This issue is clear in my case, it must be worn. Headgear can reduce local edema, smoothing local skin, after facelift there will be a certain amount of edema, resulting in some local weight, will fall downward, local activities may appear some inconvenience, or even pulling pain, and wearing headgear can avoid these effects. The headgear usually needs to be worn for one month, 24 hours a day for the first half month. If it is inconvenient to go out to work and other times, you can consider taking it off temporarily, and after half a month it will be worn during sleep time to promote our recovery. Some people consult me that just after surgery to wear a head cover, will there be a problem of infection? First of all, it is not a headgear but a bandage that is worn just after surgery. Usually the bandage is removed after three days and the headgear is put on. After replacing the headgear, the wound needs to be disinfected once or twice a day, so there will be no problem of infection. At the same time, candidates need to note that the role of the hood is to prevent the edema part of the pull down, it plays a “pocket” role, rather than tightly strangle the head, which is not conducive to post-operative recovery.
