It is said that health checkups during visits to one’s home country are becoming increasingly popular among Korean nationals living overseas.
Because medical service prices in South Korea are much lower than in the United States and the medical system is far more reasonable, more overseas Koreans (ethnic Koreans abroad) are making time to receive medical services in Korea.

When overseas Koreans come to Korea, many of them hope to receive medical services such as cosmetic procedures in addition to services like health checkups.
In particular, when it comes to plastic surgery, many overseas Koreans prefer to have surgery in Korea, where there is extensive experience operating on Asian patients, rather than at plastic surgery clinics in the United States that mainly treat white patients.
In fact, no matter how famous American plastic surgery clinics may be, it is true that their experience with cosmetic surgery for Asian patients is much more limited.

In some cases, double eyelids do not form after upper eyelid surgery performed in the United States.
Even for the simplest upper eyelid surgery, the surgical methods for white and Asian patients are different. In upper eyelid surgery performed on white patients, there is no step that creates a double eyelid, so there are cases where a double eyelid does not form after surgery.
And according to surgery statistics published by the American Society of Plastic Surgeons, the United States mainly performs body-contouring procedures, and even in facial plastic surgery, the types of procedures and their frequency are very different from those in Korea.

In recent years, as the proportion of Asians in the United States has increased, Korean- and Chinese-American plastic surgeons in the U.S. have also come to Korea for training to learn Asian plastic surgery.

Westerners and Asians not only have different skin types and facial shapes, but also many differences in the anatomical structure of the eyes and nose.
That is why, in the field of cosmetic surgery for Asians, there are separate plastic surgery textbooks specifically related to surgical methods.

Moreover, when the cultural differences are significant, it is often difficult to explain Asian aesthetic standards to a Western doctor, no matter how experienced the plastic surgeon may be.
As for cosmetic surgery fees, medical costs in developed countries such as the United States and Canada are known to be much higher, and I understand that anesthesia fees are also charged separately when sedation anesthesia is used.
In many ways, if you are an overseas Korean, it has many advantages to have plastic surgery in Korea.
Of course, round-trip airfare to come to Korea and the cost of staying there may be incurred, but if you plan your surgery in advance when you come for a health checkup or while taking care of other matters in Korea, it is possible to arrange a surgery schedule that takes recovery time into account.
