The goal of lower blepharoplasty is not “flatness”

One of the most common misconceptions about lower blepharoplasty is the idea that the smoother and flatter the area under the eyes looks, the younger it appears.

But in many real failure cases, the problem is not what was done, but what was removed too much.

Brow fat is not simply fat

Brow fat is often mistaken for unnecessary fat, but in reality it is a functional structure closely connected to the orbicularis oculi muscle and moves with changes in facial expression.

It has a major effect not only when the eyes are open at rest, but also on the impression and natural look when smiling.

If this structure is removed or flattened indiscriminately, the result can instead look unnatural and older.

Symmetry is different from balance

Many patients want perfect left-right symmetry.

But facial muscles are not naturally completely symmetrical.

The way we smile, muscle strength, and supporting structures can differ between the left and right sides.

If you try to force these differences into alignment through surgery, it can leave a stiff impression instead of a natural one.

The goal of lower blepharoplasty is not perfect symmetry, but balance.

What happens when brow fat disappears

When brow fat is removed or made overly flat

  • the natural curve of the lower eyelid disappears

  • the expression looks stiff

  • even after surgery, the eyes may look tired or hollow

This may be the result of overcorrection, not rejuvenation.

Preservation does not mean a less thorough surgery

Preserving brow fat does not mean doing less surgery.

It is about accurately judging how far to adjust and what should be left alone.

You have to consider muscle movement, the position of fat, skin elasticity, and long-term stability.

In lower blepharoplasty, a more difficult skill than excision is the judgment not to excise.

Preserving your own brow fat is the most natural surgical method.

Ahnsungmin Plastic Surgery’s perspective

We do not aim to eliminate every contour under the eyes.

Natural expression, structural support, and long-term stability that does not lead to revision surgery are the standards for lower blepharoplasty.

Lower blepharoplasty should be judged based on a moving face, not a still photograph.
