Sub-Brow Incision (Brow Lift) — A Way to Naturally Improve Upper-Eyelid Sagging

"My eyelids feel heavy lately... but I don't want to end up with a face that obviously looks operated on!" — for you who feel that way.

[What you'll learn in this article]

• The real cause of your "heavy eyelids"
• "Sub-brow incision" and the decisive difference in result from a "double-eyelid incision"
• Why the scar of a sub-brow incision is hard to notice and hard for others to detect
• The duration of effect and downtime based on medical data
• The anatomical grounds of the "natural result" that specialists insist on

Now in your 30s to 50s, do you feel that "my double-eyelid width seems narrower than before" or "by evening my eyelids are heavy and I unconsciously raise my eyebrows"? Many people, while noticing the changes in their eyes, hold the anxiety that "if I have incision surgery, my eyes might look unnatural, as if I obviously had work done...."

In fact, there is a refined option that resolves only the heavy sagging cleanly without changing the original natural impression of the eyes, called"sub-brow incision (browlift: infraeyebrow blepharoplasty)."In this article, Zetith Beauty Clinic, based on the latest medical knowledge, thoroughly explains the secret of the sub-brow incision that achieves natural rejuvenation.

Wait, isn't the double-eyelid width narrowing because "the double eyelid disappeared"? (the indication for sub-brow incision)

We often hear the worry that "I used to have wide double eyelids, but lately they've become like inner double eyelids." But this does not mean the double-eyelid line itself has disappeared. Its fundamental cause lies in"upper-eyelid dermatochalasis (a state in which the skin of the upper eyelid has stretched and drooped due to aging and so on)."Asian eyelids have a structure with thicker skin and subcutaneous tissue than Westerners' (

Lu et al.). The thick skin that has lost elasticity with aging cannot resist gravity and droops, covering over the original double-eyelid line, so the double-eyelid width looks narrow or the eyelid feels heavy. Unlike "eyelid ptosis," in which the muscle that opens the eye itself has weakened, the majority of cases have excess skin (sagging) as the main player.[Characteristics of those suited to a sub-brow incision]

People who originally have double eyelids (or inner double eyelids) and like their natural shape

• People who have the strength to open their eyes but whose eyelids are heavy because of the covering skin
• People who are especially concerned about sagging on the outer side of the eyelid (the outer-corner side)
• By contrast, in the case of those who originally have single eyelids and want to "newly create a double-eyelid line," or those with little skin sagging itself, a double-eyelid incision (or the buried-suture method) is indicated. Discerning whether your worry is "sagging" or "the double-eyelid line itself" is the first step toward a natural result.

Avoid an "obviously operated-on face"! The decisive difference between a sub-brow incision and a double-eyelid incision

Surgery to remove eyelid sagging mainly has two types: "sub-brow incision" and "double-eyelid incision (excising skin on the double-eyelid line)." There is a clear reason why we recommend the sub-brow incision for our target readers.

Human eyelid skin has the characteristic of being

thicker the closer to the eyebrow, and thinner the closer to the eyelashes. If you try to remove sagging with a double-eyelid incision, you end up cutting away the "thin, supple skin" on the eyelash side, and as a result the "thick skin" on the eyebrow side descends to the fold of the double eyelid. As a result, the crease of the double eyelid becomes too strong, or the puffy, unnatural operated look called "ham eye" tends to appear.Chen et al.also point out in their report that, if the orbicularis oculi muscle is excessively excised or a strong adhesion is created during a double-eyelid incision, the flexibility of the eyelid is lost, tending to form an unnatural, stiff expression.On the other hand, a sub-brow incision is surgery that excises and lifts the "thick skin" just below the eyebrow. Because the thin, natural skin on the eyelash side is preserved as is, the result is so natural that you cannot tell surgery was done.

"Won't putting a scalpel to my face be noticed?" The advantage of the scar hidden in the sub-brow line

It is natural to worry, "cutting a conspicuous part of the face, won't the scar remain for life?" But there are solid anatomical grounds for why the scar of a sub-brow incision becomes surprisingly inconspicuous.

