What is an important consideration before performing laser treatment on a patient?

Before performing laser treatment on a patient, one of the most critical considerations is the patient's skin type and their history of photosensitivity. This is essential because different skin types react differently to laser treatments. The Fitzpatrick scale, which categorizes skin types based on their response to UV light, is often a reference tool in this context. Patients with higher Fitzpatrick types may be at increased risk of complications, such as hyperpigmentation or burns, making it vital to tailor the treatment approach accordingly.

Additionally, a history of photosensitivity is crucial to consider, as it indicates how the patient's skin reacts to light, which can inform the selection of the laser type, the intensity of the treatment, and the pre- and post-treatment care required to ensure the patient's safety and effectiveness of the procedure. Understanding these factors helps in minimizing risks and achieving optimal results.
