On September 11, the U.S. Food and Drug Administration (FDA) approved a use of Botox® Cosmetic (onabotulinumtoxinA) for the temporary improvement in the appearance of moderate to severe lateral canthal lines, which are more commonly referred to as "crow's feet." Physicians have used Botox® in this area for years "off-label," but the new FDA approval will offer consumers an additional level of confidence in the safety and efficacy of the product.
Botox® Cosmetic was first approved in 2002 for treatment of glabellar
lines (frown lines between the eyebrows).
The FDA has also stated that both frown lines and crow’s feet can be treated
at the same time.
The FDA approval is based on two clinical efficacy and safety studies:
“The studies
enrolled 833 adult participants with moderate to severe lateral canthal lines
who were randomly assigned to receive Botox or placebo. Results showed that
those treated with Botox had greater improvement compared to placebo in the
appearance of lateral canthal lines.
The most common
adverse reaction associated with the use of Botox Cosmetic for treatment of
lateral canthal lines is eyelid edema, a condition in which the eyelids are
swollen and contain excessive fluid.” (1)
Botox® is one of our most popular noninvasive
cosmetic procedures for both women and men.
It is a purified protein that works by blocking nerve impulses, allowing
muscles to relax, effectively eliminating wrinkles and giving the face a
rejuvenated look. Using a small needle,
tiny injections are made into the muscles that cause frown lines. Within
days you may see an improvement, but it can take two weeks to see the full
effect. Typically Botox® treatment lasts
three to four months.
Dermatology
Associates of Rochester is also a member of the Brilliant Distinctions®
Program, which is a program Allergan (the company who makes Botox®) created to
allow you to get exclusive offers on Botox® Cosmetic and their other products
including the cosmetic filler, Juvederm®.
