Technology · Patient guide
A plain-language guide to laser, light, ultrasound and radiofrequency technologies.
Energy-based devices use controlled light, laser, ultrasound or radiofrequency to interact with a selected tissue target. The mechanism, depth and intended response differ by technology.
A device category is only the start of the explanation. The exact platform, mode, area and clinical target must be defined.
Firmness, pigmentation, texture, redness and hair concerns can involve different technologies and targets. A generic claim about laser or tightening is incomplete if it does not identify the actual procedure.
The clinician should explain why one mechanism is relevant and which alternatives work differently.
Device settings, passes, intervals and course length are clinical parameters. They depend on the exact device, indication, area and patient response.
Do not copy another person's settings or assume that stronger energy is better.
Common questions
Use these answers to prepare a more specific consultation question.
No. Platforms, wavelengths, modes and treatment targets differ.
Not necessarily. Settings must balance the intended response with patient- and area-specific safety considerations.
