Generally speaking, it is impossible to completely remove the scar before one year, and can only improve the appearance of the scar through medication, phototherapy and surgery.
For people whose scar has existed for more than one year, the scar growth has been very mature, belonging to the old scar, at this time, if you simply choose to use externally applied scar removal cream (such as compound heparin sodium allantoin gel, etc.) to remove the scar, the efficacy of the treatment will be less significant, or even ineffective, so at this time, it is generally recommended to carry out laser or surgical treatments.
At present, the clinical use of carbon dioxide fractional laser, erbium laser and other photoelectric treatment to deal with scarring, through stripping, stimulate local collagen regeneration and rearrangement to improve the appearance of scarring, but generally need multiple treatments to achieve the desired results.
If the scar affects the appearance or function, and prolonged conservative treatment is ineffective, surgery can be performed to remove the proliferated scar tissue and then reduce the tension and suture. However, surgery is an invasive operation, and there is a risk of re-formation of hyperplastic scar, and after the operation, patients should follow the doctor’s instructions to standardize the anti-scar treatment.
It is recommended that patients who wish to undergo treatment should go to the dermatology department of a regular hospital for an interview and follow the doctor’s instructions for standardized treatment.
