A while ago, after epicanthoplasty, thread was left behind and a scar formed, so I had the thread removed and had epicanthoplasty, upper canthoplasty, and buried-suture double eyelid surgery.
The scar didn't disappear completely, but it faded a lot, and the double eyelid line also settled well.
The hospital is a somewhat classic single-doctor clinic, and the director is older, so if you're looking for a clean and flashy place, it may feel uncomfortable, but because he had experience, I trusted him more.
