Abstract

To explore the related factors of pigment alteration after the Q-switched laser treatment. After the Q-switched laser treatment, the side effects in patients were observed, recorded and analyzed. The results showed that the incidence of pigment alteration is directly related to age (OR1=2.519, confidence interval 0.996-6.366; OR2=2.519, confidence interval 0.978-6.488; OR3=8.311, confidence interval 3.312-29.695). Besides, the pigment alteration is also correlated to the skin types, but not to gender, kind of diseases, parts of body, intensity of ultraviolet radiation, character of work, wavelength of laser and the energy of laser. Older patient is easier to have pigment alteration than younger patient. Pigment alteration may be obvious in a pigmented individual than a lightly pigmented individual.
