Early Double Eyelid Revision
Can multiple upper eyelid creases also be corrected early?
Dr. Dongil ChoiIn many cases, yes. The existing crease is reopened to release the incorrect adhesions, so no new incision is needed. However, the goal is not to refine the crease but to eliminate the discomfort caused by the multiple upper eyelid creases.

Early Double Eyelid Revision
How can I tell whether it is just swelling or the surgery went wrong?
Dr. Dongil ChoiRight after surgery, swelling often makes the crease look thick or asymmetric, so it is difficult to judge on your own. Since 1-2 weeks is the best time for early correction, if you are concerned, we recommend getting a diagnosis from a board-certified plastic surgeon promptly rather than waiting.

Shurink
What is the difference between Shurink and Ultherapy?
Dr. Dongil ChoiBoth procedures are HIFU-based, but Shurink is a subsequent technology that reduces pain and maximizes effects. The key difference is that Ultherapy® uses DeepSEE™ visualization ultrasound to perform the procedure while directly viewing the SMAS layer. For a detailed comparison, Ultherapy pageplease refer to.

How are Exosome and Re2O different?
Dr. Dongil ChoiExosome is based on cell signal transmitters and excels in regeneration, soothing, and tone improvement. Re2O is a high-molecular booster that fills the deep dermal layer, excelling in recovering inner dryness and elasticity. The appropriate booster is selected based on your skin condition and concerns during consultation.

Endoscopic Forehead Lift
How is it different from an eyebrow lift?
Dr. Dongil ChoiAn eyebrow lift involves excising skin above the eyebrow, while an endoscopic forehead lift dissects and fixes the fascial layer under endoscopic assistance through small incisions inside the hairline. It leaves less visible scarring and allows for a natural lift.

Fat Grafting
Doesn't the grafted fat all get absorbed?
Dr. Dongil ChoiPartial absorption of fat is a natural process, and our clinic uses a method that increases the survival rate by using only purified pure fat. Generally, the volume settled at 6 months is considered the final result.

Revision Rhinoplasty
When is the best time for rhinoplasty revision?
Dr. Dongil ChoiIt is best to perform it 6 months after the previous surgery. This is because the tissues stabilize and soften after about 6 months. However, depending on the state of inflammation or infection, earlier surgery may be necessary, so a consultation with a specialist is required.
