Q-switch nanosecond laser as innovative and instant management for bruises discoloration, a case report

Bruises is one of the most common side effects of injectable cosmetic procedures, which leads to stress to clients and health care providers. Conventional treatments such as vitamin K preparation, cold compresses, and Arnica cream have been used to treat bruises, yet these treatments do not provide instant results. The purpose of this report is to present a case in which different wavelengths of Q-switch nanosecond laser was used to treat cosmetic injection-related bruises.Four different laser wavelengths were used to treat injection-related bruises. Pictures were taken before and after the treatment and analyzed using the RGB color histogram and the Image color analyzer from http://mkweb.bcgsc.ca/. Pictures showed a close to complete resolution of the bruises and discoloration. The results of this report suggest that using multiple selective wavelengths, in shorter pulse width but higher fluence would be more effective in resolving bruise-related discoloration compared to using one wavelength with longer pulse width.
