Botox is a toxin produced by Clostridium botulinum, a neurotoxin originally used to treat facial muscle spasms and other muscle movement disorders by paralyzing muscle nerves to stop muscle spasms, and later used in medical aesthetics. Botox can block the nerve impulses between nerves and muscles to relax the small over-contracted muscles, thus achieving the effect of wrinkle reduction. Alternatively, it can be used to temporarily paralyze muscles, causing them to atrophy due to loss of function, to achieve the purpose of sculpting lines, which is commonly referred to as wrinkle removal and face slimming. The majority of oriental people have single eyelids, and there is no shortage of people who want to become double eyelids, but how to make up your mind, what hospital and what doctor to choose is very troubling, many people know that the medical doctors can treat major diseases, serious illnesses, but do not know that the plastic surgery department of tertiary hospitals can do cosmetic surgery. We have doctors who have studied at Beijing Plastic Surgery Hospital and Shanghai Ninth Hospital and have years of experience and insight, so we would like to offer some advice to those who are interested. Double eyelid (blepharoplasty) is one of the most common and established procedures in plastic surgery. The first thing you need to know is about two things: first, about the hospital and the doctor: whether the hospital and doctor you are looking for are qualified and experienced enough to do this type of surgery; whether your surgeon can understand your ideas and requirements, and whether he or she can reach a consensus with you, i.e. whether the aesthetic orientation is the same; as a doctor, you are expected to have some knowledge, some requirements and ideas, and not to be at the mercy of the doctor. The second is the understanding of the surgery and their own conditions: 1, their own eye conditions, thin eyelids, long eye fissure, open eyes, the effect will be good, while the eye distance is wide, swollen eyelids, small eyes, thick skin will be greatly reduced, but and their own pre-operative than the same will be improved, so before the surgery has to have a reasonable expected value. 2.No local inflammation, no trachoma, red eyes, no oral anticoagulants, menstrual regulating drugs and supplements, etc., avoid menstruation, and inform the doctor truthfully whether you are taking hormones for other diseases before surgery. 3, as for the specific surgery should be combined with their own eye conditions and doctor consultation suitable for their own, rather than just “hearsay” or chase “Korean stream”. 4, to understand the post-operative process, the general post-operative ice 24-48 hours, natural swelling after 3 days more began to gradually reduce the swelling, full recovery to not easy to see the need for about 3 months, older, loose skin, de-fatted people may need longer time, to have the heart to prepare and arrange.
