Many newborns are born with prominent birthmarks. To avoid affecting their child's normal development, parents often choose laser treatment. Many parents worry: Can laser birthmark removal damage the skin? Regarding this concern, let's hear from the experts below!
Does laser birthmark removal damage the skin?
Birthmarks typically appear at birth, though some emerge months later. Since most patients are children, painful removal risks accidents due to their limited self-control. Compared to traditional methods, laser removal is painless, non-invasive, and fast-acting—making it a popular choice for birthmark removal.
Does laser birthmark removal damage the skin?
Experts explain that since laser treatment absorbs minimal thermal energy into surrounding healthy skin tissue, it causes no damage. Laser birthmark removal is pain-free, so there's no need for concern.
Laser birthmark removal utilizes three effects when light energy interacts with skin tissue: photothermal, electromagnetic field, and biological stimulation. The primary mechanism is the photothermal effect.When laser light of a specific wavelength is directed at the skin lesion, it converts light energy into heat energy that is selectively absorbed. The high-intensity energy rapidly thermally decomposes, vaporizes, or shatters the abnormal tissue into microscopic fragments. These fragments are then phagocytosed by the body's phagocytes and expelled, achieving the goal of birthmark removal.
