A Third Eyelid Crease Appeared One Day: What to Check Before Eye-area Filler

Some mornings, you may look in the mirror and notice an extra line above your usual eyelid crease.
On one day there may be one crease, while on another the eyelid appears to have an additional fold.
In the consultation room, I often hear, “Would eyelid-crease filler help?”
“Eye-area filler” is a general term for treatments such as outer-corner, cat-eye, eyelid-crease, under-eye, and aegyo-sal filler that use hyaluronic acid filler around the eyes to adjust their appearance. Although the names may sound similar, each treatment targets a different location and concern.
Why might an extra eyelid crease suddenly appear?
The main possible reasons include loss of upper-eyelid volume, skin laxity, reduced strength in opening the eyelid, and a history of eye surgery.
The cause affects where filler might be placed, how much might be used, and whether filler is appropriate at all. That is why I assess the cause before focusing on the treatment name.
What is checked in the upper eyelid before eyelid-crease filler?
First, I assess whether the upper eyelid is genuinely hollow.
If hollowness is present, the whole hollow area needs to be considered, rather than only the site of the extra crease.
If marked skin laxity or difficulty opening the eyelid is the issue, the cause should be assessed before adding volume.
Please let your clinician know if you have had double-eyelid surgery or eyelid fat removal.
Do outer-corner filler and cat-eye filler actually make the eyes longer?
Outer-corner and cat-eye filler do not lengthen the eye by making an incision at its outer corner, as lateral canthoplasty does.
A more accurate understanding is that, where there is hollowness around the outer corner or an interrupted contour between the temple and eye area, replacing volume may change how the outer eye area appears.
For a cat-eye filler consultation, I assess the outer-corner angle, the position of the eyebrow tail, and temple hollowness together.
| Treatment | Main area assessed | Common concern | What to distinguish before filler |
| Eyelid-crease filler | Upper eyelid | Multiple eyelid creases | Skin laxity, eyelid-opening strength, and surgery history |
| Outer-corner filler | Outside the outer eye corner | The eye appears short | Actual eye length versus hollowness around it |
| Cat-eye filler | The connection between the outer corner and temple | The eye area appears downturned | Outer-corner angle and eyebrow-tail position |
| Under-eye filler | Tear trough | A shadowed, tired appearance | Pigmentation, visible vessels, and under-eye fat bulging |
| Aegyo-sal filler | Lower eyelid | The contour just beneath the eye looks less defined | Whether under-eye fat is being mistaken for aegyo-sal |
Will combining under-eye filler and aegyo-sal filler make my eyes look more defined?
Combining these two treatments does not necessarily create a more defined eye appearance.
People with thin skin and little facial soft tissue may notice a large change from a small amount, while adding more volume where enough is already present may look less natural.
With aegyo-sal filler, placement and thickness matter more than the amount alone, so I assess the area both when smiling and at rest.
With under-eye filler, I also assess whether the contour from beneath the eye to the front of the cheek is smooth and natural.
When might another assessment be needed before eye-area filler?
Another assessment may take priority when under-eye fat bulging is pronounced, swelling recurs, or skin laxity is the main issue.
If previous filler remains, its location also needs to be checked.
The skin around the eyes is thin and the vascular anatomy is complex. Superficially placed filler may appear bluish. Bruising, swelling, or unevenness can occur after treatment, and vascular complications have also been reported rarely.
Frequently asked questions
Q. Can an extra eyelid crease appear and then return to the usual crease pattern?
An extra fold can sometimes appear temporarily with swelling or changes in your condition, then settle again. If the change keeps recurring or becomes more frequent, it can help to have the upper-eyelid volume and skin assessed.
Q. Does filler around the eyes disappear over time?
Hyaluronic acid filler is absorbed over time, but it may remain longer than expected around the eyes. A dissolving enzyme may be used when needed; a clinician assesses the condition before deciding whether this is appropriate.
Q. What should I tell the clinician at an eye-area filler consultation?
You do not need to arrive with a treatment name in mind. It is enough to explain what about your eye appearance you would like to change. Sharing any history of surgery or filler also helps the assessment.
Consider a consultation if:
· Your eyelid crease changes frequently and extra folds keep recurring
· Opening your eyes feels heavier than it used to
· An area previously treated with filler looks uneven or bluish
At a glance
An extra eyelid crease can have several causes, including upper-eyelid volume loss, skin laxity, reduced eyelid-opening strength, and previous surgery. The cause should be assessed before eye-area filler. Outer-corner and cat-eye filler change the surrounding volume rather than lengthening the eye. If fat bulging or skin laxity is the main issue, another assessment may take priority.
In summary
A sudden extra eyelid crease can result from upper-eyelid volume loss, skin laxity, reduced eyelid-opening strength, or previous eyelid surgery, so the cause should be identified first.
