The use of povidone-iodine on the wound will not leave a mark. Because povidone iodine is a complexed iodine that is yellow in color but does not form hyperpigmentation, patients can use the medication normally. After there is a wound, a solution of povidone-iodine is usually used to disinfect it. If the infection is more serious, it needs to be disinfected with hydrogen peroxide and then rinsed with salt water. After the injury, patients should try to avoid drinking beverages containing alcohol and do not eat too spicy food, which may lead to itching, discomfort and other symptoms of the wound, and at the same time, it is easy to lead to scarring hyperplasia. Patients can consume fresh fruits and green vegetables and low-fat high-quality protein appropriately to promote wound healing. During the healing process, try not to be exposed to the sun to prevent hyperpigmentation and affect the aesthetics, while the wound should not be exposed to water to prevent infection.
