Abstract
A method for the prevention of a scar on the skin of a patient after the beginning healing of a wound or surgical site on that patient. The method comprises the steps of providing an optical radiation apparatus with a handpiece communicating therewith, energizing the optical radiation apparatus to provide a beam of light, directing the light beam onto a wound or surgical site of a patient after 2 days and before 2 months from the date of injury or surgical procedure to the patient. The beam has a wavelength range of about 530 nm to 1000 nm and the beam has a fluence range of from 2 J/cm.sup.2 to 12 J/cm.sup.2. The beam is preferrably generated by a pulsed dye laser apparatus.
