Excavation scars, generally, are scars that remain after the skin has been scratched and broken and has repaired itself. There is no fast way to remove scars, mainly through medication, laser treatment, abrasion and other methods of improvement. 1. Medication: Medication is the safest method for treating scars. There are many medications for treating scars, and the most commonly used ones are injectable steroids (e.g. Triamcinolone acetonide suspension), silicone agents (e.g. Silicone Cream), which are slow in showing results. 1. Laser treatment: It is the use of a specific instrument to radiate high-intensity laser energy, causing thermal damage to the tissues inside the scar, and prompting the synthesis of collagen and elastic fibers, which can achieve the purpose of improving the scar. 2. Abrasion is a kind of physical therapy, through mechanical abrasion to make the boundary between the scar and the surrounding skin become blurred, so as to achieve the purpose of fading scars. If the scar is too big, you can consider phased excision or placing a tissue expander for a period of time before scar excision. Since the treatment process is affected by factors such as personal constitution and treatment techniques, it is important to choose a regular medical institution and ask a professional doctor for an advance assessment.