First, because the incision line is set along the lower edge of the eyebrow (the very line where the hair grows), the scar hides in the shadow of the eyebrow. Furthermore, the outer region of the upper eyelid (the outer-corner side) has a sparse distribution of blood vessels, so bleeding and strong postoperative inflammation are unlikely, and the healing of the wound proceeds relatively smoothly — this is a characteristic (

Lu et al.). At our clinic, by using a special incision method that preserves the hair follicles (the roots of the hair) and a precise suture technique that releases the tension on the skin (the pulling force) with internal sutures, we finish the scar as thin as possible.[The course of the postoperative scar (timeline)]

1 week after surgery (at suture removal):

• There is redness, and the sutures are attached (can be camouflaged with thick-framed glasses, etc.).1 month after surgery:
• It is the peak of redness and hardness, but at a level that can be sufficiently hidden with makeup (eyebrow makeup).3 to 6 months after surgery:
• The redness subsides and it changes into a thin, white line.1 year after surgery:
• It blends with the contour of the eyebrow and settles into a state where it is almost invisible even without makeup.To heal the scar beautifully, scar care such as UV protection and sufficient moisturizing after surgery is very important. The clinic also introduces dedicated care products and supports you until complete healing.

Lifelong rejuvenation? Data on the duration of effect and the "real downtime"

In aesthetic medicine, "how long does the effect last?" and "how long should I rest?" are points everyone wants to know.

The excess skin physically excised by a sub-brow incision will never return to its original state. Of course, the natural aging process continues after surgery as well, but because you start over from a state with the hands of the clock turned back several years to 10 years,

you can maintain youthful eyes over the long term.
According to recent research (Okumura et al.), it has been proven that by appropriately handling and removing excess fat of the upper eyelid (orbital fat or ROOF: sub-orbicularis oculi fat), the stability of the postoperative double-eyelid line improves over the long term, and the risk of sagging recurring and requiring reoperation is significantly lowered. At our clinic, too, we pursue a lifelong beautiful result by combining the optimal fat treatment according to the thickness of the eyelid.[Typical downtime]

Compared with a double-eyelid incision, the downtime of a sub-brow incision is surprisingly mild.

Swelling and bruising:

• The day after surgery to day 3 is the peak. Major swelling subsides in about 1 to 2 weeks. Because the double-eyelid line is not touched, you do not get the unnatural way of swelling like Gachapin.Return to daily life:
• From the next day, you can shower from the neck down. From the day after suture removal (about 1 week after surgery), eye makeup is possible, and many people also return to work at this timing.A specialist explains! The anatomical mechanism that supports a "natural result"

Why can a sub-brow incision remove only the sagging without changing the impression of the eyes? This is related to the delicate anatomical structure of the eyelid.

The eyelid has a layered structure of, in order from the surface, "skin" → "orbicularis oculi muscle (the muscle for opening and closing the eye)" → "orbital septum (the membrane that wraps the fat)." In Asian eyelids these tissues are thick, with a characteristic heaviness.

According to a study byYang et al., the formation of a natural double eyelid is deeply involved with a structure called "septoaponeurosis junctional thickening (SAJT)," which, in conjunction with the skin, creates a dynamic, smooth double-eyelid fold.

The greatest advantage of a sub-brow incisionis that it does not touch this delicate mechanism of double-eyelid formation (the structure of the eyelid margin) at all. Because the complex structure on the eyelash side is preserved as is and only the unnecessary upper "resistance layer (thick skin and muscle)" is removed, the natural double-eyelid line you originally had revives as is, with the obstructing skin gone.

Also, to not change the position and shape of the eyebrow, meticulous calculation of the excision design is indispensable. Rather than just cutting skin, predicting even the pulling of the muscle and the postoperative drooping of the eyebrow (the phenomenon in which, by removing the sagging, the unconscious raising of the eyebrow ceases and the eyebrow drops) and adjusting the amount of excision in millimeter units is precisely where a specialist's skill shows.
