Many patients often ask me how to remove their scars and whether scar removal creams are effective. It is certain that scar removal cream has some effect, but only for new scars within one year, and the earlier you apply it, the better the effect. For old scars that are older than a year old, scar removal creams are not effective. So what is the definition of old scars? Generally, scars that are older than one year are considered old scars. They are mostly caused by external skin trauma, such as burns, scalds, scrapes, surgeries, and other cases. How to treat old scars? It is possible to classify old scars into wider scars and narrower scars. For a wider old scar, the depression or bulge can be removed, dilators can be implanted, and depending on the situation, internal and external super tensioning fine sutures can be selected for the purpose of tension reduction, and after the stitches are removed, it is also necessary to do the regular care such as tension reduction and application of scar removal medication according to medical prescription. Wider old scars can also be treated with fractional laser or ion beam plasma. For the second narrower old scars, if the skin tension at the scar location is sufficient to meet the conditions for excision, a one-time excision can be performed, together with super tension reduction fine suturing, and adherence to care after removal of the stitches as prescribed by the doctor, which is a very thin line after recovery, and the normal social distance is not obvious. If the skin tension at the scar location is not enough for excision, then red light can be used to repair the scar, and if pigmentation is present, picosecond laser can be used to repair it, all of which will achieve good results. It doesn’t matter if you have scars, find a professional doctor to make a correct diagnosis, formulate a reasonable and effective treatment plan according to the actual situation, follow the medical advice and follow the treatment course, and adhere to the care will definitely improve the scars to a great extent.
