doctors have been using botox off-label to improve the appearance of crow's feet for years.. but now the food and drug administration has officially approved that practice.
crow's feet are the tiny wrinkles that can pop up on the outer edges of eyes.
botox works by keeping muscles from tightening, so wrinkles are less prominent.
the f-d-a says two clinical trials established the safety and effectiveness of botox for crow's feet..
the most common side effect was swollen eyelids from excessive fluid.
