The nano scarless double eyelid, which is often referred to as the double eyelid buried line method, can be maintained for as long as the eye condition. If the patient’s eye skin is relatively thin and not lax, and there is no excess fat in young people, some people can keep it for three to five years, while some people can keep it for up to ten years. If the eye skin condition is not ideal, swollen eyes, thicker skin, and thicker subcutaneous fat, it is not suitable for buried eyelid. Over time, most people’s eyelids will slowly disappear or become lighter, so there is no permanent double eyelid. Buried double eyelids have a short recovery period, are less likely to leave scars, and have natural results. After surgery, you can use ice on your eyes for 1-2 days to reduce the swelling and shorten the double eyelid recovery time. The eye activity should not be too much within 48 hours after the eyelid surgery to prevent bleeding from the incision. Of course, after 2 hours of surgery, you can do appropriate eye opening and closing exercises (not too hard), which can help reduce swelling, avoid abnormal adhesions and make the eye shape natural as soon as possible. However, not everyone is suitable for this surgery. If a patient’s eyes do not meet the indications for eyelid surgery and they are forced to undergo eyelid surgery, the eyelid shape will be affected and will not last long. After surgery, patients need to pay attention to their daily habits and dietary influences to avoid affecting the skin and wound recovery.
