How does laser hair removal work?
An explanation written for one device is not automatically the explanation for another.
Why the mechanism is left to the societies
This page does not restate the mechanism from memory. Two professional-society pages explain it, and they are the better source. What this page adds is a way to read them and to check a clinic's own description against them.
Which device does the explanation describe
"Laser hair removal" is a label, and clinics use it for more than one device. Reading footnotes first means asking which device and which setting a description refers to, because an explanation of how the method works is only as specific as the device it describes.
The AAD laser hair removal overview is the dermatology society's plain-language description. The ASDS page on laser therapy for unwanted hair comes from the dermatologic surgery society. Read both and note where they use different words for the same step, since that is where a clinic's marketing is most likely to blur the details.
Questions that test a clinic's explanation
Ask the provider which device they use and how it differs from others they could have chosen. Ask who operates it and what training that person has. Compare the explanation you get with the two pages above and flag anything that does not match.
Method fit is a clinical call
We read and compare explanations rather than practice medicine, so a licensed clinician who has examined your skin is the right person to say whether the method suits you.
