How do laser treatments affect dormant viruses in the skin?

Laser treatments can trigger the activation of dormant viruses in the skin, particularly in individuals who have a history of conditions such as herpes simplex virus. The application of laser energy can disrupt the normal cellular environment, potentially awakening viruses that were previously in a dormant state. This is significant for individuals undergoing laser treatments, as the process may lead to an outbreak or reactivation of viral infections.

The mechanism behind this activation often involves the inflammatory response induced by the laser treatment, which can stimulate viral replication. Therefore, it is essential for practitioners to consider a patient's medical history and inform them of the risks associated with laser procedures, especially if they have a history of viral infections. Proper precautions, including antiviral prophylaxis, may be warranted in these cases to minimize the risk of triggering viral activity.
