What should patients be advised to do after a laser treatment regarding their skin?

Following laser treatments, it is essential for patients to understand the importance of skincare and sun protection to promote healing and prevent complications. Advising patients to apply moisturizers is beneficial because it helps maintain hydration in the skin, which can be compromised following a procedure. Keeping the skin moisturized aids in the healing process and can alleviate any dryness or irritation that may occur.

Avoiding sun exposure is equally important after a laser treatment. The skin is often more sensitive and vulnerable to UV damage immediately post-treatment, which can lead to hyperpigmentation, irritation, or even scarring if exposed to the sun. By limiting sun exposure, patients can minimize these risks and promote a better healing environment.

Other options may not provide the necessary care or might put the patient's skin at risk. For instance, exposing the skin to UV light for vitamin D can cause harm rather than benefit post-treatment. Not using products at all for a week could lead to dryness without offering any beneficial hydration, and immediately using any available skin products may introduce irritants or inappropriate ingredients that could hinder recovery. Thus, option C outlines the optimal aftercare strategy for skin following laser treatments.
