For ordinary scars, we must pay attention to protection within 3 ~ 6 months after scar formation. Locally avoid sun exposure and wind and sand stimulation. It is best not to use cosmetics on the affected area, and do not knead it repeatedly with unsanitary hands to keep it clean, which can effectively prevent pigmentation. Drugs can also be used externally to inhibit scar hyperplasia and pigment deposition or loss and promote scar softening.
Be patient when taking medicine, and it is not advisable to change medicine frequently. It will be better to apply pressure or massage locally for 3 ~ 5 minutes after taking the medicine.
