. Botox is also used to eliminate the neck bands that commonly develop as we age. Also, Botox can be used to reduce the fines lines commonly seen around the mouth.
In some patients with Migraine headaches, Botox has been able to eliminate or significantly reduce the symptoms entirely. Botox can also eliminate excessive sweating of the palms, feet, and axilla (armpits), with relief lasting up to 1 year.

Treatment of wrinkles should last upwards of 3 months. Treatment of excessive sweating can last up to 1 year.
No. It generally takes 2-5 days for the effect of the injections to be seen.
Technically Botox is a bacterial toxin that when injested in high doses can cause serious illness. However, the Botox that is used for cosmetic purposes is a highly purified form and is used in microscopic doses administered into very specific muscles. It only acts to temporalily paralyze the muscle it is injected into, and has no systemic effects.
Wrinkles are a result of long-standing muscle contractions. As the muscles continuously contract, the skin becomes "squeezed" and will form a line or indentation (a wrinkle). This is most commonly seen between the eyebrows when we squint our eyes. Deep lines often need a filler material to eliminate or reduce them. It makes sense that paralyzing strong or overactive facial muscles may prevent these wrinkles from forming later in life.
