Hypertrophic scars are relatively common in clinical practice. For instance, a patient who has undergone surgery may develop hypertrophic scars at the incision site, or a patient who has suffered a trauma may develop hypertrophic scars at the site of the injury. Once hypertrophic scars have formed, they can be massaged without any issues. Massage does not lead to a worsening of hypertrophic scars, nor does it cause inflammation, carcinogenesis, or other related conditions. However, it is important to remember to massage gently and not use excessive force.
