How is the clinical endpoint defined in laser treatments?

The clinical endpoint in laser treatments is primarily defined by the visual and physical changes observed in the skin following the procedure. This means assessing the skin's appearance, texture, and any reduction in conditions being treated, such as hair growth, pigmentation issues, or vascular lesions. The indication of success in laser therapy is often evaluated through observable criteria, such as improvement in skin tone, the clearance of lesions, or reduction in hair density. These outcomes directly tie to the efficacy of the laser treatment applied.

In contrast, factors like patient satisfaction, treatment duration, and cost-effectiveness might influence the overall perception of the treatment process but do not specifically define the clinical endpoint. While they are important considerations in a broader patient care context, they do not directly measure the treatment's visible success or effectiveness on the skin, which is what the clinical endpoint specifically focuses on.
