The U.S. Food and Drug Administration today approved a new use for Botox Cosmetic (onabotulinumtoxinA) for the temporary improvement in the appearance of moderate to severe lateral canthal lines, known as crow’s feet, in adults. Botox Cosmetic is the only FDA approved drug treatment option for lateral canthal lines.

The FDA approved Botox Cosmetic in 2002 for the temporary improvement of glabellar lines (wrinkles between the eyebrows, known as frown lines), in adults. Botox Cosmetic works by keeping muscles from tightening so wrinkles are less prominent.

“This additional indication will provide people with a new FDA approved treatment option for those seeking a smoother appearance by temporarily minimizing the appearance of crow’s feet at the sides of the eyes,” said Susan Walker, M.D., director of the Division of Dermatology and Dental Products in the FDA’s Center for Drug Evaluation and Research.

Botox Cosmetic is administered via intramuscular injections. Treatment for both frown lines and crow’s feet can be given at the same time.
