Some of my friends came to ask: “Scars don’t hurt or itch does it mean that they don’t need to be treated?” No, you have to know that scars don’t hurt or itch doesn’t mean they don’t grow anymore. Most of the scars that come to the hospital are due to the great impact of scars on life and work. Initially, it is only a very small piece of scarring, because they do not pay attention to it, which leads to increasing scars, and ultimately, it brings great financial pressure and pain to the patients. First of all, we need to understand what a scar is. It is an overgrowth of abnormal scar tissue with strong proliferative ability that forms after healing from skin injuries caused by various reasons. Scars are usually higher than the surface of the skin, tough, reddish in color, and spreading to normal skin. They usually have no natural tendency to fade, and are especially prone to recurring after surgical excision, and are even larger than their original extent after recurrence. It usually grows on the upper half of the body, favorably on the forehead, back, shoulders, bilateral jaw margins, ears and other parts. Some are spontaneous; some are caused by mosquito bites and vaccinations; some are caused by trauma and surgery; and many are due to acne infections that grow in teenagers. Some of them even have the risk of becoming cancerous if not treated in time . Therefore, even if the scars do not hurt or itch, we recommend that you get treatment as soon as possible. For scars, we suggest: 1, need to keep the surface of the scars and the surrounding cleanliness 2, if the scars have itching, must not go to scratch, you can use your hands to gently pat to stop the itching. 3, light diet: try to avoid spicy and stimulating food 4, if there are scars on the body, you should try to avoid some unnecessary surgery 5, for scars should be actively prevented and treated in the early stage, but not blindly. 6, do not simply choose to have stimulating methods of treatment of scars, otherwise it will recur more seriously, must be combined with scar prevention and comprehensive treatment.
