Is laser scar removal effective for old scars?
I am 42 years old this year. When I was young, I got a scar on my leg from a fall. I heard that laser scar removal is very effective, and I would like to know whether laser treatment works for old scars.

In general, laser scar removal has a certain effect on old scars. Laser scar removal works by using laser energy of specific wavelengths to target scar tissue, stimulating collagen remodeling and regeneration to improve the appearance of scars.
For older scars that have been present for a long time, the effectiveness of laser treatment may not be as significant as it is for newer scars. However, it can still help to some extent in reducing scar elevation or depression, making the scars flatter. Old scars are typically more stable and have a more complex tissue structure, but lasers can be adjusted to target the specific characteristics of old scars. For pigmented old scars, lasers can break down pigment particles, promoting their metabolism and fading, thereby improving scar color.
It should be noted that the effectiveness of laser scar removal may vary due to individual differences, and it cannot completely remove scars, only improve their appearance to some extent. In addition, laser scar removal usually requires multiple sessions to achieve optimal results. There may be mild discomfort during treatment, and the skin may become red and swollen afterward, but these symptoms typically subside within a few days.
It is recommended to consult and undergo evaluation at the dermatology or plastic surgery department of a reputable hospital, where a professional physician can develop a personalized treatment plan based on the patient's specific condition. After treatment, it is important to follow the doctor's advice, properly care for the skin, and avoid direct sunlight to promote healing and prevent pigmentation.
