The standards this site is written to
This site is patient education published by Chongqing West District Hospital. It is written to the hospital’s content standards and to the advertising rules governing medical content, which is why it reads differently from a commercial clinic site.
What this site does not do
It names no device brand, no manufacturer and no product name, and describes the two instruments by class only. It quotes no wavelength, no energy setting and no price. It publishes no before-and-after gallery used as a promise, and it makes no claim that a particular result can be achieved by either option.
Both options are described alike
This is a neutral comparison. Neither a single-wavelength instrument nor broadband light is presented as the default, as the more modern option or as the answer for most people. The limitation the two share is stated once, in the same terms, rather than attributed to one of them.
Corrections
If you believe something on this site is inaccurate, raise it through the hospital administration contact. Corrections affecting clinical meaning are reviewed by the responsible physician before publication.
