I am a 45 year old female and I have always hated my smile. My mouth downturns significantly while at rest and my smile goes almost completely horizontal when actively smiling. Which procedure would most effectively give me a pleasant, natural, upturned smile? Are there other muscles besides the DAO that would need to be addressed? I understand that botox is a great first step, but would the results from botox give me the same effect that surgery would accomplish?
