As more and more people are concerned about their appearance, how to make themselves look younger yet let others see the traces of the surgery is the cosmetic surgery result that many people hope to get. Eye bag removal is one of the most common cosmetic surgery procedures, usually divided into internal and external eye bag methods, internal eye bag incision scars are hidden so you can not see the surgical incision scars, external eye bag incision must be made from the lower eyelid skin incision, so the incision scars are inevitably left after surgery. At present, there is no technology to completely eliminate the skin incision scar, only to make the scar hidden in an invisible position or make the scar inconspicuous. How to make the incision scars not obvious after external eye bag surgery should be considered from a variety of factors, mainly including surgical factors, the patient’s own factors, and reasonable post-operative care and protection factors. The main surgical factors are: reasonable surgical incision design, minimally invasive operation, early and good healing of the incision, etc. The patient’s factors include: for people with tight skin, skin incision can be avoided; for people with a tendency to scar growth, skin incision should be carefully considered; male patients should avoid skin incision or selective use of skin incision as much as possible. Reasonable post-operative care and protection are also crucial, mainly: strictly comply with doctor’s orders, protect the incision for early healing, avoid spicy and hairy foods after surgery, and avoid activities that can easily cause scar growth during the recovery period, such as hot springs and saunas. Although eye bag removal surgery is a common cosmetic surgery, in order to reduce the risk of surgery, it is advisable to choose a qualified and experienced surgeon to operate in a regular and qualified medical institution, and reasonable post-operative care and protection in order to achieve the ideal post-surgical results.
