What should patients avoid before undergoing laser treatment?

Patients should avoid sun exposure before undergoing laser treatment because the skin needs to be in its optimal condition for the procedure. Sun exposure can lead to increased melanin production, causing pigmentation changes, which may interfere with the effectiveness of the laser treatment. Additionally, tanned skin can absorb more laser energy, increasing the risk of adverse effects such as burns or hyperpigmentation.

Maintaining the skin's natural tone helps ensure that the laser can effectively target the intended pigmentation or skin issue without complications. This precaution is essential for achieving the best possible outcomes and minimizing risks associated with the procedure. On the other hand, hydration and using moisturizer are typically encouraged for skin health, and consulting with a doctor is crucial for personalized care, making these options less relevant to the question of what to avoid before treatment.
