Why can photosensitivity complicate laser treatments?

Photosensitivity complicates laser treatments primarily because it can lead to increased risk of burns and pigmentation changes. When a patient has heightened sensitivity to light, their skin may react more intensely to the energy delivered by the laser. This reaction increases the likelihood of adverse effects, such as thermal injuries (burns) or changes in skin pigmentation, which can manifest as hyperpigmentation or hypopigmentation following the procedure.

In terms of treatment considerations, a practitioner would need to be particularly cautious with dosage and laser settings to minimize these risks. Proper assessment and pre-treatment screening for photosensitivity are thus critical in planning safe and effective laser procedures. Furthermore, those with photosensitivity may need additional protective measures during treatment to prevent complications, which can complicate the overall treatment protocol and patient management.
