Most eyelids last 2-3 years, with a very small percentage lasting more than 5 years. Double eyelid surgery is one of the safer and less damaging types of double eyelid surgery. Non-absorbable sutures are used to lift the skin under the eyes, creating a double eyelid effect that is visible to the naked eye. The effect of double eyelid surgery is relatively short-lived, with the majority of patients lasting about 2-3 years, and a few patients with better absorption results lasting more than 5 years. However, due to the gradual thickening of the upper eyelid, it will inevitably affect the postoperative effect and may revert to single eyelid. If you want to maintain the effect of double eyelids for a long time, you may need to consider having it done again. Although double eyelids are easy to perform and do not require removal of stitches, it is recommended to avoid contact with water for about 7 days after surgery. If swelling occurs, it is recommended that anti-inflammatory medication be taken under the direction of your physician to relieve symptoms.
