Blepharoplasty is generally categorized into short term and long term blisters. Short-term blisters can be relieved by improving lifestyle habits, while long-term blisters can be improved by double eyelid surgery. 1. Short-term blisters: Short-term blisters are caused by upper eyelid edema due to prolonged fatigue or drinking a lot of water at night. To improve this condition, you need to get enough sleep and try not to drink too much water before going to bed. 2. Long-term swollen eyes: Long-term swollen eyes are usually caused by genetic factors and are born with swollen eyes. This condition can be improved by removing the fat and peeling the skin, removing part of the orbicularis oculi muscle or resetting the lacrimal gland during double eyelid surgery according to the cause of the swelling. For patients with swollen eyes, it is recommended to go to regular hospitals for timely examination and standardized treatment under the guidance of professional doctors.
