Adding a filler such as radiesse to the corners of the mouth can really change a sad or angry looking mouth into a happy one for roughly $650/syringe and lasts about a yr. Sincerely, David Hansen,MD
As the aging process progresses, downturned corners of the mouth inevitably occur. This can be improved non-surgically using dermal fillers and botox. Please consult with a board certified specialist who can assist you with improving this area of concern.
