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 and no product, and describes devices only by their class. It quotes no price, no dose, no percentage and no wavelength. It publishes no before-and-after gallery used as a promise, makes no claim that a particular result can be achieved, and does not present either kind of light source as the default choice.
No outcome is promised
Nothing here should be read as an offer of a specific result. Planning depends on the target, the skin tone and the history in front of the clinician, and any decision to treat is made only after a personal assessment, and often after a test area.
Why the comparison is written this way
Both light sources on this site are offered at Chongqing West District Hospital, so the page that recommends one of them to everyone would be recommending the wrong treatment to some readers. The comparison is written to describe both accurately, including their risks and their limits, and to say when neither should be used.
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.
