The formation principle of double eyelids is such that the skin and deep tissues are formed through surgery, while the buried double eyelids are only achieved through a thread, so the effect of buried double eyelids is limited. If the thread slips out of the original tissue within a short period of time, the maintenance time may be very short, so the maintenance time of the buried eyelid depends on whether the candidate is suitable for the buried eyelid. If the upper eyelid is very thin and tight, there are no swollen eyeballs, no excess loose skin, and you don’t usually put on double eyelid stickers, the maintenance time for such a person may be very long, or it may be several years. Generally speaking, I think the maintenance time of the eyelid can range from a few months to several years, depending on the original eye condition of the candidate. It is meaningless to pursue minimally invasive surgery and ignore the results.
