With age, a decrease in collagen and elastin production can lead to excess or "sagging" eyelid skin, a condition known as blepharoplasty. Fat can also seep into the thin tissue of the upper eyelid due to the weakening of the connective fibers, causing sagging and drooping of the skin.
Blepharochalasis can also result from eyebrow drooping, which requires lifting to correct it. Identifying the cause of eyelid drooping is important for the plastic surgeon to choose the appropriate surgical design. Your surgeon will also evaluate your dry eye, as this may require modifications to the procedure and post-operative care.
The lower eyelids also undergo changes with age. The skin in this area becomes thinner over time and the soft tissues under the eyes descend, creating unsightly bags under the eyes.
