Experiencing the under-eye area bulging outward while simultaneously appearing sunken is a particularly common concern for those in their mid-40s. Many cases involve confusion about the direction itself: "Should I remove fat or add it?" Below, I'll organize this step by step for you.


For those in Gangnam with under-eye fat bulging and sunken appearance in their mid-40s, which surgery is right for you?

When under-eye fat bulging and sunken appearance appear simultaneously in your mid-40s, the key is to first determine the degree of skin sagging before deciding whether to perform under-eye fat repositioning alone or in combination with lower blepharoplasty.

According to a Media Consumer News report, it is important to select a surgical method based on the current under-eye condition—elasticity, fat distribution, tear trough depth—rather than age. Rather than a simple "lower blepharoplasty because you're in your 40s" approach, if skin sagging is not severe and fat protrusion is the main cause, significant improvement can be expected from under-eye fat repositioning alone. On the other hand, if both fat protrusion and skin sagging are present together, combining lower blepharoplasty with under-eye fat repositioning is recommended.

One-line summary: The basis for choosing a surgical method is not age, but three current under-eye conditions: 'elasticity, fat, and tear trough.'


What is under-eye fat repositioning, and why is it effective in your 40s?

Under-eye fat repositioning is not a surgery to remove protruding orbital fat. The bulging fat is relocated to the sunken tear trough area below it to fill it in, creating an even under-eye line overall.

According to Medical Today, after the mid-40s, the orbicularis oculi muscle loses elasticity, causing the lower eyelid to sag and orbital fat to protrude forward. Simultaneously, the area below the tear trough becomes hollow and sunken. Because these two changes occur during the same period, "under-eye that appears both bulging and sunken" is created.

According to related clinical data, in cases where skin elasticity is significantly reduced, fat repositioning alone may have limitations. When the orbital septum is loosened, septum reinforcement and skin excision should be performed together to reduce the possibility of recurrence after surgery. This is why the presence or absence of remaining skin elasticity significantly influences final surgical satisfaction.


How 21plastic surgery approaches under-eye fat repositioning

A case with simultaneous under-eye bulging and sunken appearance does not end with simply relocating fat. You must integrate fat redistribution direction, orbital septum reinforcement, and whether to combine with aegyo-fat grafting from the start to expect natural under-eye lines.

21plastic surgery designs under-eye fat repositioning and aegyo-fat grafting together tailored to each individual's under-eye structure. Based on its convenient location between Sinnonhyeon Station and Gangnam Station, it systematically addresses under-eye concerns of diverse domestic and international patients.

The main items confirmed during the diagnostic process are as follows.

— Identifying orbital fat protrusion location and volume distribution
— Measuring tear trough depth and sunken area extent
— Evaluating under-eye skin elasticity and remaining thickness
— Confirming orbital septum laxity
— Determining whether to combine aegyo-fat grafting
— Designing final surgical plan considering overall facial balance

Diagnosis is structured not merely to decide on single procedure options, but to consider overall facial balance as well.


Be cautious in these cases—pre-operative self-check list

Under-eye surgery in your mid-40s varies depending on the degree of skin sagging, orbital septum laxity, and tear trough depth. If any of the items below apply to you, be sure to inform your surgeon before surgery.

Items affecting surgical direction decision

— When you gently tug the under-eye skin, almost no elasticity is felt
— Tear trough appears deeply sunken along with bulging
— Dark circles are appearing along with fat protrusion
— Overall under-eye or eye corner skin appears sagging

Health items that must be disclosed before surgery

— You have chronic conditions such as hypertension or diabetes
— You are taking anticoagulants (aspirin, warfarin, etc.) or blood circulation improvement medications
— You have severe dry eye or underlying eye-related conditions
— You have keloid-prone skin or slow scar healing

According to Cashdoc medical information, swelling and bruising after surgery typically improve within 1-2 weeks, but 2-3 months are required to confirm final results. It is recommended to plan your recovery schedule with ample time.

Those considering under-eye fat repositioning in Sinnonhyeon, eye plastic surgery in Nonhyeon-dong, or under-eye plastic surgery at Gangnam Station can also begin consultation based on the same checklist.


If you're curious about the right direction for you, confirm it through consultation

If you're curious about the right direction for you, visit 21plastic surgery located between Sinnonhyeon Station and Gangnam Station for a consultation.

As Media Consumer News emphasizes, under-eye fat distribution, degree of skin sagging, and tear trough depth vary from individual to individual, so customized treatment should be applied rather than standardized surgical methods. Complex under-eye concerns that "seem both bulging and sunken" are most accurately confirmed through direct diagnosis. Through one-on-one consultation with a board-certified plastic surgeon, you can confirm a specific direction suitable for your current under-eye condition.


Frequently asked questions

Q1. I'm in my mid-40s—is under-eye fat repositioning alone sufficient, or do I also need lower blepharoplasty?

If skin sagging is not severe and fat protrusion is the main cause, improvement can be expected from under-eye fat repositioning alone. However, if skin sagging is present, you should consider whether to combine it with lower blepharoplasty. Age is less important than your current under-eye elasticity and sagging degree as the basis for judgment.

Q2. How long does it take for results to appear after under-eye fat repositioning?

Swelling and bruising typically improve within 1-2 weeks, but 2-3 months are usually needed for under-eye tissue to fully stabilize and confirm final results. It's best not to judge results based only on initial swelling.

Q3. When under-eye bulging and sunken appearance occur simultaneously, is combining aegyo-fat grafting helpful?

Even if fat repositioning fills the tear trough area, if the aegyo region lacks volume, the overall under-eye line may appear uneven. Whether to combine aegyo-fat grafting should be decided after directly examining the under-eye structure and volume distribution.

Q4. How long do swelling and bruising last after under-eye fat repositioning?

Although it varies by individual constitution, swelling and bruising typically noticeably decrease within 1-2 weeks. If you are taking anticoagulants or have underlying blood circulation-related conditions, the recovery period may differ, so be sure to disclose this to your surgical team before surgery.

Q5. Is there no possibility of recurrence after surgery? Why is orbital septum reinforcement important?

If fat is only repositioned when the orbital septum is loose, there is a possibility that the fat may protrude forward again over time. Performing septum reinforcement together helps the repositioned fat remain in place and plays an important role in maintaining long-term results.
