What is an important pre-treatment consideration for laser therapy?

Skin hydration levels are a critical pre-treatment consideration for laser therapy because they significantly influence the skin's response to laser treatments. Well-hydrated skin can absorb laser energy more effectively, leading to improved treatment outcomes and reduced risk of adverse effects, such as burns or hyperpigmentation. Proper hydration helps to maintain the elasticity and integrity of the skin, making it more resilient during the procedure.

In contrast, makeup application, while relevant for certain treatments to ensure proper skin exposure, does not impact the efficacy of the laser itself. The type of laser used is an important factor, but it pertains more to the treatment plan rather than a pre-treatment consideration. Finally, duration of sun exposure is also a concern, especially in relation to skin sensitivity and healing, but hydration directly affects the immediate readiness of the skin for the procedure. Therefore, maintaining optimal skin hydration is paramount for a safe and effective laser therapy experience.
