As long as there is a wound, there will be scar, but the scar can be reduced by the following methods: first, pay attention to the diet, for example, do not eat too spicy food, such as chili, spicy strips, spicy hot pot, etc., which tend to promote scar proliferation. Secondly, you can eat more foods that help local wound healing and reduce scarring, such as high quality protein with low fat and low cholesterol content, fish, shrimp, etc. Also, you can properly eat fruits rich in B and C vitamins, such as apples, kiwi, bananas, etc. Local scar paste or scar cream can be applied after healing, which can inhibit scar proliferation. If the patient is a keloid, he or she can go to a specialized medical aesthetic department and get scar removal medication to inhibit scar growth. If necessary, this can also be done topically to reduce scarring.
