What is the purpose of a patch test in laser treatments?

The purpose of a patch test in laser treatments is to assess the patient’s skin reaction to the laser. This is a critical step in ensuring safety and efficacy, as it allows practitioners to observe how a small area of the skin responds to the specific laser energy before applying it to larger areas. By evaluating the skin's reaction, including factors like inflammation or pigmentation changes, providers can adjust treatment parameters if necessary to minimize adverse effects during the actual procedure. This testing helps to ensure that the chosen laser parameters are suitable for the individual’s skin type and condition, ultimately paving the way for a more successful laser treatment experience.
