It is difficult to treat scars and keloids with a single procedure and
multidisciplinary treatments are needed. Since the 1980s, laser
treatment has become one of the effective treatment options. Recently
various laser equipments are available for different types of scars and
With regard to laser-tissue interactions, there are two types of laser
treatments, one is High-reactive Level Laser Treatment (HLLT), and the
other is Low-reactive Laser Therapy (LLLT). We can use both
photobiological reactions to obtain various clinical effects.
For the treatment of scars and keloids, we should make collected
diagnoses based on the characteristics of colors and configurations.
According to the type of scars, we must select the appropriate laser
devices, and determine the parameters of irradiation depending on the
expected photoreactions, HLLT and LLLT.
It is important to understand laser-tissue interactions and make
appropriate irradiation plans, which is the key to achieving good
