Why do you have black eye after 4 weeks of having permanent eyeliner surgery?

A black eye after permanent eyeliner surgery can occur due to bruising from the procedure, which may take time to resolve. Even if the initial swelling has subsided, the discoloration can linger for several weeks as the body heals. Additionally, factors such as individual healing rates and skin sensitivity can influence the duration of bruising. If concerns persist, it's advisable to consult with your healthcare provider.
