Once an injury occurs, it is very likely to develop hypertrophic scars, and the appearance of such scars is related to the individual's constitution, often accompanied by symptoms such as pain. When this condition occurs, specific treatments are definitely needed for improvement, typically using laser surgery as the main treatment, or it can be removed at once through surgical operation, which helps improve the condition. Of course, hypertrophic scars can also be improved through some physical therapy methods, such as by adjusting in different degrees, like acupuncture, which can fade the scars by improving local blood circulation. However, physical therapy is just one aspect; consistent improvement in lifestyle habits to avoid recurrent stimulation of hypertrophic scars is also crucial for recovery.
