I'm sorry to hear that it's been 20 days since your nose line was carved, and the bruises still won't go back. Cyanosis is one of the common complications after line carving nose, which may be caused by capillary damage during operation. Here are some possible reasons why bruises persist:

Surgical injury: Wire carving nose surgery needs to insert wire, which may cause damage to skin and blood vessels. If the large blood vessels are damaged during the operation, it may lead to congestion and bleeding.

Improper postoperative care: Postoperative care is very important for recovery. If proper nursing is not carried out according to the doctor's advice after operation, such as insufficient compression and hemostasis, premature and strenuous exercise, etc. , may lead to bruises.

Physical differences: everyone's physical condition and recovery ability are different, and some people may take longer to get rid of bruises. Factors such as age and health status may also affect the recovery time.

Improper operation: If the operation is improper, such as improper wiring or excessive force, it may lead to bruises and swelling.

If you have tried conventional treatments such as cold compress and hot compress, but the bruises still do not subside, I suggest you contact a doctor for consultation and treatment as soon as possible. The doctor may prescribe some drugs or suggest further treatment, such as physical therapy. At the same time, we should pay attention to keep the nose clean and hygienic to avoid infection and irritation.

We should also pay attention to maintaining good living habits and eating habits, such as adequate sleep, proper exercise and light diet, in order to promote postoperative recovery. If the bruise lasts for a long time or is accompanied by other symptoms, such as pain and redness. , should seek medical advice in time, so as not to delay treatment.

I want to remind you that although line nose carving is a common cosmetic surgery, it also has certain risks and complications. When choosing medical institutions and doctors, we must choose formal, professional and experienced institutions and doctors to avoid blindly following the trend and pursuing results while ignoring safety and health. At the same time, we should also understand the risks and precautions of the operation, do a good job of preoperative preparation and postoperative care to ensure the safety and effect of the operation. I hope my experience and suggestions can help you!
