Most scars will probably flatten out after a period of scar proliferation.
Scars, in fact, are a process of repairing the skin after an injury, and the collagen that forms them is a way to fill in the damaged tissue. The scar repair process can form depressed scars if they are not filled properly. If it overproliferates, hyperplastic scars can form.
Each person’s scar problem is different, and the specifics vary greatly. If you are a scarred person yourself, you may be left with a permanent scar after the proliferative period of scarring. However, most patients outgrow the scar proliferation phase and the scars may flatten over time.
After the scar proliferation period, if the scar fails to flatten for a long time or has a tendency to grow outward, it is necessary to go to the dermatology department of the hospital, and under the guidance of the doctor through local injections and, if necessary, surgical treatment.
