Upper and lower blepharoplasty are two distinct surgical procedures that reshape the eyelids by removing or repositioning excess skin, muscle, and fat. Upper blepharoplasty targets the area between the eyebrow and the eyelash line, while lower blepharoplasty addresses the under-eye region, including bags and hollowing. Both can be performed for cosmetic reasons, but upper blepharoplasty is also commonly done as a functional procedure when drooping skin blocks your peripheral vision.
What Upper Blepharoplasty Corrects
Upper blepharoplasty treats a condition called dermatochalasis, which is the medical term for excess, sagging skin on the upper eyelid. It’s one of the most common age-related changes around the eyes. Over time, the skin of the upper eyelid (which is already among the thinnest on the body, at roughly 850 microns) loses its elasticity. The result is heavy, drooping folds that can make you look tired or older than you are.
In more advanced cases, the overhanging skin actually pushes down on the eyelashes and obstructs the upper portion of your visual field. This is called lash ptosis, where the weight of the excess skin causes the lash follicles to point downward. When drooping reaches the point where it interferes with your line of sight, the procedure crosses from cosmetic into functional territory, and many insurance plans will cover it. Getting that coverage typically requires visual field testing that shows improvement when the eyelid is manually lifted, along with photographic documentation of the skin excess.
How Upper Eyelid Surgery Works
The incision is placed directly in the natural crease of the upper eyelid, which means the scar becomes virtually invisible once it heals. The surgeon marks the amount of skin to be removed before making any cuts, with the incision line angled slightly upward toward the outer corner for a natural-looking result.
After the skin is removed, a variable amount of the underlying muscle may also be trimmed, depending on how much bulk is present. The surgeon then opens the orbital septum, which is the thin membrane that holds back the fat behind your eyelid. The upper eyelid contains two fat pads (a medial one closer to the nose and a central one), and the surgeon removes only as much fat as needed. Taking too much creates a hollow, sunken appearance. A critical safety margin applies throughout: at least 10 millimeters of skin must be preserved between the brow and the incision line to ensure the eyelid can still close fully after surgery.
What Lower Blepharoplasty Corrects
Lower blepharoplasty targets the puffiness, bags, and loose skin beneath the eyes. The “bags” most people notice are caused by fat pads that push forward as the membrane holding them weakens with age. At the same time, the transition zone between the lower eyelid and the cheek (the tear trough) can deepen, creating a shadowed, hollow look that makes the bags appear even more prominent.
How Lower Eyelid Surgery Works
There are two main approaches, and the choice depends on what needs to be corrected. A transcutaneous approach places the incision just below the lash line on the outside of the eyelid. This gives the surgeon access to remove excess skin and muscle in addition to managing fat. A transconjunctival approach places the incision on the inside of the eyelid, leaving no visible scar at all. This route works best for younger patients who have fat bulging but minimal loose skin.
The way surgeons handle the fat itself has evolved significantly. Older techniques involved simply cutting away the protruding fat pads, but this often left patients with a hollowed-out look and could actually worsen the tear trough depression. Modern lower blepharoplasty favors fat repositioning instead: the three lower eyelid fat pads (medial, central, and lateral) are kept attached to their blood supply and moved downward over the rim of the eye socket to fill in the hollow tear trough area. This creates a smooth, natural contour between the lower eyelid and the cheek rather than a sharp transition.
Combining Upper and Lower Surgery
When both the upper and lower eyelids show significant aging, many surgeons recommend treating all four lids in a single operation, sometimes called a quad blepharoplasty. The advantage is a balanced result. Correcting only the upper lids, for example, can make under-eye bags more noticeable by contrast. Combining procedures also means one recovery period instead of two.
The surgery is typically performed under local anesthesia with sedation, though general anesthesia is sometimes used for combined procedures. The upper eyelid incisions hide in the natural crease, while the lower eyelid incisions sit either just below the lash line or inside the lid itself.
Recovery Timeline
Swelling and bruising peak around 48 to 72 hours after surgery. Cold compresses and keeping your head elevated help during this initial phase, and antibiotic ointment is applied to the incision sites and eyes to prevent dryness and corneal irritation. If non-absorbable stitches were used, they come out at 5 to 7 days.
Most people return to desk work and light daily activities within 7 to 10 days. Bruising may linger for about two weeks but is easily concealed with sunglasses or light makeup once the incisions have closed. Strenuous exercise, heavy lifting, and anything that raises blood pressure to the face should be avoided for several weeks to reduce the risk of bleeding or prolonged swelling.
How Long Results Last
Upper blepharoplasty results typically last five to seven years, and in some patients last a lifetime, depending on genetics, skin quality, and how much the remaining tissue continues to age. Lower blepharoplasty is more durable. According to Cleveland Clinic, lower eyelid surgery rarely needs to be repeated. The fat repositioning done during lower blepharoplasty tends to be especially long-lasting because the tissue is moved to a new structural position rather than simply tightened.
Risks and Complications
The most common issue in the early postoperative period is temporary dry eye. Most patients experience some degree of difficulty fully closing the eyelids right after surgery due to swelling and stiffness, which can dry out the surface of the eye. For people who already have dry eyes, or who have had LASIK or similar refractive surgery, this risk is higher. Surgeons typically screen for these issues beforehand with tear production tests.
The complication specific to upper blepharoplasty is lagophthalmos, which is the inability to fully close the upper eyelid. This happens when too much skin is removed, leaving less than the critical 10-millimeter margin. Mild cases (1 to 2 millimeters) can sometimes be corrected by elevating the lower lid. More severe cases may require additional surgery.
For lower blepharoplasty, the primary concern is ectropion, where the lower eyelid pulls away from the eye and turns outward. This can result from removing too much skin, scarring of the deeper tissue layers, or underestimating the natural looseness of the eyelid. If caught early, revision surgery is relatively straightforward. More established cases may require skin grafting to restore enough tissue to let the lid sit in its normal position.
Pre-Surgery Evaluation
Before blepharoplasty, your surgeon will examine the tear film and corneal surface, check for any existing dryness, and test whether your eyelids close completely. If you have dry eye symptoms, those need to be managed with artificial tears or other treatments before surgery to reduce the risk of corneal problems afterward. The exam also assesses how much fat is present, whether the eyelid’s lifting muscle is functioning normally, and whether the issue is truly excess eyelid skin or a drooping brow that’s pushing tissue onto the lid from above. Misdiagnosing a low brow as eyelid excess leads to underwhelming results and can worsen the appearance.
