The phenomenon that you are describing - wrinkling beneath the eyes that is exacerbated with smiling - is a common concern. These under eye wrinkles will often become more pronounced following Botox injections to treat crow's feet. Minute amounts of Botox carefully injected may help to mitigate these wrinkles. However, too much Botox in this area can weaken important muscles around the eye and may lead to dryness or inability to properly close the eye. So, your doctor is correct to be cautious. Be sure to go to a very experienced injector if you choose to have this area treated.
