SUMMARY

Skin vibrates at the molecular level due to thermal energy, but it does not exhibit a steady frequency. The individual atoms and molecules within the skin vibrate independently rather than moving uniformly. While the concept of using a laser to detect these vibrations is proposed, it is established that lasers cannot measure atomic or molecular vibrations due to their minuscule size. Instead, thermal imaging cameras are suggested as a more viable tool for detecting skin vibrations.

Does skin vibrate at the molecular level?
If so does it have a steady frequency?
If so would it be possible to use a laser to detect said vibration from a distance?

Yes, your skin does vibrate at the molecular level due to thermal energy but it does not have a steady frequency. Note that your skin does not vibrate like a drum does, with the entire surface moving together. Instead the individual atoms and molecules vibrate on their own.

I don't see any way of using a laser to measure the vibration of the atoms or molecules of your skin. Atoms and most molecules are simply far too small for a laser measure.
