In May 2018, I had double eyelid surgery with natural adhesion and an in-out line from Director Shin Kyung-jin, and I am very satisfied.
During the consultation process, they clearly picked out the line I wanted, and I felt like they understood my clumsy explanation better than anyone, so I went ahead with the surgery.
By about one month, the major swelling had gone down, and the remaining swelling lasted until around 3 months. Now nobody knows I had double eyelid surgery.
When my eyes are closed, you cannot see the line at all. If you like a natural line, definitely go see this doctor.
