Why Aegyo-Sal Should Be Preserved in Lower Eyelid Surgery.

The Goal Is Not a Flat Lower Eyelid.

One of the most common misunderstandings in lower eyelid surgery is the belief that a smoother, flatter under-eye area always looks younger.

It does not.

In many failed lower eyelid surgeries, the problem is not what was done—but what was removed.

Aegyo-Sal Is Not Just Fat.

Aegyo-sal is often misunderstood as excess fat under the eye.
In reality, it is closely related to the orbicularis oculi muscle and the dynamic movement of facial expression.

This structure plays a critical role in how the eye looks at rest and, more importantly, how it looks when smiling.

Removing or flattening this area indiscriminately leads to an unnatural and aged appearance.

Symmetry Is Not the Same as Balance.

Many patients request perfectly symmetrical lower eyelids.

However, facial muscles are rarely symmetrical.
Differences in smiling patterns, muscle strength, and support structures are normal.

Attempting to erase these differences surgically often results in stiffness rather than harmony.

Lower eyelid surgery should aim for balance—not forced symmetry.

What Happens When Aegyo-Sal Is Lost.

When the aegyo-sal is removed or overly flattened:

  • The lower eyelid loses its natural contour

  • Facial expressions appear rigid

  • The eyes can look tired or hollow despite surgery

This is not rejuvenation.
It is overcorrection.

Preservation Requires Judgment.

Preserving aegyo-sal does not mean doing less surgery.
It means understanding which structures must remain untouched.

This requires careful evaluation of muscle movement, fat position, skin elasticity, and long-term stability.

In lower eyelid surgery, restraint is often the most advanced technique.

The Perspective at Ahnsungmin Plastic Surgery.

Our goal is not to erase every contour under the eye.

It is to preserve natural expression, maintain structural support, and prevent long-term complications that lead to revision surgery.

Lower eyelid surgery should respect how the face moves—not just how it looks in a still image.
