Basic Double Eyelid Lines for Customized Eye Surgery
Double eyelid surgery begins with creating a line on eyes that don't have one.
By creating a beautiful double eyelid line, a dramatic transformation to clear and pretty eyes is induced.
Therefore, it's crucial to consider the overall proportion and harmony of the individual's face and customize the most appropriate line.
Double eyelid lines can be broadly divided into three types:
▶ In-line
A double eyelid line that starts from the inner corner of the eye.
Most suitable for Koreans and the most commonly seen line.
▶ Out-line
A double eyelid line that starts from the outer corner of the eye.
Suitable for those who desire large and distinct eyes.
▶ In-out line
A line that is an intermediate form between the in-line and out-line.
The double eyelid line most commonly found among celebrities.
The most popular type of line for those considering double eyelid surgery.
Just because a line is beautiful doesn't mean it will suit everyone, so it's best to proceed by considering your facial features, eye characteristics, and surrounding conditions.

Should I get double eyelid surgery?
If any of the following apply to you, you might consider upgrading your beauty with a beautiful double eyelid line:
Those who want to create a natural and distinct double eyelid line.
Those with a hidden double eyelid on only one eye or asymmetrical lines.
Those who want to adjust the height of their double eyelid.
Those who have double eyelids but they occasionally disappear.
Those with drooping eyelids or eyelashes that poke their eyes.
Those with a lot of fat on their eyelids, making their eyes and impression appear dull.
If a double eyelid line alone isn't enough, combining it with canthoplasty, which offers the greatest synergistic effect in eye surgery, is also a wise choice.
Canthoplasty is a necessary method for those who have a stuffy-looking image due to eyes with short horizontal and vertical lengths.
Since the approach varies depending on the characteristics of the eye shape, it is best to consult thoroughly with an experienced plastic surgeon who possesses medical knowledge, proficiency, and know-how from various cases before undergoing surgery.
