Many PDT devices come with intelligent control systems. These systems allow users to easily adjust settings such as light wavelength, intensity, and treatment time through intuitive interfaces, which may include touch - screen displays or simple button controls. Some devices even feature built - in sensors that can detect the skin type and condition in real - time, automatically adjusting the treatment parameters for a personalized and effective experience. In addition, safety features are integrated into the design. Overheating protection, automatic shut - off mechanisms in case of malfunction, and protective eyewear for users are just some of the safety - oriented design elements. With its innovative design, Shanglaite's PDT device beauty technology offers a cutting - edge solution that meets the evolving needs of modern beauty treatments.
