Blepharoplasty (upper or lower eyelid surgery) is an operation to achieve a rejuvenated, more wide-awake look around the eyes. It can be performed on upper and/or lower eyelids.
As we get older, our skin loses some of its shape and tone. This loss of elasticity allows the skin around the eyes to sag and fat appears to bulge out. In the lower eyelid this causes bags and in the upper eyelid it manifests as a saggy, tired appearance.
