My sister is considering flying to Seoul for double eyelid surgery. She's seen many people in online groups praising the natural-looking results in Korea, but she's still wondering if it's worth the trip. Are the costs for flights, hotels, and post-operative recovery reasonable?

Her biggest concern is follow-up. What if something goes wrong after she returns to Vietnam? Will she have to fly back for a check-up? She also wants to know if anyone has had a follow-up appointment or if online consultations are sufficient?

Another thing is she's unsure how long she should stay in Seoul. She imagines the swelling will last for quite a while after the surgery, and she doesn't want to return to Vietnam while her face is still swollen. Could anyone with experience share their advice? Thank you so much!
