The best time to apply scarring cream is usually about a week after the wound has scabbed over, i.e., just after the wound has healed and before the granulation tissue has grown, when the application can inhibit scar growth. When the skin is traumatized, if the damage reaches the dermis and subcutaneous tissues, scars will be easily formed. The application of scar cream can reduce scar formation by promoting the regeneration of keratinocytes and inhibiting the over-activation of fibroblasts. Currently, there are many types of scar creams available on the market, and the common active ingredients include epidermal cell growth factor, cumene, silicone, vitamin C, etc. Patients can use the medicine that suits them. Patients need to apply it directly on the scar surface and massage it fully until it is completely absorbed, and can use it once in the morning and once in the evening. However, if patients repeatedly experience tingling and itching during the use of the medicine, they need to stop using it in time.
