Thus, the application of radiation in such cases had to be limited. Laser therapy,the use of different wavelengths of laser light, has been used for the treatment of keloids and hypertrophic scars for more than 20 years.15,16 However, the administration of this therapy type results in the destruction of not only diseased but also of normal tissues, leading to adverse reactions. Furthermore, its clinical application is more expensive and subjected to restrictions.
