Yonsei SL Clinic

At 연세SL의원 (Clinic, null, Seoul), they operate on the principle of ensuring that patients do not have to worry about recurrence after undergoing a single blepharoplasty procedure. Since their founding in 1988 with a focus on blepharoplasty, they have performed over 20,000 surgeries and have a reoperation referral rate of less than 1%. To guarantee their patients' satisfaction, they provide a lifetime warranty certificate (issued at the time of surgery) that covers 100% of the cost of any future blepharoplasty procedures, free of charge, regardless of the time elapsed since the initial surgery, under their after-sales service (AS) policy.
